Michael Jordan would not have been the answer at C. I don't know why you guys wanted him. He even knows he sucks at C and OG is his best position. He has clearly stated that he doesn't want to play C in the NFL. He is too stiff, and slow out of his stance. He never would have beaten Harrison out and even if he did, probably would have gotten Sam killed.
Guard would have been fine. Even if he couldn't beat Harrison out this year doesn't make him a bad pick. Sometimes rookies sit?
