I think the kind of analysis that was in the AEI report would qualify as "new information," but I think all Brady has to do is give Goodell any reason at all to vacate the suspension, including just showing up and being polite.
As you observe, the critical thing is that Brady has to be completely exonerated and not just have his suspension lifted. I don't think that Kessler, the NFLPA or Brady will be in any mood to "compromise" for the very good reason that they don't have to compromise in the matter of Brady's culpability.
I also have the feeling that we might not have heard the last of this from Kraft, who has been updating his anti-Wells web page almost every day.
Had Kraft appealed without the hammer of a threat to take the League to Court, his Appeal would have dominated the news for weeks before being rejected by Goodell earlier this month. As a result, the press would now be all over Brady for the Patriots' not accepting their punishment and continuing to "whine."
Instead, the little press there has been has been in Brady's favor for the last couple of weeks and the focus is completely on Brady's appeal and the nonsense in the Wells report.
