Slapping backboard

[BigDave]

Then why did your partner call a T?

It's a T if while a try or tap is in flight or is touching the backboard or is in the basket or in the cylinder above the basket, a player intentionally slaps or strikes the backboard or causes the ring to vibrate. [/B]

BktBallRef,

It's a "T" in that situation for unsportsmanlike conduct. Same as banging the ball off the wall/ceiling/fan after a play.
