Not a big deal, but one more act of "big timing" his Tampa teammates. Publicly they'll say it's cool, he's the goat, yada yada. Privately they're noticing the guy who handles the ball on every play wasn't there for 11 days in the middle of training camp and now isn't there for a walk through. It's one thing if you're trying to save your marriage, another if you're going to New York to party with former teammates.
They also know he's set to leave at the end of the year leaving a huge cap hit, and has a history of negotiating his next deal well in advance with rumors of MIA being in play already being suggested.
Not exactly the same kind of energy they had two seasons ago when they were united to bring home a SB, now it's playing out like it's every man for himself.
That, and, you know, actually using the time wisely and staying focused on preparing for the game rather than flying to NYC, partying, and flying back. It's not like the head coach / GM has loads of time on his hands during a game week.
