This system combines the left wing lock and the torpedo. There are two offensive forwards the C and RW. The left wing plays like a left wing in the offensive end and a left D in the defensive zone and lines up on lw at the faceoff. The LW (who I call LD in this video) and RD stay on their side of the ice. The right D plays like a RW in the offensive zone and a RD in our end. The LD is really a middle D and is on the puck side in the offensive end and is the support player low in the defensive zone, always on the puck side. The RW and C cover the points in the D zone and force the puck on the attack. They can forecheck either in a 2-2-1 or a 1-3-1 formation. There are always 4 players on the attack.
