defense

There are three people in the back row during a volleyball match. The players in the position for back row passing are called defense specialists or just a DS. The job of the back row players is to pass the ball when the other team hits it over the net. They make the first contact and pass it to the setter (usually in the right front position). Each team is allowed one player that only plays back row. This player is called a libero, and they are always wearing a different jersey than the other players on a team. The libero does not rotate to the front row position and when they sub for another player to go front row it does not count towards the total number of substitutions each team gets. The other back row players must rotate to the front row or else make a substitution for a front row player. There are many different defenses a team can run including ones called perimeter and rotational defense. These defenses depend on where the hitter on the other team is hitting from and they defenses tell where the DS's should be standing.
