Thinking the same thing! Volleyball is very structured, there are schemas and tactics basically for every event in the game. Additionally, at professional level the accuracy of the players is quite high so the variability should get lower e.g. the setter will set the ball very precisely and the spiker will attack from a specific position. What it might change is the timing (depending on how high the ball is), but usually the professional games are very fast so that should also simplify things.
