Michael Jordan and I are both @ 6'-5", so why does he have a 48" vertical jump while mine is 18"? The answer is genetics...and white men can't jump!
Good stuff JAD !. I agree genetics can play a big role in things no question about it. However, it is the wrong answer. The right answer is the shorter girl is on PED's. Just kidding.
Seriously, genetics may be part of the equation but not sold on the fact that genetics is the reason the tall girl can't do 1 push-up and the short girl can do 20. Not being able to do one push-up is strength related IMHO and the question is.....which I think others have answered well, is that getting the girl stronger could or should help with her velocity.
Both girls are completely fictitious by the way and nobody was harmed in the making of this thread
Lastly, I am confident I could increase your vertical at least by an inch..... Thanks for the reply as always JAD and go DUKE!!!!!
