Brainwash players to stop at the net
This drill runs counter to everything I've been preaching in my career about passing the puck. But there's a good reason - hockey players should be using their teammates to get up the ice and into a position to score. Once you're there? Shoot the puck! Someone has to go to the net and stop and someone has to shoot the puck.
This small area game accomplishes both. Its other name: the tooth chipper. I've seen it happen, this one is intense.
