In this drill, you have a 2 on 2 game with two nets on the goal line.
The coach will dump in two pucks, and teams must score on their assigned net. The goal is for the team to score both pucks, or just one, if the other team scores as well.
You can keep score for each line they are in and come up with a fun "punishment" for the losing team.
What I like so much about this drill is that it forces creativity and thinking since two pucks are in play, but it also forces the forwards to play defense and the defense to play forward, breaking players out of any boxes they may have.
You can also time limit each shift to stop players from trying to gain possession and waste time stick handling and defenders not pressuring in order to avoid forcing a play.
When you tell them they only have 30 seconds to score two goals, they get to work pretty quickly.
