Drill is designed to reinforce the habit of playing pucks in the air with hands, not sticks.
Drill starts with a puck flip. Player plays puck with hand, and attacks quickly 1v1 to the net. After first puck is played, attacker works to get open for a second puck, that gets played quickly for a shot.
Encourage players to fight for space in tight spaces for second puck. Work to create quick space and opportunity in tight spaces. Try to discourage them from wandering around to find open space. Intention is to get them to look for quick chances under pressure, fight for space, and create opportunity in short windows.
