"Didn't Bobby Stoops do something like recruiting nothing but fast players and bulking them up to whatever position he needed?"
no. but he did say something like that, but he wasn't talking about lineman. Usually when you recruit somebody you want them to atleast have the chance to play as true frosh, you want that option. most people don't wan't a commit from a guy that is a 2 year weight room project. With the 85 schol limit you can't afford to put a player on schol and keep him tucked away like that for so long.
