Jobs are hard to come by, so players are extremely motivated to do whatever it takes to keep their job.

Veterans get priority in the training room and better parking, but there is not a whole lot of difference in terms of how they're treated in the competition for playing time. To me it doesn't matter if a guy is a 10-year veteran or a rookie. If the rookie is better, he finds his way onto the field.

I learned through apprenticeship. I was an assistant to a defensive coach, and I'm still learning.

I didn't play in the NFL, and I didn't play defensive line. But football, at the fundamental level, is football. It's about motivating people and getting the best out of them.

More often than not, you find players seeing something that they can help another player with or reinforce something the coaches are seeing. Veterans do that regularly with younger players.

There is a great amount of precision within each individual's technique and role in the play. When you put 22 of them out there, it can look chaotic but when you break down individual performance, it looks less so.

The best coaches I've been around, even older guys, are continually learning new ways to do things and new ways to teach.
