Bull crap, with all respects
It seems like he lacks leadership qualities and lives in a perpetual funk of "woah is me". I understand that he's upset he's not the starter, but he also didn't play well enough to be the starter. He wasn't handed the job on his 1st round/1st season laurels, he had it ripped from him for not being able to play the way he wants to play and it crushed him.
The injury destroyed his ability to play the game the way he did in college. He didn't try to adapt and become a better pocket QB and looked completely lost in preseason. Hell, even Tebow worked hard to try and become a better QB. Not to mention his passive aggressive nature doesn't exactly scream "get behind me and I'll lead you to victory". I could be wrong, but he's done. Some team will take a flyer on him, but I don't see him being successful.
