In Bounding the Ball

[grunewar]

Situation: Rec League B11-12 (they're short, which is important).

A1 is inbounding the ball on their own baseline after the ball went out of bounds off B. Ball is properly handed to A1 out of bounds at the lane extended. A1 is trying to lob the ball to A2 (who is taller than most 12 yr olds) right under A's basket (fan shape). Ball hits the netting and underside of the rim on A's basket directly after throw in before touching a player in bounds. Ref's whislte the ball dead and turn it over to B under A's basket.

Correct call?

Situation 9.2.2 A is as close as I can find to say it may be legal and play should have been let continue. But that situation discusses the backboard. Thoughts?
