Well for one he's not screwing around with his dogfighting homies, and that would seem to make him more focused on football. Also he has a mentor (dungy) that he probably desperately needed. I can see him now out of prison, realizing that he isn't superman any more, and wanting to regain his credibility. He fell from his status as a high level player to, well, scum. Now, if our penal system did what its supposed to do (I know... big IF there) then he has realized what he needs to do to get back to the top, and he'll bite on the best chance he has to get back to the top. And I hope thats with the Bills
