Volleyball - Net play
Net touches, center line, and overreach sorted out.
Volleyball does not punish every visible brush with the net or every foot that comes close to the line. The real question is whether the player entered protected space illegally, contacted the net during the action of playing the ball, or interfered with the opponent's ability to play.
Quick ruling: identify which protected space was affected first. Ask whether the player touched the net while playing the ball, crossed under in a way that interfered, or reached beyond the plane before the opponent's play allowed it.
