He is very steady. He very rarely makes a mental error. I think he improved all spring.
At spring practice, he sat us down and told us what he is about; he told us what's important in his life and how important the players are to him. He was the only coach I had that told us he loved us.
I'm just trying to emphasize the fundamentals of gap control. Take care of your assignment and then run to the football. Bottom line is you want to take the shortest route to the ball carrier and arrive there in a bad mood.
I played like that. Defense has to be an exciting thing. I think there's a lot of ways to score on defense and I try to emphasize that.
