The Behind the Net strategy is about cycling the puck around the net and setting up One-Timers. The basic starting setup for Behind the Net is a triangle formation with your forwards around the net. Carry the puck directly behind the net and this will trigger your other (2) forwards to setup in front of the net on the left and right sides. From here, you have the option of bringing the puck around the net from the left or right. When you do, this will trigger your other forwards to cycle around the net. You could cycle your forwards around the net all day if you wanted to (see video below) - but Ill show you some options to shoot in case you get bored.
1. One-Timer
Get your forwards setup in the triangle formation with the puck behind the net. Decide which side has less traffic and move the puck carrier around in front of the net. Your other forwards should cycle with you. Now you have another decision, if the passing lane is clear - pass it to other forward as he is moving across the net for a one-timer. If you time your pass right, your forward will be lined up with the opposite goal post for a great shot right inside the post while the goalie is out of position. If the passing lane is blocked, then you can cycle it back behind the net and try again, possibly cycling the other way.
2. Defensive Help
As youre cycling your forwards, sometimes your defense will rotate into the cycle. It depends on the position of your defensemen and which way you are cycling the puck. If you see your defensemen moving in, pass the puck to him for a one-timer. Aim low so that your forwards have a chance to pickup a rebound.
3. Point Shot
If the slot is packed with defenders, carry the puck to the outside boards and up to the point. Your defensemen should move to the center. Pass him the puck for either a one-timer in the high slot position, or if you have time wait there for a second until one of your forwards comes in front of the net for a screen.
