How hard does he have to smack it? If he taps it is it ok? Still having nothing to do with basketball?

Ask yourself the question...

Why did the player purposely slap the backboard?

Understood. I think you realize that my comment was more in reference to asdf's characterization of this play, but you are right more generally speaking it does matter.

T

Habit, routine, to show off who knows? Do you penalize when a player crouches down and slaps the floor when he gets in a defensive stance? Why do you think they do that? The rule gives you authority to penalize the backboard slap, but not just because you thought it was a non-basketball play - if you deem that he did it for unsportsmanlike purposes then it must be so hard that it cannot be ignored or to vent frustration (cb 10.3.4)

There is no reason for a player to purposely contact the backboard.

None, zero, nada, zilch......

It's only done to draw attention to himself. You leave that go, and his opponent now is gonna one-up him.....then he's gonna one-up him.....

When you gonna whack someone? Where do you tell the coach, who has seen it now twice unpenalized, the threshold is for purposefully slapping the board to hard or too loud?

Whack it when it first happens. If it happens again, you have set the threshhold....

Finally saw video. Easy 'T'.

If he hung on to the rim long enough to slap the backboard, he deserved it. Good call, but I did have to watch it twice!

agreed
 

T - No question. What ever happened to calling the T for pulling the rim down? Every dunk I see now, regardless if there is even another player in the front court, the dunker pulls the rim down. I quit calling T's after I was written up for "overofficiating" it. In my oppinion he could have been T'd up for hanging - the slap was automatic.

Pulling the rim down does not warrant a technical foul. The rim collapsed becasue it's designed to do just that.

Now, hanging on it or performing a "pull up", that's different.
