Your lack of basketball understanding truly knows no bounds.
It's obvious you've never boxed someone out, nor even can differentiate a good rebounder from a bad one.
Tell you what; you get on the low block in an NCAA game, or even your nearest men's league...when the shot goes up don't "run or jump." Just stand there...you will find yourself sitting underneath the basket with empty hands.
Whether or not you understand it, there is skill involved regarding one's positioning, their center of gravity, the timing of their jump, their hands (both rebounding the ball, coming down with it, and holding onto it), etc. If you can't see that, I don't have anything else to say to you.
You've made it painfully obvious, but your posts get are getting progressively worse. Just take a break for a bit...it appears that 99.9% of this board really can't understand a single point you attempt to argue.
