What must a coach refrain from doing when arguing a call to avoid immediate ejection?

A coach must avoid physical confrontation when arguing a call to prevent immediate ejection from the game. The rationale behind this is clear: physical confrontation can be perceived as aggressive and threatening behavior, which is intolerable in any sporting environment. Officials are trained to maintain a safe and controlled atmosphere during a game, and any action that compromises this can lead to severe consequences, including ejection.

While other methods of arguing a call, such as using a calm tone of voice or addressing the umpire respectfully, are important to the overall approach a coach should take, they do not hold the same critical weight as abstaining from physical confrontation. Remaining in the coach's box can also be a factor contributing to maintaining decorum, but it is the absence of aggressive physical actions that is most crucial in avoiding immediate ejection from the game.
