You see it differently than I do then... I see his press conference as a sign of victory. Did you watch it? Very un-Belichick like. Similar to the Aaron Hernandez press conference - he's clearly bothered by the accusations that his players had an unfair advantage. He also said outright that they tested balls under game situations and found significant fluctuations in the PSI from start to finish, and he then said that "At no time was there any intent whatsoever to try to compromise the integrity of the game or to gain an advantage,"
I read that as a victory speech. I read that as he knows what the NFL knows, and that. at the very least, what the NFL knows proves nothing.
