What is the primary purpose of the libero position in volleyball?

The primary purpose of the libero position in volleyball is to enhance defensive play. Liberos are specialized defensive players who wear a different color jersey to distinguish them from their teammates. Their role primarily focuses on improving the team's reception of serves and defensive responses to attacks from the opposing team.

Liberos are not allowed to serve or attack the ball above the net's height, which keeps their emphasis on defense and passing. This specialization allows for a strategic advantage; when the libero is on the court, they provide improved ball control and defensive stability, facilitating better set-ups for attacks from the front row players. By focusing on defensive skills, the libero plays a crucial role in the overall strategy and effectiveness of the team's defense and ball handling.
