My assistant coach is a source of ongoing advice to officials - travel, reach, 3 seconds, overtheback, comeonyougottacallthat in games, and I am always amazed when refs take it. I have tried to shut him up, but usually it takes a warning from the official or a simple question (who is the head coach here?) to close his mouth.
Anyhow, he always screams for over the back calls. This weekend when he yelled it out I was going to say that he should at least know that isn't the right call, ask for the push if you are going to ask for something. Before I can say anything, the ref who has blown the whistle yells for all to hear "Over the back!!" We skipped that lesson for the day
