This is not a game chaging play by the D but what it does is buy time and relieve pressure. I call this the "BLUE LINE RULE"

The puck gets spotted out of the OZ and you must go back and get it.  You are under pressure and really don't have a play.  All you are looking to do is bank the puck off the wall and get it over your blue line.  This will trap the player chasing the puck in the zone and often creates an off side play (like in the clip).

One reason this works so well is becasue the Forward chasing the puck rarely stops to get back on side.  The will loop once the puck goes past them and give the D time to get up and establish a good gap again. 

Educate your D on little plays like this to make their game easier and more effective.  All they have to do is feel pressure and get the puck back over the blue line as opposed to bringing it back in their own zone. 

Add this to your next practice in your NZ play.
