Are teams allowed to select different numbers of Liberos for every set?

In volleyball, the rules stipulate that teams must maintain the same number of Liberos throughout a match. Each team can have a maximum of two Liberos, but once the number is set at the beginning of the match, it cannot be altered between sets. This consistency is vital for maintaining fairness and ensuring that coaches and players can develop strategies based on the roles of the Liberos. Having a fixed number ensures that all teams are on equal footing regarding positional changes and substitutions.

While there could be varying reference points or interpretations around the flexibility of roster management, the fundamental rule remains that teams must adhere to the initial selection of Liberos for the entire duration of the match. This approach fosters a structured environment in competitive play.
