L is the Libero.
Yes, the libero can serve in volleyball. However, they can only serve for one position. Once the libero serves in a particular position in a game that is the only position where the libero is allowed to serve. However, the libero is not required to serve in that position for all subsequent rotations.
There is not always a libero. It is the coaches decision to have or not to have a libero, just like it is his or her choice to field any other position on the team.
A libero is a player that specializes in passing the ball. This position is for those who are very good at passing and defensive strategy
The Libero in Volleyball is like a GoalKeeper in Soccer, The Libero is the most skilled defender in Volleyball. And in the rules of volleyball the Libero must wear a contrasting outfit to the team
Yea, everyone is important on a volleyball team, but I personally think that the libero is the most important. Mostly because the libero can pretty much do anything. and can go in for any position
No you do not need a libero in volleyball. During the 2012 club volleyball season teams will be allowed to have up to two liberos.
