i noticed first period friday, UND used a different attack into the zone on power play by passing the puck back to D at center ice and having the opposite winger curl behind to hit him in stride with speed into the zone. Blackhawks do this with Kane on the PP often. I think it works when the defense is laying back and stacking the blue line. It seemed Denver made an adjustment and started pressuring the puck carrier out of the zone so didn't see that breakout much after that. It was a nice wrinkle though and switched up the dump to start the power play.
