A Defensive Specialist is a player in sports, particularly in volleyball, who focuses primarily on defensive skills. Their main responsibilities include receiving serves, digging attacks, and ensuring that the ball does not touch the ground on their side of the court. They are often quick and agile, allowing them to react swiftly to opponents' plays. In volleyball, a Defensive Specialist typically does not play in the front row, which means they are not involved in blocking or attacking. Instead, they excel in skills like passing and libero techniques, contributing significantly to the team's overall defense and helping to set up offensive plays.
