Inquiring Minds Want To Know ???

The hand is considered part of the ball when the hand is in contact with the ball. This includes holding, dribbling, passing, or even during a shot attempt. Striking a ball handler or a shooter on that player's hand that is incidental to an attempt to play the ball is not a foul.

No problem. Now, get ready for this. Here it comes. A1 is trying to control a rebound and has the ball cupped in one hand. From behind, B1 slaps the back of A1's hand that is in contact with the ball, causing A1's hand to push the ball in such a way that the ball goes out of bounds.

Easy part. No foul on B1. It's incidental contact, as defined above.

Hard part. Who caused the ball to go out of bounds, thus awarding the other team a throwin?

Since the hand is considered part of the ball when the hand is in contact with the ball, didn't B1 actually slap the ball, thus causing the ball, as part of the hand, to go out of bounds, thus awarding the throwin to Team A?

Or, did A1, being the last to actually touch the ball, cause it to go out of bounds, thus awarding the throw to Team B?

I've given you "a topic. Talk amongst yourselves."
