Concern about judgment

[Judtech]

It sounds like you did the right thing.
The only thing I would MAYBE point out is what would have happened if A made the shot to win the game? Would the player on the ground then been in danger of being injured by fans/players etc coming onto the court? I am not sure it is still enough of a reason to stop the action, but something to consider in the 'aftermath'. One would HOPE that Team A's bench was aware and would be Johnny On The Spot if that were to happen
