Backboard slap - BI?

[BillyMac]

A player cannot touch the ball, ring, or net while the ball is on the ring or within the basket. A player cannot touch the ball if it is in the imaginary cylinder above the ring. These are examples of basket interference. It is legal to touch the ring or the net if the ball is above the ring and not touching the ring, even if the ball is in the imaginary cylinder above the ring. It is legal to hang on the ring if a player is avoiding an injury to himself or herself or another player.

The backboard has nothing to do with goaltending. Goaltending is when a player touches the ball during a try, or tap, while it is in its downward flight, entirely above the basket ring level, outside the imaginary cylinder above the ring, and has the possibility of entering the basket. On most layups, the ball is going up immediately after it contacts the backboard. It is legal to pin the ball against the backboard if it still on the way up, and is not in the imaginary cylinder above the basket. Slapping the backboard is neither basket interference, nor is it goaltending, and points cannot be awarded. A player who strikes a backboard, during a tap, or a try, so forcefully that 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. When a player simply attempts to block a shot, and accidentally slaps the backboard, it is neither a violation, nor is it a technical foul.
