This is a defensive specialty position that is signified by one player who must wear a different-colored jersey from the rest of her team. The libero plays in the back row and often receives the attack or serve. This player usually leads the team in digs and is typically fast and able to change direction quickly. They often times have the first touch and have to turn that into a good pass to the setter. But they do have restrictions: A libero cannot block, set an attack from the front court, or attack the ball above the height of the net. They can also be subbed in and out of the game without counting against a team’s total substitutions. This rule is used strategically to sub a libero in for a front-row player when the front-row player is rotated to the back, where they might be less effective. And while a team can never have more than one libero on the court at a time, they do not need to field a libero at all times. Here's more on what the libero does.
