The more this plays out the fewer games I think he'll actually start.
He did nothing to earn the job for next season, and there's really no reason to believe he can win a QB competition in camp...so yea
Then you have his immaturity, and the fact that the Browns will prolly trade him if given the chance, but who will want to trade for him?
The NFL is very good at accepting off the field distractions and problems if you're a good enough player for the effort. If you're not, well you get ushered out of the league pretty fast. Nobody wants a backup QB circus.
