In this situation D1 is moving for the puck (or has the puck) and he has a step on the forechecker. D2 yells “WHEEL” to tell D1 to skate with the puck around the net. D2 should stay in position as a “pick” so that the forechecker can not easily cut across the top of the crease and check D1 on the other side. D1 should use the net as a screen by cutting close to net while skating behind it (not giving the forechecker room to check him, or get a step). D2 holds position in front of the net until D1 makes a pass, or skates the puck up ice. RW provides an option for a pass, C supports low giving D1 another option for a pass, LW moves across the ice.
The best time to use this breakout is when D1 has some speed, and the other team does not have pressure down low.
