I know it would not be my job as an opposing coach to police the other teams pregame. But I think before I would stand there videoing the other team with my phone, I would probably walk over and let the other coach know that I intended to protest the game if he continued with the pregame wiffles. If the coach told me to go "F" myself or just ignored me, I would feel better about protesting if thats what I chose to do. I wouldtake some measures during the pregame to avoid having to protest and to make sure the game was settled on the field by the players.
