Lebron recently did it although NBA rules obviously applied. I recall doing it in HS myself a million years ago.
By digging deep into the grammar/wording of various sources, I do indeed see BM's point. I also understand the points made by others.
9.5 SITUATION: A1 dribbles and comes to a stop after which he/she throws the ball against: (b) the opponent’s backboard;RULING: In (b), A1 has violated; throwing the ball against an opponent’s backboard or an official constitutes another dribble, provided A1 is first to touch the ball after it strikes the official or the board. (4-4-5; 4-15-1, 2; Fundamental 19)
4-15-1: A dribble is ball movement caused by a player in control who bats (intentionally strikes the ball with the hand(s)) or pushes the ball to the floor one or several times. It is not a part of a dribble when the ball touches a player’s own backboard.
Interesting that the case indicates that throwing the ball against the opponent's backboard is a dribble but yet that action does not fit the definition of a dribble.
Indeed, there are loopholes in the rule/case books and often times they lead to weird/lengthy, and borderline irrelevant, debates.

Makes it fun though doesn't it?
