Why is understanding the opponent's movements important in defense?

Understanding the opponent's movements is crucial in defense because it allows a defender to anticipate plays and improve their defensive positioning. By closely observing how the opponent moves on the court, a defender can predict potential passes, shots, or cuts towards the goal, enabling them to position themselves more effectively to intercept the ball or block their opponent's path. This proactive approach not only disrupts the attacking flow of the opposing team but also creates opportunities to regain possession. Additionally, being aware of an opponent's tendencies can help a defender react more efficiently, which is vital in a fast-paced game like netball where split-second decisions can make a significant difference in the outcome of a play.
