SETUP
Start with 2 defenseman at the top of the circles. The rest of the defenseman are along the boards at center ice.
Forwards are on all 4 blue lines with pucks.
On the first whistle, the far forwards exchange lanes (and can exchange a puck) before they attack. They must attack from outside of the neutral zone face off dots.
The defenders jump up the to neutral zone and attempt to gap up properly and handle the excess speed.
The 2 v 2 plays out until the coach blows a second whistle.
On the second whistle, the first set of forwards is done, the second set of forwards on the near blue line start and race around the far face-off dots before they begin their attack on the defenders.
The defenders that just finished the original 2 v 2 race to gap up against the second set of forwards.
