Long-armed knee-bender who can play the role of low man at the point of attack. Plays with strong hands and good arm extension and can “peekaboo” both gaps as he reads which hole the running back heads for. Impressive stack and shed timing and power. Able to eat up double teams and keep his linebackers clean when asked to. Excellent athleticism. Can make plays all along the line of scrimmage. If blocker doesn’t finish, Butler will work himself back into the play. Able to coordinate hands and feet smoothly and has change of direction and closing burst to become a dominant pass rusher from inside. Can slide from gap to gap as a pass rusher and is a perfect fit for twist-based defense. Generally attacks gaps with forward lean and ability to corner the edge when he has his man beat. Can stutter-step into pass rush to disrupt offensive lineman’s timing or generate a speed-to-power bull rush that can severely dent a pocket. Gives consistent effort and plays like a lead dog looking to eat.
