Duncan was literally unique and comparisons should be avoided in all cases. I stayed up until midnight to watch his first game as a Deacon in the old Alaska shoot-out tournament against Alaska-Anchorage. Childress was sick and didn't play and we lost - to Alaska-Anchorage. IIRC, Duncan didn't score. I am no basketball guru but I came away from watching that game knowing he would be special. It is hard to describe if you didn't see it but it was obvious. The footwork, the way he kept his hands high on defense and caught the ball high off rebounds, his timing on shot-blocking, the way he caught anything that came near him... It all just looked like it came naturally and easy to him.
