Im starting to question your ref knowledge and how you think it should go.
A coach may not know how to ref, but a coach knows what a foul is, what a double dribble is. to say a coach has no clue is simply ignorant....
Saying Coaches hardly know the rules is also ignorance. Maybe on the high school level, but if you don't think professional NBA coaches don't have a good grasp on the rules, then I don't know what to say....Lost my faith in your knowledge on this topic I suppose.
Is it possible that the games you ref are MUCH different than NBA games, but you are thinking they are the same?and the coaches are the same?
