I think the big concern is his feet and movement in space.
I still think it is a big step up from Miami (OH) to NFL type competition. I know they aren't Division II or anything but it isn't like they regularly go up against Texas, Alabama or USC either. I would think it would take a bit of time to adjust to the superior competition as a rookie and a year on the bench is very likely.
All I'm saying if he is the draft pick we can't plan on him being ready to start next year. It is a completely different story for the big school guys who will go in the first couple of rounds (DeCastro, Glenn, Osmele, Zeitler) - they will be penciled in as starters next year.
