Dude is an absolute freak. Especially in the long term it makes sense to take him over Andre for the age advantage. Matt Stafford if he can live up to his potential and get CJ the rock consistently, he's going to be even more trouble to stop. It's safe to say that both have had their fair share of bum quarterbacks, but Calvin hasn't had anything close (jury is out on Stafford still) to what Schaub is.
