A referee blows his/her whistle to stop the action. No referee does this lightly as all the attention in the arena is suddenly focused on him/her. But you disagree with the call and make your disapproval known, loudly and occasionally inappropriately. The referee made the call based on the rules, player action and his/her experience and your comments aren’t likely to reverse the call. More importantly, at that moment, your player(s) need your attention. They may have just committed a foul, turnover or made some other mistake that may seriously impact the game. Save your breath – for your player(s). Coach them through this moment which, especially for younger players, is a teaching opportunity.
