Many will not want to hear this but if you watch his OSU film, you see a kid who throws to easy targets. Don't get me wrong, I'm not trying to say they weren't good or accurate or anything else. I'm saying that if you go to play QB at a school like OSU, you aren't really forced to develop certain skills. You are, more times then not, throwing to the very best WR talent, being protected by the best OL talent, being supported by the best running game and probably playing with a lead because you have the best Defensive talent in the country, most times, rather then playing from behind and that talent goes three deep. You don't learn to throw into tight windows or make quick reads. You get away with mistakes you wouldn't be able to if you played at a school who wasn't as talented.
You kinda see the same thing at Alabama. That's my take on it.
