Which of the following is NOT a recommended practice for referees during a game?

Narrowing the field of vision is not a recommended practice for referees during a game because it can significantly impair their ability to make accurate calls. Referees need to maintain a wide field of vision to monitor player movements, potential fouls, and the overall flow of the game. By keeping multiple angles open for visibility, referees can better assess the legality of plays and the actions of both offensive and defensive players.

When referees focus solely on a limited area or specific players, they may miss critical developments elsewhere on the court, leading to erroneous or inconsistent officiating. Thus, having an expanded perspective is crucial for making informed decisions and ensuring the integrity of the game. Understanding the conclusion of plays further adds to a referee's ability to evaluate actions within a broader context, enhancing overall game management.
