Off-side: skates decide, and the carrier must control the puck with the stick

Attackers may not enter the attacking zone ahead of the puck, and skate position alone decides it; the stick does not matter. A player is off-side once both skates are entirely past the leading edge of the blue line when the whole puck crosses that edge. A skate touching the line, or still inside the line's vertical plane, keeps the player onside. A puck carrier may go in ahead of the puck only if he already had it controlled on his stick before both skates were fully across the leading edge. If the puck deflects off an attacker outside the line, or off an official in the neutral zone, and goes back into the zone, apply off-side or delayed off-side as the situation calls for.
