Yeah, this whole "mess off the field" thing is bullshit.
His off the field shit isn't nearly as troublesome as Manziel's. No where near the same league. He had a hot tub in his dorm room and got laid as a result. He wore a "Fuck Trump" hat. He speaks his mind and has a number of good points regarding college athletes; particularly the CTE issue. He had fun with his neighbor's yard furniture.
He is very outspoken about helping those less fortunate than him and actually does something about it. He refuses to be told that he shouldn't express his opinions and is fearless when it comes to calling things as they are. In think he is exactly the sort of leader you want so long as he focuses his energies a little more. You want that sort of brashness and brains.
He has a little growing up to do, but when it comes to his remarks it just seems like he is a bright kid that doesn't have time for people's bullshit. In no way should his behavior scare teams. But, thankfully for the Browns, some NFL execs are stuck in the 50s and would rather have people who beat their wives on their team than someone who might express an actual opinion instead of mouthing bland platitudes.
Provided his shoulder is good I like him even more as a potential franchise QB.
