                 IN THE UNITED STATES DISTRICT COURT 
                 FOR THE NORTHERN DISTRICT OF TEXAS 
                           AMARILLO DIVISION 
OPEN CHEER & DANCE 
CHAMPIONSHIP SERIES, LLC, et ail., 
         Plaintiffs, 
v.                                              2:23-CV-155-Z 
VARSITY SPIRIT, LLC, et al., 
         Defendants. 
                   MEMORANDUM OPINION AND ORDER 
     Before the Court is Defendants’ Motion to Strike Disclosures Under Rule 26(a)(1) and 
26(a)(2)(C) and For Expedited Briefing and Consideration (“Motion”) (ECF No.  143), filed June 
6, 2025. Plaintiffs responded on June 16, 2025. ECF No.  145. And Defendants replied on June 
23, 2025. ECF No.  148. Plaintiffs also filed for leave to file their response under seal. ECF No. 
146. The Court required additional briefing on that motion. ECF No.  149. The Motion is now 
ripe.  Having reviewed the Motion,  briefing,  and relevant law,  the Motion is  GRANTED  in 
part.  Plaintiffs are ORDERED to supplement,  within  seven days of this Order’s date, 
their initial disclosures and expert disclosures to comply with Federal Rules of Civil Procedure 
26(a)(1)(A)G) and 26(a)(2)(C)(i)(i1) as explained in this opinion. 
     BACKGROUND 
     Plaintiffs sued Defendants, alleging anticompetitive activity against Plaintiffs intended 
to prevent  Plaintiffs from “gaining a foothold in  the  market” because  Defendants “feared it 
would take  away their control of the  market.”  ECF No.  1  at 6.  Plaintiffs’ claims center on 
violations of the Sherman Antitrust Act, the Clayton Act, and the Texas Free Enterprise and 
Antitrust Act of 1983, among others. Jd.  at 39-44. Plaintiffs argue Defendants’ “cheer cartel” 

colluded to enact group boycotts and other collusive activity to prevent Plaintiffs from competing 
against them for All Star cheer competitions. Jd. at 6, 6-9. 
     Plaintiffs  produced  their  initial  Rule  26(a)(1)  disclosures  in  fall  2024.  Defendants 
objected to deficiencies in Plaintiffs’ initial disclosures in October 2024.  ECF No.  143-1  at 2. 
Defendants  noted  that  Plaintiffs’  initial  disclosures  only  “generally  identified  ‘current  and 
former  agents,  employees,  and  custodians  of  record”  for  all  parties  and  other  unnamed 
individuals, “TBD.” ECF No. 143 (quoting ECF No. 125-7 at 2-4). Plaintiffs responded that they 
intended to supplement their initial disclosures to “identify additional persons [they] may use to 
support Plaintiffs’ claims.” ECF No. 143-3 at 2. Plaintiffs supplemented their initial disclosures 
on March 6, 2025. ECF No. 125-8. These disclosures still identified categories of individuals for 
over 100 entities. Jd. Defendants again objected. ECF No.  125-15. And Plaintiffs refused to fix 
the  identified  problems.  ECF  No.  143-4  at  2  (‘We  disagree  with  your  characterization  of 
Plaintiffs’ initial disclosures. Defendants seem to be trying to manufacture issues that do not 
exist.”).  Plaintiffs supplemented their initial disclosures for a second time on April  18,  2025. 
ECF  No.  143-5.  This  supplement  did  not  resolve  the  identified  issues.  See  id.  Thus,  these 
second-supplement initial disclosures are the subject of this Motion. 
     The same day Plaintiffs supplemented their initial disclosures for a second time, they 
produced their expert disclosures. ECF No.  143-6.  Defendants objected to these, too, because 
they contended that the owners of Plaintiff organizations should not be designated experts, and 
the disclosures did not meet Rule 26(a)(2)(C)’s requirements. ECF No.  148-7 at 2-3. Plaintiffs 
supplemented their expert disclosures on May 7,  2025.  ECF No.  143-8. These supplemented 
expert disclosures are the subject of this Motion.

     LEGAL STANDARD 
     I. Federal Rule of Civil Procedure 26(a)(1)(A)(i) 
     Federal Rule of Civil Procedure 26(a)(1)(A)(i)  requires parties to disclose initially the 
“name  and,  if known,  the  address  and  telephone  number  of each  individual likely to  have 
discoverable information—along with the subjects of that information—that the disclosing party 
may use to support its claims or defenses.” FED. R. CIV. P. 26(a)(1)(A)(i) (emphasis added). A 
party may rely on “the information then reasonably available to it” when making these initial 
disclosures but cannot excuse deficient disclosures “because it has not fully investigated the case 
or because it challenges the sufficiency of another party’s disclosures or because another party 
has not made its disclosures.” FED. R. CIv. P. 26(a)(1)(E). “But not everyone is going to have all 
that  information  at  the  outset  of  litigation.”  Reyna  v.  Epiroc  Drilling  Sols.,  LLC,  No. 
3:23-CV-1005, 2025 WL 317568, at *6 (N.D. Tex. Jan. 28, 2025). So parties have a continuing 
duty to supplement their initial disclosures “if [they] learn[] that in some material respect the 
disclosure . . . is incomplete” and more details comes to light. FED. R. CIV. P. 26(e)(1). 
     II. Federal Rule of Civil Procedure 26(a)(2)(C) 
     Federal  Rule  of Civil  Procedure  26(a)(2)(C)  requires  a party  to  disclose  “the  subject 
matter on which the [expert] witness is expected to present evidence under Federal Rules of 
Evidence 702, 703, or 705” and to disclose “a summary of the facts and opinions to which the 
[expert] witness is expected to testify” for all expert witnesses who are “not required to provide a 
written  report.”  This  disclosure  requirement  provides  the  opposing  party  with  notice  of 
approximately  what  a  nonretained  expert  witness  will  testify  about.  See  Galvez  v.  KLLM 
Transp. Servus., LLC, 575 F. Supp. 3d 748, 756 (N.D. Tex. 2021). These disclosures must provide 
a summary of the nonretained expert’s opinions and not only the topics of testimony. See EKverett 
Fin., Inc.  v.  Primary Residential Mortg., Inc.,  No.  3:14-CV-1028, 2017 WL 90366, at *2 (N.D. 
Tex. Jan. 10, 2017). Additionally, these disclosures must provide the specific factual basis for the

enumerated opinions. Jd. The Rule’s use of “summary” means that an “abstract, abridgement, or 
compendium  of the  opinion  and  facts  supporting  the  opinion”  suffices.  Anders  v.  Hercules 
Offshore  Servs.,  LLC,  311  F.R.D.  161,  164  (E.D.  La.  2015).  Thus,  “undue  detail[s]”  are  not 
required—but discrete, summarized opinions are.  See FED. R. CIV. P. 26(a)(2)(C) committee’s 
note  to  2010  amendment;  see  also  Everett,  2017  WL  90366,  at  *2  (finding  no  “controlling 
precedent that governs the level of detail required in disclosures under this  Rule”). And the 
specific facts that form the base of those opinions are required, too. See Galvez, 575 F. Supp. 3d 
at 756 (“The disclosure must, at the very least, state opinions, not merely topics of testimony, and 
contain a summary of the facts upon which the opinions are based.” (emphasis added) (internal 
quotation omitted)). 
     III. Federal Rule of Civil Procedure 37(c)(1) 
     Federal  Rule  of  Civil  Procedure  37(c)(1)  provides  that  if “a  party  fails  to  provide 
information or identify a witness as required by Rule 26(a) or (e), the party is not allowed to use 
that information or witness to supply evidence on a motion, at a hearing, or at a trial, unless the 
failure was substantially justified or is harmless.” The disclosing party has the burden to prove 
that the failure to disclose was substantially justified or harmless. See Sightlines, Inc.  v. La. 
Leadership Inst., No. 3:13-CV-527, 2015 WL 77671, at *1 (M.D. La. Jan. 6, 2015); Rembrandt 
Vision Techs., L.P. v. Johnson & Johnson Vision Care, Inc., 725 F.3d 1377, 1381 (Fed. Cir. 20138). 
     Courts evaluate four factors to determine whether a  disclosure failure was harmless: “(1) 
the importance of the evidence; (2) the prejudice to the opposing party of including the evidence; 
(3) the possibility of curing such prejudice by granting a continuance; and (4) the explanation for 
the party’s failure to disclose.” Tex. A&M Rsch. Found.  v. Magna Transp., Inc., 338 F.3d 394, 
402 (5th Cir. 2003). This test receives holistic consideration—not a mechanical numeration of 
the factors on each side of the balance. See Klein v. Fed. Ins. Co., Nos. 7:03-CV-102; 7:09-CV-094,

2015 WL 1525109, at *3 (N.D. Tex. Apr. 6, 2015) (quoting Hoffman v. L&M Arts, No. 3:10-CV- 
953, 2013 WL 81578, at *3 n.7 (N.D. Tex. Jan. 8, 2013)). District courts have discretion on this 
issue. See Harris v. Amoco Prod. Co., 768 F.2d 669, 684 (5th Cir. 1985). 
     ANALYSIS 
     Defendants  contend  that  despite  repeatedly  asking  Plaintiffs  to  conform  their  Rule 
26(a)(1) initial disclosures to the Rule’s requirements, they still have not done so. ECF No.  148 
at 5. And similarly, Defendants argue Plaintiffs’ Rule 26(a)(2)(C) nonretained-expert disclosures 
do not comply with the Rule despite repeated notifications. Jd. Thus, Defendants request this 
Court  strike  the  noncompliant  disclosures  or  order  disclosure  under  Federal  Rule  of Civil 
Procedure  37(a)(3)(A)  and  37(c).  Id.  at  22.  And  Defendants  ask  the  Court  to  prevent  the 
Plaintiffs from presenting evidence from anyone but individuals who have already been deposed. 
Id. The Court will take each allegedly deficient disclosure in turn. 
     I. Plaintiffs’ Initial Disclosures 
     Defendants argue Plaintiffs’ Rule 26(a)(1) disclosures should be striken. ECF No.  143 at 
10. They contend that Rule 26(a)(1)(A)(j) requires the name, at least, of witnesses the disclosing 
party  may  use  to  support  its  claims  or  defenses.  Jd.  Instead,  Plaintiffs,  in  their  second 
supplement, disclosed the “[c]urrent and former agents, employees, and custodians of record for” 
108 entities and organizations. ECF No.  143-5. Plaintiffs seem to believe they “may use” these 
thousands or tens of thousands of individuals. FED. R. CIV. P. 26(a)(1)(A)(i). Defendants note 
these broad disclosures mean they “have no way of knowing which of these hundreds of other 
mostly undisclosed individuals will actually be giving evidence in this case” and that “this is not 
actual disclosure of witnesses that Plaintiffs may use to support their claims,  rather it is an 
attempt to avoid such disclosure in favor of an avalanche of companies and names.” ECF No. 
143 at 11.

     Plaintiffs see no problem. They argue that Rule 26(a) imposes no cap on the number of 
witnesses. ECF No. 145 at 5. They note that complex cases require complex discovery. Jd. at 5-6. 
And, in any event, Plaintiffs argue that Defendants “know these witnesses” anyway because 
they “employed” some and “deposed dozens in other litigation.” Jd. at 6. Thus, Plaintiffs taunt, 
“Defendants’ feigned confusion is disingenuous.” Jd. They accuse Defendants of confusion about 
the difference between initial disclosures and pretrial disclosures while they contend Defendants 
could go through the list of thousands of people and “decid[e] whom to depose.” Jd. at 7. Finally, 
Plaintiffs interpret their initial disclosures  as only identifying corporate entities. Jd.  at  7-8. 
Thus,  they note,  their initial disclosures only disclose the “representative” of these corporate 
entities. Jd.  at 8. Instead, they argue, it is up to Defendants to figure out who Plaintiffs are 
disclosing as witnesses. Jd. at 8 (“Defendants have multiple tools if they want specific names... 
They have used none.”). 
     The text of Rule 26(a)(1)(A)(i) easily resolves this dispute. It requires a disclosing party to 
“provide  to the other parties...  the  name...  of each individual likely to have  discoverable 
information—along with the subjects of that information.” FED. R. Crv. P. 26(a)(1)(A), (a)(1)(A)QG) 
(emphasis  added).  Plaintiffs  did  not  do  that.  Instead,  they  disclosed  “[c]urrent  and  former 
agents, employees, and custodians of record” for 108 entities and organizations. ECF No. 143-5. 
That is little more than a placeholder for all individuals who worked for or represented those 
entities. And courts “routinely” reject such vague and “broad categorizations of witnesses” in 
disclosures.  Dykes  v.  Cleveland Nursing &  Rehabilitation  Center,  No.  4:15-CV-76,  2018 WL 
3058870 (N.D. Miss. June 20, 2018). That is for good reason. Sweeping disclosures of this sort 
undermine Rule 26(a). Rule 26(a) exists so a nondisclosing party can access the information the 
disclosing party may use to build its case and probe it. See Joe Hand Promotions, Inc. v. Chios, 
Inc., 544 F. App’x 444, 446 (5th Cir. 2013) (‘The basic purpose of Rule 26 is to prevent prejudice

and surprise.” (internal alterations and quotation omitted)); Fielden v.  CSX Transp., Inc., 482 
F.3d 866, 871 (6th Cir. 2007) (“Rule 26(a) generally serves to allow both sides to prepare their 
cases adequately and efficiently and to prevent the tactic of surprise from affecting the outcome 
of the case.” (internal alteration omitted)); Russell v. Absolute Collection Servs., Inc.,  763 F.3d 
385, 396 (4th Cir. 2014) (“The purpose of Rule 26(a) is to allow the parties to adequately prepare 
their cases for trial and to avoid unfair surprise.”). 
     But  these  purposes  are  meaningless  if  the  disclosing  party  provides  deficient 
information. Rule 26(a) requires, except in one noted circumstance addressed next, the name of 
those with potential information for discovery.  And even if Plaintiffs are sti/] unsure of who 
these individuals are, that is no excuse. See FED. R. CIV. P. 26(a)(1)(E) (“A party is not excused 
from making its disclosures because it has not fully investigated the case... .”). Nor can a party 
offload its Rule 26(a) obligations by telling a nondisclosing party to use its own “multiple tools” 
to get “specific names” when the disclosing party appears unable or unwilling to do the same. 
ECF No. 145 at 8. 
     Plaintiffs  attempt  to  frame  their  disclosures  as  an  exception  to  Rule  26(a)’s 
requirements. Instead of the “[c]urrent and former agents, employees, and custodians of record” 
for  the  entities,  Plaintiffs  argue  they  were  only  trying to  disclose  the  “representatives”  for 
“corporate  entities.”  ECF  Nos.  143-5,  145  at  7.  Plaintiffs’  reframing  attempts  to  use  an 
interpretation  of  Rule  26(a)’s  requirement  that  disclosures  have  a  “name.”  Courts  have 
established that when a disclosing party means to disclose a corporate person and not a natural 
person, then disclosing an unnamed corporate representative of that entity meets Rule 26(a)’s 
requirement in narrow circumstances. See Spence v. Am. Airlines, Inc.,  775 F. Supp.  3d 963, 
973-74 (N.D. Tex. 2025). However, this is not a blanket end-run around Rule 26(a). It is only 
permissible when the disclosing party (1) “d[oes] not know who within [the entity] ... would be 
well-positioned and available to testify,” (2) the information is “corporate,” and (3) the disclosure

still “put[s] [the nondisclosing party] on notice as to the source of the testimony [the disclosing 
party] intended to elicit and the subject matter of that testimony.” Spence, 775 F. Supp. 3d at 
973. Plaintiffs’ cited case agrees. In Garth v. RAC Acceptance East, LLC, the court held that if a 
disclosing  party  “identifies...  ‘corporate  representatives’  or  other  generic  categories  of 
employees as individuals likely to have discoverable information ... but makes no reference to 
the subjects of that information, such a disclosure is insufficient for Rule 26(a)’s purposes.” No. 
1:19-CV-192, 2021 WL 4432829, at *3 (N.D. Miss. Sept. 27, 2021). In contrast, if a disclosing 
party discloses (1) “the subjects of information,” (2) the “information is corporate in nature,” and 
(3) “could be elicited from any number of corporate representatives,” then a “generic description 
of ‘corporate representatives’ is sufficient.” Jd. 
     This exception makes good sense. The law generally considers corporations persons, too. 
And  if  a  particular  corporate  person  has  discoverable  information—that  any  corporate 
representative could supply—then the disclosing party has provided a “name” for that corporate 
person by listing it and disclosing a “corporate representative” for that entity.  But notice the 
narrowness.  The  information  must  be  corporate  information—not  information  that  an 
individual who works at that corporation alone has. See Garth, 2021 WL 4432829, at *3 (the 
information “could be elicited from any number of corporate representatives”). And generally, 
the  disclosing party  must not know  “who would  be well-positioned and  available to testify” 
within  the  corporation.  Spence,  775  F.  Supp.  3d  at  973.  Finally,  the  disclosing party  must 
identify “the subjects of information” the corporate person has. Garth, 2021 WL 4432829, at *3. 
And lest the exception be interpreted too broadly still, Spence clarifies that best practice is to 
inquire with the corporate entity who should be named as the corporate representative before 
simply disclosing a “corporate representative” for an entity. See Spence, 775 F. Supp. 3d at 973 
(holding a disclosure “sufficient to put [the nondisclosing party] on notice as to the source of the

testimony” when the disclosing party contacted the third-party entity to determine who should 
be named and ultimately naming “the two individuals [the third-party entity] confirmed would 
be willing to testify as corporate representatives’). 
     Plaintiffs’ disclosures miss the mark to satisfy this corporate exception. 
     First,  they are  not naming only a corporate person with  no concern for which of its 
representatives  testify.  Instead,  they  broadly  gesture  to  all  [c]urrent  and  former  agents, 
employees,  and  custodians  of record”  for  the  entities.  Of course,  far  fewer  individuals  are 
authorized to speak as an entity’s representative than every current or former employee of that 
entity.  If Plaintiffs intended to disclose a corporate person,  they could have  said so.  Rather, 
Plaintiffs’  disclosures  name every current or former agent or employee of 108 entities.  That 
reveals  Plaintiffs  were  not  naming  corporate  persons.  They  were  naming  all  persons  ever 
associated with those entities. That far exceeds Rule 26(a)’s bounds. But Plaintiffs did not stop 
there. They also disclosed all “[c]urrent and former agents, employees, and custodians of record” 
for “any of [the entity’s] affiliates, parents, or subsidiaries.” ECF No.  143-5. Such breadth does 
nothing to  accomplish  Rule26(a)’s  purposes.  The  number of individuals  is  not the  problem. 
Contra ECF No.  145 at 6 (“Rule 26...  plac[es]  no cap on potential witness numbers.”). The 
problem is that nobody—not even Plaintiffs—know who these individuals are and no way of 
knowing exists based on Plaintiffs’ disclosures. 
     Second, Plaintiffs do not provide sufficient detail about the subject of information each 
entity has. Usually, the disclosures identify the entity as an event producer or gym that may 
have information about “Defendants’ anticompetitive practices and collusion.” ECF No.  148-5. 
This  is  an  antitrust  case  where  Plaintiffs  allege  Defendants  engaged  in  anticompetitive 
practices. Thus,  this disclosure is akin to the disclosing party in Garth stating the disclosed 
entities may have “knowledge regarding Plaintiffs claims.” Garth, 2021 WL 4432829, at *4. And 
there the court held such general subjects “insufficient.” Jd. For most other disclosed entities,

Plaintiffs identify them as a gym “that did not return fully or partially to [Plaintiff] events” and 
thus may have information about Plaintiffs’ claims. Rule 26(a) disclosures should help orient the 
nondisclosing party’s discovery efforts. Disclosing potentially thousands of unnamed people that 
may have information about Plaintiffs’ claims in general does virtually nothing to accomplish 
Rule 26(a)’s purpose. 
     And Plaintiffs’ claims that Defendants’ cases only concern “eve-of-trial ambushes” miss 
the point of Rule 26(a) and misread the cases. ECF No. 145 at 6. In Dykes, the court held that 
the disclosing party’s Rule 26(a) disclosure that had “broad categorizations of witnesses” was an 
insufficient  disclosure  to  bring  some  of those  unnamed people  as  trial witnesses.  2018  WL 
3058870,  at  *3-4.  That makes  sense—proper  adherence  to  Rule  26(a)  guards  against  such 
surprise. Watts v. 84 Lumber Co. similarly held that Rule 26 prohibits unnamed witnesses from 
testifying even though they may have been included in “vague and boilerplate identification” in 
a Rule 26(a)  disclosure.  No.  14-CV-327,  2016 WL  7732936,  at *1—-2  (S.D.  Ill.  Feb.12,  2016). 
Finally, McKnight v. Hagel again barred witness testimony from an individual “not identified” 
in initial disclosures or supplements, though ostensibly included in a broad, vague category. No. 
14-CV-1214,  2015 WL  11438190,  at  *3  (S.D.  Cal.  June  25,  2015).  Instead of distinguishing 
between “initial disclosures” and “eve-of-trial ambushes,” like Plaintiffs would like, Rule 26(a)’s 
initial disclosures prevent “eve-of-trial ambushes.” ECF No. 145 at 6. 
     Thus, Plaintiffs failed to disclose under Rule 26(a). Rule 37(c)(1) states that they are not 
allowed to “use” any undisclosed “witness[es] to supply evidence on a motion, at a hearing, or at 
a trial, unless the failure was substantially justified or is harmless.” Plaintiffs bear the burden 
here to demonstrate that their failure was substantially justified or harmless. See Sightlines, 
2015 WL 77671, at *1. Plaintiffs gesture that Defendants “seek unprecedented relief.” ECF No. 
145 at 8. But Defendants only seek relief the Federal Rules of Civil Procedure contemplate. And 
Plaintiffs present cursory argument on the four factors the court should consider to determine 

                                     10 

whether  Plaintiffs’  failure  was  harmless.  But  they  do  note  that  Rule  26(e)  permits 
supplementation. ECF No. 145 at 9. 
     Plaintiffs’ failure to disclose was not substantially justified because their errors were 
repeatedly highlighted, as discussed. And Plaintiffs may not lay claim to Rule 26(e)’s safe-harbor 
clause  because  Defendants  have  repeatedly highlighted,  as  discussed,  how  Plaintiffs’  initial 
disclosures  were  “in  some  material  respect...  incomplete  or  incorrect.”  FED.  R.  CIv.  P. 
26(e)(1)(A). However, considering the four factors the Court must, Plaintiffs’ error is harmless at 
this juncture.  First,  some of the entities  Plaintiffs  name likely have important information. 
Varga v. Wells Fargo Bank, N.A., No. 4:17-CV-265, 2019 WL 13080220, at *2 (N.D. Tex. Dec. 23, 
2019) (“The Court has no doubt that at least some of the testimony of the [un]named witnesses 
is important... .”); ECF No.  145 at 9 (limiting witnesses to those deposed would “assumingly 
devastat[e] Plaintiffs’ case”). Plaintiffs should have an opportunity to disclose properly named 
individuals  or  a  corporate  representative  from  those  entities.  Second,  if  Plaintiffs’  initial 
disclosures stood as-is, then Defendants would be “severely prejudiced” in their “ability to defend 
themselves  against Plaintiffs’ claims.”  ECF No.  143  at  22.  But that prejudice  can  be cured 
through  striking  all those  unnamed in the  initial disclosure  and  granting  a  continuance,  if 
needed, once Plaintiffs properly disclose.  Finally,  Plaintiffs do not explain why they failed to 
disclose properly, except for a misunderstanding of how to disclose entities. That confusion has 
existed in other cases, so this factor cuts in favor of Plaintiffs. See Jones v. Realpage, Inc., No. 
3:19-CV-2087,  2020  WL  6149969,  at  *2-5  (N.D.  Tex.  Oct.  19,  2020).  Thus,  a_  holistic 
consideration reveals Plaintiffs’ error is yet harmless. See Klein, 2015 WL 1525109, at *3; Tex. 
A&M Rsch. Found., 338 F.3d at 402. 
     Accordingly, the Court STRIKES Plaintiffs’ Second Supplemental Rule 26(a)(1) Initial 
Disclosures for all entities that Plaintiffs disclose all “[c]urrent and former agents, employees, 
and custodians of record.” All named individuals remain. The Court ORDERS supplementation 

                                     11 

under Federal Rule of Civil Procedure 26(e)(1)(B) to allow Plaintiffs to disclose any additional 
individuals or corporate representatives they wish under Rule 26(a)’s requirements as explained 
in this Order. Plaintiffs must supplement within seven days of the date of this Order. 
     II. Plaintiffs’   Nonretained Expert Disclosures 
     Defendants challenge Plaintiffs’ nonretained expert disclosure of their entities’ owners 
(‘Owners’) for violating Rule 26(a)(2)(C). They first argue that the Owners are not proper expert 
witnesses  because  they  are  primarily fact witnesses  who would  testify  based on  their own 
experiences and observations.  ECF No.  1438 at  12-19. This, in Defendants’ minds, is a “bold- 
faced attempt to circumvent the Federal Rules of Evidence and unfairly prejudice the jury.” Id. 
at  15.  Defendants believe  the  Owners  are  not proper experts  because  Plaintiffs’  disclosures 
reveal  that  the  “testimony  to  be  proffered  by  the  Owners  is,  by  definition,  lay  witness 
testimony.” Jd.  at  14. And Defendants walk through the minutiae of the Owners’ deposition 
testimony  to  support  their  argument  that “Plaintiffs  intend  to  utilize  the  Owners  to  inject 
unidentified hearsay statements and to make sweeping, unsupported generalizations that are 
several steps removed from their first-hand knowledge.” Jd. at 15. 
     However, Defendants decline—at this juncture—to challenge the Owners’ designation as 
experts under Daubert and its progeny. See ECF Nos.  143 (making no Daubert argument nor 
citing to its factors while seemingly challenging the Owners qualifications and methods), 145 at 
10 (“Defendants’ motion reveals its confusion. Although styled as a motion to strike inadequate 
disclosures, it sometimes reads like an incomplete Daubert motion.”),  148 at  10-11 (rejecting 
that this is  a Daubert challenge because “there  should be  no need to engage  in even more 
expensive expert discovery and Daubert motion practice where, as here, the disclosure of the 
Owners as ‘experts’ is facially improper”). Instead, Defendants attempt to fold a Daubert-like 
challenge into a motion to strike for improper disclosures and then claim that other courts do 

                                     12 

the  same.  ECF  No.  148  at  11.  Alternatively,  Defendants  challenge  the  nonretained  expert 
disclosures themselves. ECF No. 143 at 20-21. They claim that the disclosures merely reference 
the topics the Owners may testify about but neglect to enumerate their opinions and the factual 
bases for them as Rule 26(a)(2)(C) requires. See id. at 21 (explaining the disclosures “boil down 
to a list of high-level topics and legal conclusions’). 
     Plaintiffs highlight Defendants’ odd challenge to the experts’ qualifications,  but their 
declination to make  a Daubert challenge.  ECF  No.  145  at  10.  They  assert that any vague 
Daubert  challenge  is  premature  at  this  stage.  Jd.  So  Plaintiffs  focus  their  response  on 
Defendants’ alternative argument. They argue that Rule 26(a)(2)(C), like Rule 26(a)(1) in their 
minds, “requires minimum detail.” Jd. at 11. And they complaint about Defendants’ “deposition 
tactics.” Jd. at 12. Then they defend the testimonies the Owners gave in their depositions and 
counter Defendants’ characterization of them. Jd. at 12-15. 
     The Court declines to entertain a full Daubert challenge to Plaintiffs’ experts because 
Defendants disavow making a Daubert challenge,  though the Motion sounds in the Owners’ 
qualifications and appropriateness as experts. Defendants’ cite cases they claim indicate that 
courts  sometimes  strike  designated  experts  for  lack  of qualifications  based  only  on  initial 
disclosures do not support their argument. In Dailey v. Vought Aircraft Industries, Inc., the court 
struck designated experts based on a Daubert challenge. No. 3:03-CV-1633, 2004 WL 1068101, 
at *1 (“Defendant’s Daubert Objections”), *3 (striking because the witnesses were “not eligible to 
testify pursuant to Rule 702” and their testimony “is ordinarily fact testimony”) (N.D. Tex. May 
10,  2004);  see  also  Sanders  v.  Waterwood  Natl  Assocs.  LP,  No.  3:09-CV-1940,  2010  WL 
11617979, at *2 (N.D. Tex. Oct. 26, 2010) (ordering Plaintiff to clarify whether its experts fell 
under Rule 26(a)(2)(B) or 26(a)(2)(C); VeroBlue Farms USA Inc. v. Wulf, No. *4, *11—12 (holding 
under Daubert  that “[nJeither Nelson,  Sheriff,  nor Driver is  qualified  as  an expert;  each is 

                                     13 

instead a fact witness... Allowing any of them to present ‘expert’ testimony would violate Rule 
702” and separately holding Nelson and Sheriffs disclosures insufficient). Defendants may still 
challenge  the  Owners  as  experts  under  Daubert  before  the  applicable  deadlines  in  the 
Scheduling Order. 
     But the  Court will examine whether Plaintiffs’ Rule  26(a)(2)(C)  disclosures meet the 
Rule’s requirements. They do not. Rule 26(a)(2)(C) requires a disclosing party to disclose two 
things for each expert not required to have a written report. First, the disclosing party must 
provide “the subject matter on which the witness is expected to present evidence under Federal 
Rule of Evidence 702,  703, or 705.” FED. R. CIv. P. 26(a)(2)(C)G). Second, the disclosing party 
must provide “a summary of the facts and opinions to which the witness is expected to testify.” 
FED. R. CIv. P. 26(a)(2)(C) (i). 
     A “summary of opinions” means “a brief account of the main opinions of the expert, and 
that the opinions must state a view or judgment regarding a matter that affects the outcome of 
the case.”  Tidwell v.  Gomez, No.  5:19-CV-179,  2022 WL 20686845,  at *2 (N.D. Tex. Aug.  12, 
2022) (quoting Tolan v.  Cotton, No. H-09-1324,  2015 WL 5332171, at *6 (S.D. Tex. Sept.  14, 
2015)). Referencing heaps of background facts but not the “main points” from those heaps the 
expert relies on “does not suffice.” Tolan, 2015 WL 5332171, at *6 (quoting Little Hocking Water 
Assoc., Inc. v. EI. DuPont de Nemours & Co., No. 2:09-CV-1081, 2015 WL 1105840, at *9 (S.D. 
Ohio  Mar.  11,  2015)).  The  Rule  requires  clear,  concise  opinions  that  express  the  expert’s 
judgment and the facts connected to those opinions. Fewer, clearer words in these disclosures 
are better and wiser than dumps of potential testimony topics. That is so “an opposing party has 
some notice of what an expert witness who is not retained or specially employed will testify 
about.” Galvez,  575 F. Supp.  3d at 756. The Rule does not require stringent detail akin to a 

                                     14 

written  expert  report.  Rather,  a  brief “abstract”  of the  opinions  and  basis  facts  is  enough. 
Everett, 2017 WL 90366, at *2 (internal quotation omitted). 
     Plaintiffs’ Rule 26(a)(2)(C) supplemental disclosures for the Owners say much but do not 
summarize the specific opinions each Owner is expected to provide and a brief recounting of the 
facts  supporting  those  opinions.  For each  Owner,  the  disclosure  states  he  or she  has  been 
involved in cheerleading for “many years”  in varying forms  and thus is “familiar” with the 
industry and its standards and practices. See ECF No.  143-8 at 4. Then, the disclosures state 
that  each  Owner  “will  testify’  about  industry  standards,  the  role  of event  producers,  the 
importance of bids, and that Defendants imposed “restraints” that harm other event producers 
like Plaintiffs. Jd.  at 4-16.  In each paragraph of the Owner disclosures,  Plaintiffs identify a 
litany of topics the Owners “will testify” about. Jd. And to the Court’s best read, Plaintiffs merely 
copy and paste the same paragraphs for each Owner. Far from offering discrete opinions for 
each Owner, the disclosures offer many “topics of testimony.” Everett,  2017 WL 90366,  at *2 
(holding the disclosures must at least “state opinions, not merely topics of testimony’). 
     And, to the extent duplicative opinions may appear in the paragraphs, the disclosures do 
not connect specific facts to those opinions that the Owners relied upon to form those opinions. 
An opinion must “state a view or judgment regarding a matter that affects the outcome of the 
case.” Tolan, 2015 WL 5332171, at *6 (emphasis added) (internal quotation omitted). Plaintiffs 
use many words but offer little clarity. See Carr v. Montgomery Cnty., No. H-13-2795, 2015 WL 
5838862, at *3 (N.D. Tex. Oct. 7, 2015) (‘This summary essentially references all possible facts, 
rather than identifying the particular facts... .”). And that Plaintiffs simply repeated the same 
paragraphs for each Owner reveals that they are  not disclosing summaries of each Owner's 
particular opinions. “It is insufficient for [Plaintiffs] merely to state that [the Owners] may have 
an  opinions:  [they]  must  state  a  summary of [the]  opinions  and of the  facts on which  [the 

                                     15 

Owners] rel[y] to support them.” Galvez, 575 F. Supp. 3d at 756; see also ECF No.  143 at 20 
(“Plaintiffs do not state...  whether  [their ostensible opinions were]  based on any particular 
conversations, written communications, surveys, or other facts or data.”). 
      Plaintiffs are correct that Rule 26(a)(2)(C) disclosures do not require waterfalls of detail. 
See ECF No. 145 at 11. Even a  trickle will suffice. But that trickle must, “at the very least,” set 
forth each expert’s opinions and the facts the expert relied upon to form each opinion. Galvez, 
575 F. Supp. 3d at 756. Plaintiffs’ disclosures do not suffer from a lack of words; they suffer from 
a lack of clarity about the opinions of each Owner and the basis facts supporting each opinion. 
Because  Plaintiffs’  Supplement  to  Expert  Disclosures  for  Heidi  Weber,  David  Owens,  Jeb 
Harris, David Hanbery, and Kendall Hanberry do not provide  a summary of the opinions and 
facts for each, they are deficient under Rule 26(a)(2)(C). These disclosures are STRICKEN. 
      Next, the Court must evaluate whether Plaintiffs error was “substantially justified or 
harmless” under Rule 37(c). “The district court has broad discretion in deciding whether a Rule 
26(a)  violation  is  substantially  justified  or  harmless.”  Everett,  2017  WL  90366,  at  *4. 
“[E]xclusion is not mandatory or automatic.” Brown v. Joseph Cory Holdings, LLC, No. 4:13-CV- 
044, 2014 WL 12585673, at *2 (N.D. Tex. Apr.  1, 2014). Witness exclusion “is a harsh penalty 
and should be used sparingly.” Galvez, 575 F. Supp. 3d at 758 (quoting Wegener v. Johnson, 527 
F.3d 687, 692 (8th Cir.  2008). The Court evaluates the four factors previously discussed.  See 
Primrose Operating Co. v. Natl Am. Ins. Co., 382 F.3d 546, 563-64 (5th Cir. 2004). 
     First,  Plaintiffs argue that the Owners have “[vJital testimony.”  ECF No.  145 at  17. 
However, Plaintiffs appear to be stating that as a general matter. Elsewhere, they indicate the 
testimony as experts is less important because  they “disclosed them  as  non-retained expert 
witnesses  out of an  abundance  of caution.”  Jd.  at  10.  Defendants  only  sought  the  Owners’ 
exclusion as expert witnesses—not lay witnesses. ECF No. 143 at 21. Thus, the first factor cuts 

                                      16 

against Plaintiffs because much, if not all, of the evidence Plaintiffs seek to introduce from the 
Owners could be provided as lay witnesses. 
      Second, Defendants would be quite prejudiced if the Owners could testify as experts to 
all  the  unparticularized  information  in  the  disclosures.  Plaintiffs’  attempt  to  argue  that 
Defendants are not prejudiced because they have already deposed the Owners misunderstands 
the nature of the prejudice. “Defendants have no obligation to remind [Plaintiffs] to comply with 
the Federal Rules” and Plaintiffs’ deficient disclosures have “prejudiced Defendants” because a 
“proper expert designation  allows opposing counsel to  anticipate  the expert's testimony and 
make decisions about how to approach that expert.” Carr, 2015 WL 5838862, at *4. 
      However, third, discovery is not yet closed, and continuances remain available to cure 
any prejudice if Plaintiffs manage to disclose properly the Owners as nonretained experts. The 
Court  can  order  supplementation  to  give  Plaintiffs  one  final  opportunity  to  meet  Rule 
26(a)(2)(C)’s requirements. 
      Finally, Plaintiffs offer  a meager explanation for their failure to disclose but note that 
“reasonable  minds  differ on  disclosure  requirements.”  ECF  No.  145  at  17.  Considering the 
factors “holistically,” and noting the closeness of the inquiry, the Court declines to prohibit the 
Owners from being nonretained experts. “Although striking” the Owners as expert witnesses “is 
an available option under Rule 37, this is a harsh penalty that the Court does not choose to 
implement at this time.” Sanders, 2010 WL 11617979, at *3. A “less severe remedy will largely 
cure any prejudice that defendants suffered due to [Plaintiffs] noncompliance.” Galvez, 575 F. 
Supp. 3d at 758. The Court instead ORDERS supplementation of the Owners’ expert disclosure 
under  Rule  26(e)(1)(B)  to  comply with  Rule  26(a)(2)(C)’s  requirements  as  explained  in  this 
Order.  VeroBlue, 2023 WL 348016, at *9. Plaintiffs must supplement within seven days of 
the date of this Order. 

                                      17 

     CONCLUSION 
     Accordingly,  Defendants’  Motion  is  GRANTED  in  part.  The  Court  STRIKES  the 
noncompliant disclosures and ORDERS supplementation under Rule 26(e)(1)(B) of the Rule 
26(a)(1) and Rule 26(a)(2)(C) disclosures as explained in this Order. All supplementations must 
occur within seven days of the date of this Order.
