Which of the following is NOT a pregame duty of the referee?

The duty of ensuring that each team submits its roster and starters prior to the 10-minute mark is typically a responsibility that falls to the team and not specifically to the referee. While referees do engage in various pregame activities to ensure everything is in order, such as inspecting equipment, designating the official timepiece and timer, and notifying teams of the game start time, the formal collection of rosters and starters generally rests with the teams as part of the game administration process. This distinction highlights the collaborative responsibilities in preparing for a game, where the referees facilitate the environment but do not take on the specific administrative task of roster submission.

In contrast, inspecting and approving all equipment, designating the official timepiece, and notifying teams of the game start time are all fundamental aspects of a referee's pregame responsibilities, reinforcing their role in maintaining the integrity and flow of the game.
