I've said it before and I'll say it again. Kraft f**ked up massively in his "concession speech". That speech is one of the primary things the haters and even non-hater anti-Goodellites point to when they say "well, something probably happened". Because they say -- not unreasonably -- "why did he lie down like a gutless dog if they were really innocent?"
I'm not saying he should have gone on some damn fool idealistic crusade. All he needed to do was:
1) Invoke whatever appeal process there is (the same one the Chargers used in Towelgate). I concede it would have accomplished nothing, but it needed to be done.
2) Phrase the key part of his concession speech more like this: "The team did nothing wrong. Tom did nothing wrong. As such, I was planning to challenge the team punishment in court. However, our attorneys tell me that any such challenge would be futile and in fact could result in more penalties levied against the team as punishment for the act of challenging. Therefore I am, very reluctantly, choosing not to challenge this grossly unfair punishment at this time."
3) Not a single mention of the Other 31.
