Not long after I stopped playing volleyball competitively, the rules of the sport itself changed quite drastically. For sand doubles, the court was made smaller, and the scoring changed from sideout to rally scoring.
You still had to win by two, but you could win by someone else serving the ball into the net. Yes, winning often was predicated on someone else’s mistake, but this always had felt like a form of cheating, having grown up with that slightly safety net from which it was impossible to lose the game directly, at that very moment, by missing your serve.
The rule shift itself was something of a philosophical question.
Did the play begin at the service line, or when the ball crossed the midline threshold defined by the net?
