Well I knew Duncan didn't have that high of a vertical. Have you ever seen him play? He has good timimg on his jumps which is why he gets lots of tip dunks, but he struggles to actually dunk. He doesn't get that high off the ground. But his long arms make up for it. I read somewhere his vertical is like 26 inches.
I've known Madsen's vertical for awhile because it told his jump in his profile on nbadraft.net. Go back and look. He has a 30 inch vertical.
Mugsy Bogues used to have a very high Vertical Jump. I heard the guy could dunk. Not sure!! But it's no big deal for Duncan cuz he is so tall and big and an intelligent basketball player. He uses his size and quickness well enough to not need to jump to make his shots.
If mugsy bogues can dunk, I can beat Kobe in 1 on 1. Tim Duncan has no ups. That's true, but, why the hell does it matter? He doesn't enter dunk contests, so what's the big deal? He's 7 ft tall so he can already almost touch the rim! Does he do the tip off or Robinson?
