Not to take anything away from Suh, but comparing college linemen to their college counterparts won't work. NFL guys have: more weight, more strength, more experience, and - most importantly, more skills. The best coaches and trainers are in the NFL. Even an average NLF lineman would standout on any college team. The guys Suh blew away will mostly never play at a higher level. One college lineman who held his own was Texas Tech's Brandon Carter, and Carter's nowhere near the top OL in the draft.
I'd pick Suh #1, but he won't dominate like in college.
I don't buy your last statement. Suh will prove you wrong. People said the same thing about a certain defensive end that was high in the Heisman voting that ended up in Tampa Bay. Suh is a winner and has the drive.
