interesting excerpt:
Q: "Your run with the UCLA Bruins to the NCAA Final Four made you a big name in college basketball. How did that experience shape you as a player?"
A: "Yeah, I would say that team and the group we had at UCLA — the level of basketball we played was so pure. Such pure team basketball. To experience something like that, you remember it. You remember that the game can be played in a very pure way — all to win, all together. That’s what we did and that’s what we had. We made a great run. The pureness of basketball is a very beautiful thing."
