Bill Belichick on a life in football

You're probably thinking the same thing I was when I sat down with Bill Belichick: What's going on with his sweatshirt? "Well, you could see I've worn this one for a while," he laughed.

Tattered and often sleeveless, Belichick's signature look is part of his singular focus. As he writes in a new book, "The Art of Winning" (to be published May 6), he's motivated not by style or fame, but by the obvious. "I try to capture some of the ups and downs and the preparation and the dealing with star players and the big moments," he said.

"You wanted to give back to football, you write, some of what football has given to you?" I asked.
