If a team regularly uses improper substitution procedures, is this an unnecessary delay?

Using improper substitution procedures creates confusion and disrupts the flow of the game, which is why it qualifies as an unnecessary delay. In volleyball, strict rules govern how substitutions must be conducted to ensure fair play and maintain the pace of the match. When teams do not follow these rules, it can lead to interruptions that delay the game's progress, causing frustration for both teams and spectators.

When teams are regularly found to be using improper substitution procedures, referees and officials are likely to penalize this behavior, recognizing that it contributes to unnecessary delays. This is crucial because volleyball relies heavily on the rhythm of play, and anything that interrupts that rhythm can be considered an unnecessary delay, regardless of whether or not a warning has been given. Hence, acknowledging that such behavior constitutes an unnecessary delay aligns with the principles of maintaining the integrity and flow of the game.
