What's the biggest stylistic difference between you and Jim Harbaugh?
DS: We're different personalities, but the core composition is the same: We both have football-coach fathers, and we understand that it's all about trying to win every day. One thing that defines me is that I'm very direct with people.
SI: WHAT'S ON YOUR NIGHTSTAND?
DS: THREE BOOKS: A BIO OF ABRAHAM LINCOLN, ANOTHER ABOUT THOMAS JEFFERSON—MY TWO FAVORITE PRESIDENTS—AND THE GREATEST SALESMAN IN THE WORLD. I'VE READ IT 10 TIMES. IT'S INSPIRATIONAL.
What would your players be surprised to learn about you?
DS: The span of my music collection. My iPod [includes] Jay-Z, Sade, Kenny Rogers, classical music. When I feel like grunge, I have Stone Temple Pilots on call. Sometimes I want Mozart.
You participated in track and basketball in addition to football at Stanford in the early '90s. How did you manage that?
DS: I joined track to work on my speed at shorter distances. They talked me into running the 400, which was masochistic. I joined the basketball team to help them practice because they had nine guys. Against Oregon State we were winning big, and coach [Mike] Montgomery put me in. I have one NCAA stat, a rebound.
