What items can a coach possess while in the coach's box?

A coach is permitted to have a stopwatch, rules book, and scorebook while in the coach's box, as these items are considered essential tools for managing game strategy, player performance, and adherence to the rules. The stopwatch allows the coach to track game time, timeouts, and the pace of play, which can be crucial for making decisions on substitutions and strategies. The rules book serves as a reference for the coach to ensure compliance with the game rules and to clarify any questions that may arise during the game. The scorebook is used to keep accurate records of the game, including player statistics and scoring, which are important for evaluating performance and for future games.

Other items, such as coaching signs and markers, while useful for communication and strategy, do not have the same formal standing as the items listed. Personal belongings typically fall outside the accepted materials for the coach's box and could potentially create distractions. Therefore, the combination of a stopwatch, rules book, and scorebook represents the best practice and conforms to regulations for what a coach can appropriately utilize from within the coach's box.
