Jameis...just doesn't make sense. He seems to have everything - good arm, size, reads defenses, nice family - but is a complete fuck up. Like seriously, dude seems like he has a 7th grade education at best. And is in a situation where he can do just about anything and get away with it.
Physically he looks like an NFL QB but I'm going to assume he'll be a bust for the same reason Manziel will be: not serious, stupid, won't study, etc.
