[bigwhistle]

Was the Team B player trying to block the shot and just happened to slap the board with his follow through? If so, you probably should have sucked on your whistle and let play continue. However, if the player was showboating or just trying to hit the board hard enough to make it vibrate, a T would definitely be justified.

More times than not, this play is the result of an unsuccessful defensive swat by B and should be left alone.
