Having work a number of sub-varsity games, I've had my share of " WITHAYD???!!!" moments. Recently we had an IW on a punt and had to go back after the chains moved, on their on volition, and yes it caused the coach to get the red arse. So having the second clip is critical. My question wasn't presented like it should have been. The "first clip", the one seldom used, often ignored, and misunderstood - how has that clip "saved the day?"
