If you go back to the early part of his career, he was the bright spot on a defensive backfield that was quickly losing its luster (as all of the previous stars departed for the NFL). So, when he nabbed an INT or recovered a fumble - as he did with L'ville - it stood out in relief. Just the same, when he couldn't make a tackle, he got all of the blame. Meanwhile, where were any of the other defenders?
I agree with others above -- he played too early, was a victim of a (couple of) coaching changes, and now .. injury. I think that if he were a freshman today, he'd have a much brighter future.
