When refereeing on ball, should the referee focus on the illegality of the defensive player?

Focusing on the illegality of the defensive player while refereeing on ball is critical to ensure a fair and regulated game. When the ball is in play and a defender is closely guarding an offensive player, the referee's primary responsibility is to observe any potential fouls or breaches of the rules committed by the defender. This includes actions such as holding, pushing, or illegal use of hands, which could impede the offensive player's ability to move freely and execute plays.

By concentrating on the defensive player's actions, the referee can effectively identify and penalize illegal plays, thus maintaining the integrity of the game. This vigilance helps to uphold the rules of basketball and protect the players, ensuring that the game unfolds within established guidelines. Moreover, addressing defensive illegalities promptly can help prevent escalation of physical play and maintain control of the match.
