Some of this has already been stated, but
Rebounding is about:
1. position relative to shot angle
2. position relative to 'your man'
3. anticipating the angle of the shot
4. quickness to react to the ball
5. vision of the floor
6. jumping ability
7. strength of hands and arms
8. desire to go get the ball
9. number of fouls the player has
10. the luck of the bounce
On our high school team, each week someone was awarded the rebound shirt (there was an assist shirt, too). The 7 footer on our team got it a few times, but at 5'10", I wore the shirt more than he did*. **
*Since we are anonymous here, I guess that I can brag about it.
**I could be lying, but I'm not. In fact, we jokingly called the guy Reuben Rebound!
