Backboard slap

[jodibuck]

In a j.v. basketball game, we had a fast break lay up, defensive player from behind slaps backboard trying to block shot. Ball does not go in. I make no call. The officials for the Varsity contest were watching the play and question why I didn't call a technical foul, or at the least, basket interference. I advised player was trying to block shot, not just slap the backboard, therefore, no technical. One of the officials insisted you have to call a technical if it affects the outcome of the shot. I disagree. He then asks why I didn't call basket interference. Even though the backboard was shaking (slightly), my understanding is that you cannot have basket interference from just slapping the backboard.
