The thing that made it a back court violation in your opening post was that A2 gained possession in FC and with his next step went into BC.

If A2 had BC location by having all or part of feet already in BC, I would not have called a BC violation. The ball hitting the rim is a "try for goal" in my game. I am not going to try to read the player's mind as to what he/she intended. I will judge the play based on the facts. Ball leaves A1's hands, ball hits rim, therefore it is a try and team control ends. 4.12.2

Coaches, players and fans may argue that it was a pass. It might have, it might not have. I will give the "passer" the benefit of the doubt and call it a try.
