end of game, scoring a bucket for the other team

[Adam]

Frankly, I don't see how this is at all advantageous to the leading team. With a 4 point lead, have your PG hold the ball once it's passed in and just stand there. Worst case, he gets fouled, shoots free throws, and they still have a 4 point lead with 2 seconds left and a full court to travel.

Throwing the ball in the air would be more advantageous. Worst case, defense catches it and makes a three pointer; game over with a single point win.

No, if anything, the OP is taunting; and that's a pretty big stretch that would need to be determined by the officials on the court depending on other circumstances. If you go with taunting, you now have A down by 2, shooting two technical shots, then getting the ball at half court with 2 seconds left. Hmmmm.

Most likely, just blow it dead, do the directional announcement thing; and when coach asks what you're doing just tell him you thought the kids were confused so you made sure everyone had it right. What's he going to say? "My kids weren't confused."
