Which position is often specialized in defensive plays at the back of the court?

The libero position is specifically designed for defensive plays at the back of the court. This player has unique responsibilities and advantages that differentiate them from other positions. For instance, the libero wears a different color jersey and cannot attack the ball above the net's height, which helps maintain a clear focus on defensive gameplay. The primary role of the libero includes receiving serve and digging attacks from opponents, enabling more consistent ball handling and defensive coverage.

Moreover, the libero has the freedom to substitute in and out of the game without requiring a formal substitution process, allowing for strategic adjustments to enhance the team's defensive setup. Their specialized skills in passing, receiving serves, and playing defense make them essential for maintaining a strong backcourt presence, which is particularly important when the opposing team is serving or attacking.
