Again, Duncan was a swimmer, soccer player. Yes, he doesn't jump out of the gym so some people get confused. The guy is as fluid as they come at 7'1. Why he was such a great shot blocker/rebounder.I wouldn't call Duncan unathletic. I just don't think he relies on that to be effective. Is he D. Jordan, B. Griffin, A. Davis, etc in routinely hanging on the rim and quickly getting down the court? No. That's what people mean. He's been great based on savvy, smarts, great footwork & positioning, and sticking with his strengths.
