I've never valued material things. I've always been more attached to people. The pursuit of material things takes time, and I realized my time is very valuable especially during the season. My time with my kids, what I do to take care of my body, and of course any intellectual pursuits I may have on the side. Those are all things that I value.
I think with defense especially, you have your core principles. If you do those consistently, then it's easy to make, sort of, game-to-game adjustments. But, when you're not doing your core principles consistently, you end up just guessing a lot. To be honest with you, that's what bad teams do.
