He's actually shown a lot of improvement, IMO. He's generated quite a bit of pressure...hasn't resulted in sacks, but has flushed the QB multiple times this year and disrupted rhythm. I'll also add that most teams we've faced haven't provided opportunity for a pass rush. Our first opponent was a 3-step quick release offense. LSU generally ran all over us. And Utah was mostly a horizontal movement offense. Corbin hasn't faced much opportunity for a traditional pass rush.
He needs to bulk up quite a bit still. But I think he's going to be pretty good.
