I still don't like that he does not have that killer mind set. I saw on one play where he had a chance to blow up the RB and he let up and the guy got an extra yard on the play. His nose for the ball is uncanny but he does not like to destroy players.
He popped Greene several times. Not every tackle is a madden hit stick bro. He had 10 tackles in 1 half. No need to nit pick about him hitting harder. The thing about Luke once he gets his hands on the guy they go down almost every time. The play is over once he's there.
