After watching Stanford last night I would be happy with Martin or DeCastro. They looked like a couple of studs last night. Other than a LB'er making a pro move on a RB to get to Luck I don't think he got touched while in the pocket.
I thought martin looked good.... but decastro looked like a beast. He moved his guy backwards on every running play, destroyed the edge every time he pulled and didn't allow penetration on passing plays. I don't know what to think about drafting a guard that high but its a big need
