Which of these practices is recommended during the ball toss?

During the ball toss, it is essential for referees to have a clear and unobstructed signal to ensure that all players and coaches understand the start of the game or the resumption after a stoppage. Not holding a whistle in the mouth during the toss allows the referee to maintain focus and control over the action, as the whistle can potentially impede proper air flow, distract the referee, or prevent them from speaking or signaling clearly if needed.

In addition, having both hands free is advantageous for the toss itself, as it promotes a more even and accurate ball release, further reducing the chances of confusion among the players at the start of the jump ball situation. Other practices that may seem beneficial, such as using two hands in every situation or practicing extra movements, could complicate the process and detract from the primary focus of clarity and authority during the toss.
