Section 6Burden of Proof
The failure by a Club or Clubs to negotiate, to submit Offer Sheets, or to sign contracts with Restricted Free Agents or Transition Players, or to negotiate, make offers, or sign contracts for the playing services of such players or Unrestricted Free Agents, shall not, by itself or in combination only with evidence about the playing skills of the player(s) not receiving any such offer or contract, satisfy the burden of proof set forth in Section 1 above. However, any of the types of evidence described in the preceding sentence may support a finding of a violation of Section 1 of this Article, but only in combination with other evidence which, by itself or in combination with such evidence, indicates that the challenged conduct was in violation of Section 1 of this Article. Nothing in this Agreement shall preclude the NFL or its Clubs from arguing that any evidence is insufficient to satisfy the burden of proof set forth in Section 5 above. Nothing in this Agreement shall preclude the NFLPA or any player from arguing that any evidence is sufficient to satisfy the burden of proof set forth in Section 5 above, except as set forth above.
