If I know the coach I will respond with, " I don't think they are setting illegal screens" or "I'm not keeping track of team fouls coach", in a calm, respectful manner, letting him know I am acknowledging him. Most of the time, the coach just wants to know he has your attention, and usually is o.k. after that for the rest of the game. If I don't know the coach, I will usually go over at a break and ask him what his concern is and that I will watch for that concern. These little things usually pay off big for me the rest of the game. Maybe coaching for quite a few years before becoming an official, gives me an insight to their mindset
