Re: Aggressive Low Post Defense
You can use swim moves and spin moves to get the rebounding position. Try it from further away from the basket, he won't know what is coming to him. You'll have more speed, use that momentum to get him out of the way. Try the 'tap move' a couple of times too. If he's that physical he'll react to the contact you give him. Those finesse moves will work against a physical rebounder.
If you don't feel like doing that just handcheck the shit out of him or just go over the back in some situations.
Also, stay low. Gives you much better rebounding position.
