Pass hits Rim
 

A1 is in the back court.
(a) Before he starts his dribble, Throws the ball to A2 and the ball hits the RIM and it bounces back to him.
(b) After he completes his dribble, Throws the ball to A2 and the ball hits the RIM and it bounces back to him.
Has A1 violated? Or what can he do next?

That makes it a dribble. Rule accordingly.

Does the ball contact the floor or return directly to the player from the ring?

I know of nothing that declares the rim the same as touching the floor. Backboard, sure, but not the rim. As such, throwing it off the rim seems the same as a player throwing it into the air and catching it. Then the question is whether the feet moved during such action. If so, travel or illegal dribble depending on which year's case play you want to use. If not, nothing has occurred.

Agreed. I read the term "bounces" as meaning the ball hit the floor.

If the ball returned directly to A1 (in which case I wouldn't use the term "bounces") the play is the same as A1 tossing the ball in the air and catching it. Rule accordingly, considering what else might have happened (pivot foot moving, etc.)

Oversight ...
 

Basketball Rules Fundamentals
19. A ball which touches the front face or edges of the backboard is treated
the same as touching the floor inbounds, except that when the ball touches
the thrower’s backboard, it does not constitute a part of a dribble.

Rim? An oversight by the NFHS?

Or intentionally and deviously done to drive us all nuts?

It's the NFHS, I think we all know the answer.

On the other hand we occasionally see a passed ball touching the basket net.

Most of us would probably just think, "Play on", not give it a second thought, and certainly never consider it to be a dribble.

So maybe the NFHS was right (I just almost vomited into my own mouth) in having the Rules Fundamental only specify the backboard?

Ah, I read the play differently....that the bounce was off the rim.
