I don't agree with the having to find something on the other end to please the coach that is upset with the call. No reason to change the way things are called just because the coach is upset.

However, I do agree with the patient whistle part. I don't think you go as far as judging whether A1's teamate would get the rebound, but if the shot is missed and the hold causes A1 a disadvantage in trying to rebound the ball you call it then. As justacoach was aluding to, don't worry about the coaches reaction, explain the situation and continue to call your game.
