The problem with Manziel was that he was a total screw-off.
Out partying most nights and didn’t know the playbook when he was tabbed to start late in the season.
Unforgiveable at the NFL level.
Supposedly he got sober in rehab over the winter and is making strides, but is now on the bench with a bad throwing arm. Technically he should be a Sr. in college this season, so maybe maturity will come with age.
True, and that doesn't help. But it's not exactly knew. I seem to remember some successful QBs having to get bailed out of jail for the game by their coaches.
