However, I think he's selling Woolfolk short. He never struck me as THE liability in the secondary, especially considering that he was asked to pull off a mid season position switch.
A guy that wasn't mentioned is Cullen Christian who was no slouch as a recruit. Dorsey made headlines so he completely overshadowed Christian, but wasn't Cullen considered a better corner whereas Dorsey was a safety?
Michigan's secondary lacks glamour, but I think we have enough stock to find a Tyler Sash and Amari Spievey somewhere in there. Time will tell.
