If you are rebounding against someone who is taller than you or can jump higher, tip the ball away from your opponent to gain an advantage. The extra inch you get with just using your finger tips instead of trying to grab the ball with your hands could completely eliminate your opponents height advantage.
technique works especially well for guards rebounding against big men. If you
can just get your finger tips on the ball and tip it away from you opponent,
this will move the ball to an area more likely for you to grab it.
