Perryman is the type that will continue to improve.
Even before he bulked up alot, he was the type of LB that when he hit someone, they went backwards. Now he's just inflicting pain.
Plus, his stature helps him IMO. Being a little lower to the ground makes it easier for him to put his hat right on the ball. And it gives him leverage. The only way it hurts is when he's in the passing lane and can't bat it down. But in the NFL, the QB's are good enough to thread it through taller LB's anyway.
I'm loving these LB's we got finally. No more little guys getting abused out there. Same with the DL. We aren't quite back to being dominant on D yet, but we're on our way.
