You are only allowed to hang on the rim after a dunk if you are preventing yourself or another player from getting hurt.  But what if you already hurt the other player and he's lying on the ground dead?  Oh wait, Rahim Mama's defender isn't dead.  That's him running around yelling and cursing at somebody.

Rahim is a junior at E.O Smith and if he keeps taking out defenders like this, we might have to keep a closer eye on him.
