That's correct, assuming it wasn't done intentionally. Here is what the case book says:
'The purpose of this rule is to penalize intentional contact with the backboard while a shot try is involved or placing a hand on the backboard to gain an advantage. A player who strikes either backboard so forcefully it cannot be ignored because it is an attempt to draw attention to the player, or a means of venting frustration may be assessed a technical foul.'
If there is one rule that I really wish they would change this would be it. It seems like so many coaches think that's what the penalty should be anyway. This would help officials out a lot. They could count the basket and not have to hand out T's. This way we wouldn't get screamed at for being right.
It would be beneficial for both sides.
