Obviously when you take Rachal as the top guard in the 08 draft and Carl Nicks isn't taken till the 5th, and Sitton from the Packers is a 4th rounder that year, I think you can never tell who is going to be the best guard out of a draft class.
People like to look back and say that scouts called him raw back then but I highly doubt that they did(I mean compared to nicks and sitton he was deemed more day 1 ready). What I read was that he was seen as a mauler who could immediately contribute because he "faced elite talent in the Pac 10". He had a few injuries in college, but he still rocketed up draft boards because of his elite size.
DeCastro looks promising, but he's still a prospect and you never know how well he's going to perform. Lucky for him it seems he's at least entering a pretty good situation in Pittsburgh.
