If a new rule is implemented but not uniformly understood, how will it be enforced?

The rationale for enforcing a newly implemented rule with discretion based on the game situation is grounded in the recognition that not all rules are immediately clear or universally understood by players, coaches, or officials. In this context, the umpire's discretion allows for a flexible approach to enforcement, which can help maintain the spirit of the game while addressing any confusion surrounding the rule's application.

Using discretion enables umpires to consider the specific circumstances of each game situation. This can include factors like the intent behind the rule, the nature of the infraction, or how such enforcement may impact the flow of the game. It emphasizes a balanced approach rather than a rigid application that could lead to misunderstandings or unwarranted penalties for players not fully aware of the new rule.

In contrast, the other options present less effective strategies for handling a rule that isn't uniformly understood. Enforcing a rule only when questioned by a team coach would create inconsistency and might lead to uneven enforcement. Enforcing it exactly as written without considering the understanding of those involved might result in unintended consequences or confusion. Informing players before the game is a proactive approach, yet it does not directly address the immediate application of the rule during the course of play, especially if misunderstandings arise during the game.
