This latest blunder by Goodell sounds exactly like the kind of thing Elliott's lawyers could use in a lawsuit as an example of "procedural mistakes" made during allegation evaluation.

"In a lawsuit, Elliott would be joined by the NFLPA. He would assert that Goodell and his four experts committed grave procedural mistakes in evaluating the allegations and that, accordingly, they reached an arbitrary and capricious conclusion. A federal court reviewing a petition to vacate the arbitration award would focus on procedure, not on facts. Put another way, a federal judge would not conduct a trial on whether Elliott is innocent or guilty of Thompson’s allegations. The judge would instead evaluate the accuracy and credibility of the processes used by the NFL in assessing allegations and whether those processes comported with Article 46."
