A basketball team is like the five fingers on your hand. If you can get them all together, you have a fist. That's how I want you to play.
The thing I loved the most - and still love the most about teaching - is that you can connect with an individual or a group, and see that individual or group exceed their limits.
To me, teamwork is the beauty of our sport, where you have five acting as one. You become selfless.
The truth is that many people set rules to keep from making decisions.
That's what I do now: I lead and I teach. If we win basketball games from doing that, then that's great, but I lead and teach. Those are the two things I concentrate on.
