What does maintaining an open angle allow referees to do?

Maintaining an open angle allows referees to monitor the play without obstruction. This positioning is crucial for making accurate decisions, as it provides referees with a clear, unobstructed view of the players and the ball. From this vantage point, referees can better assess fouls, violations, and other critical aspects of the game without interference.

Being in an open angle enhances a referee's ability to perceive the flow of the game and understand the dynamics between players, which is essential for making informed and fair calls. Effective positioning also contributes to the overall authority and credibility of the officiating, as players are more likely to respect calls made by a referee who can visibly see the action unfold.

In contrast, observing players only from the sidelines limits the referee's perspective on the game, while distracting players can negatively impact their performance and create a hostile environment. Remaining uninvolved would compromise a referee's role and effectiveness, as their job is to actively oversee the game, ensure fair play, and enforce the rules.
