In response to JWensink's comment:
Before the game in an interview Kunitz was describing how the B's move the puck out of the zone. D to D behind the net and up the boards. It was obvious that the Pens decided the way to beat this team was to attack 5 on 5. It was a full blown assault like Ive never seen before. The Pens were going to the spots they knew the puck was going to be, and they were all in with everybody. It was as if the B's were killing a PP all night. They were outplayed and out competed and outcoached. Now, nobody hates that team more than me- but they get all the credit. No excuses. They kicked azz all night. It was the most aggressive attack I can remember, it was actually incredibly impressive.The B's need to figure out how to make this ballz out forecheck pay the price for going all out in deep. Adjustments will have to be made.
this. plus they have a bunch of skilled, tough guys who play (or were playing for one night) with no fear. of course being down by 2 goals makes that easier but still.
