A game is in the balance between two teams, and the referee makes a call following an on-field incident. It is not understood or accepted equally by all who witness it. Emotions heighten from the players and coaching staff of both teams. However, as the one who made the decision, the referee is in control of what transpires.
While the decision itself is critical, conveying it is just as vital. The decision may not change yet when the referee engages the players, and there will likely be disagreement and insight into an alternate view, some engagement, and even possible acceptance. Not in the decision itself, instead of the appreciation for handling the situation. Players may walk away unhappy, but at very least one element has been taken care of. They were heard and felt it.
We encounter these situations daily. While there may be disagreement in opinion on the outcome of the decision, permitting others to engage in discussion, at minimum, provides them with a sense of worth and mutual respect.
While the decision is yours alone, you can walk away with it intact, and at minimum, the other party may gain a sense of respectful engagement. Although they may not comply, they can at least feel they had an opportunity to share their perspective and be heard.
Those referees who permit others to share their views are revered and respected well beyond the individual calls they make. It is not the decision that is remembered but instead their manner of delivery.
