Here's the thing: I believe he WILL show. But there are levels of the kind of showing he can make. What he SHOULD do is publicly stand, acknowledge the crowd, take his well deserved booing and move on.
What I expect he WILL do is secret himself into some luxury box, ignore the fans, and after one quick shot of him to prove he actually did show up, never be spoken of again. BTW- 100% guarantee that he is long gone from Gillette when the final gun sounds.
That being said, IFFFFFFF a full blown clown out ever starts to take shape, the odds of him coming will begin to shrink. It is one thing to be the subject of a couple of minutes of booing at the start of the game, and entirely different thing to be publicly humilated for 3 hours straight in front of a national TV audience. Go CLOWN OUT.
