It won’t be for lack of effort on his part.
I think the biggest thing against him is the public perception of him. Mostly undeserved, IMO.
He had a chance to take a leadership role in Denver, before Elway undercut him.
I thought Jacksonville would have been a perfect fit for him.
Manziel is going to get the same treatment. More for his negative behavoir, but think about this: Manziel goes to some place like Jacksonville, sits on the bench, Jacksonville loses a few games and the crowd starts to scream for Manziel.
