Even if the Texas are frustrated with him, it's his first year in the league. He is young and has dominated since he first started playing football.
It may take him a few years to learn how to be a professional, but when not IF he does the dude is going to be a monster!!!! And by professional I mean doing all the little things, practicing hard playing hard etc etc...
He has jj watt to help him Learn along the way. There is no way that some of watts work ethic will eventually rub off on clowney.
