I really like this drill. It works individual defensive skills along with team defensive skills.
The idea is to get the puck out of the zone either by carrying it or passing to a teammate who can carry it. You don’t want the defensive team to just flip the puck out of the zone. The drill is designed to make the players work on transition from defense to offense in the defensive zone.
This drill along with the 4 Whistles drill from Rico Blasi really get the players working hard on transition.
