He is very good at fighting off blocks. On almost every single snap, he would chuck-off the o-lineman and either make the tackle or chase the play. Rarely did I see him stuck on a block. The guy has a rare ability to fight off blockers in the trench, and is very aware of the action around him. I'm sure he was a major factor in LSU's strong performance against the run this year.
Big negative is that he's got some character issues and never reached his "potential" at LSU. And he's apparently an extremely cocky loud-mouth. But I'm looking forward to him develop as a 3-4 end. His ability to shed blocks should be a valuable skill in the NFL.
