IIRC , half his sacks came from some bottom feeder SEC team and a FCS (I-AA) teams. Most NFL DEs are a lot taller to match up with Ts or TEs. The only moderately successful DE his size is Baltimore’s Elvis Dumervil and he is alot heavier. Not so sure his first step will help him against even RTs let alone LTs in the NFL.
And, I don't think anyone believes he has the speed and agility to take on a good TE in pass coverage.
I was essentially neutral on his NFL prospects and thought he might have a future on special teams.
But since the cake-in-the-face kiss, and the Oprah documentary, and his claim that he should have been drafted in the 2nd or 3rd Round, well, I will quietly smile if he's a complete failure.
