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

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

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.

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.

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.

After several years in the league, when a player becomes a vested veteran in the NFL, they play under a different set of rules. For instance, if you cut a vested veteran mid-season and they don't get picked up by another team, you owe them the remainder of their salary.

When teams win and play well, everyone benefits from a financial standpoint. But everyone takes pride in people being able to achieve at that level.
