If I were Bill, I'd leave ESPN. He can't be an effective analyst there while being a mouthpiece of their propaganda.
I'd guess that he will leave before too long. He doesn't strike me as the kind of guy that would just lay down and take that if he feels it's unjust.
I really liked his stuff back when he was the BSG on Digital City Boston, and then when he went to ESPN he seemed sort of defanged and declawed for awhile, but slowly, he's been getting back to the less restrained version of who he is, which I personally find far preferable.
I'll be a little surprised if he's still there in a year. Granted, they probably pay him more than anyone else would, but still, I expect he could make a handsome living elsewhere. He's national now, not the youngish regional upstart from Boston. If he feels like his punishment is unjust, I hope he says screw 'em and breaks away.
