Whast is the average volleyball experience for professional volleyball player to have?

Depends on how good you are obviously. But if you start off in a social team, you will get oppurtunities to play in higher divisions and end up going to trials for bigger and better teams. You might get selected by an academy team then they will take you to State team trials and maybe National team trials. With that you may make college teams or even go to the Olympics, but a couple of years atleast.
