Throw-in: Did I miss something?

[The R]

OP. A1 is OOB following a made basket with full court pressure from team B. A1 attempts a long throw from under the backboard that clips the bottom side(not the back) of the backboard padding. The ball then ricochets inbounds.

From New Lead my partner signals a violation and declares team B ball.

During the next timeout he informs me that during a throw-in the only legal part of the backboard the ball may strike is the front. I told him I would have to look that one up as I had never heard of that rule.

So here is the fruit of my research. This case play does not specifically reference the "bottom" of the backboard however it does say face and sides.

Case book Page 72 9.2.2
Throw-in violations
Thrower A1: (c) throws the ball against the side or the front face of the backboard, after which it rebounds into the hands of A2.
Ruling: The throw-in in (c) is legal. The side and front face of the backboard are inbounds and, in this specific situation, are treated the same as the floor inbounds.


Am I understand that he was wrong?
