I found this drill a few years ago while watching a clip of the Detroit Red Wings Development Camp.
This is a terrific way to practice execution and scoring at full speed. The backchecker provides the constraint for the attacking players that forces a full speed attack that is realistic for a transition opportunity in a game. A common problem with many 2 v 1 drills is that the forwards can often take their time and slow down to an unrealistic pace.
From the defensive perspective the defenseman, goalie, and backchecker need to be on the same page as to how they defend this scenario and then effectively communicate to shut it down.
This drill is game-like. It is a recurring situation that is critical to take advantage of when on offense. The defending team has an opportunity to negate the scoring chance and then counter-attack in transition. Both teams can help build momentum for their side if they can execute.
This drill is also great for conditioning in a game situation. There are 6 players performing at 100% intensity followed by a short break. They are forced to compete through their fatigue as they perform the scoring scenario. Keep in mind your energy system goals for the practice – since this is a demanding drill you should consider how many repetitions you will do. We typically repeat 3 times from each side for each forward line. This way each player has the opportunity to backcheck once from each side. I’ve found that this ratio provides a good blend of conditioning while also allowing the execution to remain high. It is challenging.
