The NFL has a very short memory for first offenders. Vick, R. Lewis, Burress, Stallworth, Jamal Lewis, Moss, and on, and on...
He'll get a chance either by the end of the season or next. If a team is making a playoff push and their RB goes down, he'll get a call.
I wouldn't be surprised if his agent hasn't gotten calls already. If he's in shape, I could easily see teams with good PR departments taking a low cost flier. Cowboys, Patriots, Jets, Falcons, Bucs....teams always need good RB's.
