What do you call here?

Let me make this clear to you and everyone reading this. The amount of vibration on the rim/backboard has absolutely nothing to do with anything. The only thing you have to determine is if any player hit the backboard on purpose to showboat or to purposely vibrate the backboard. If you determine there was attempt to block a shot and they miss the ball, whether they hit the backboard hard is not apart of this call. Vibrating the backboard cannot be goaltending or basket interference considering that the backboard has nothing to do with that call.
