Well, KO is projected to go as he's one of the best underclassmen linemen in the nation. I think after 2 more years, AK-47 and Knott will go. I think there's an outside shot for Ben Lamak to go this year, but probably as a free agent... and maybe a really far outside shot for A-Rob... but don't hold your breath on that one.
As far as the young talent, we haven't really seen any of it other than a few linemen and the linebackers... so it's hard to say.
Edit: Oh, and Colin Franklin should end up in the NFL somewhere. That kid is a stud.
