when a dude can shine against pro players, you know he will be a solid pro.
throughout his career, manziel does bad against pro players.
He'll be a solid backup in the nFL and get his 4-5 years in the league, he's already set for life, moneywise. He's a winner in life. We don't have to say he'll be a 12 year starter for him to 'win'. Tebow 'won' and he's out of the league with plenty of options now.
manziel might be good enough to work in the pros - BUT he has to do better than he does now. as good as he is... he's underachieving. and he's one clean hit away from being average speed and no longer among the best - arm ain't as good as many, he just pwns the shit out of people with his ability to scramble, they have to keep people close to him, opening up receivers.
