Which of the following is NOT a responsibility of a non-active referee during the toss?

During the coin toss at the start of a basketball game, the responsibilities of a non-active referee are primarily focused on ensuring the procedure runs smoothly and correctly. One of the key roles is to ensure that the game clock is ready, the alternating possession arrow is correctly set, and to call back any toss that may be deemed poor or improper.

Calling fouls against jumpers, however, falls outside the responsibilities of a non-active referee during the toss. This task is typically handled by the active referee, who is directly involved in the jump ball itself. In this context, the non-active referee should remain focused on supporting the flow of the game by monitoring the overall process of the toss rather than intervening in the actions of the jumpers on the court. This distinction clarifies why the correct answer is that calling fouls against jumpers is not the responsibility of a non-active referee.
