How did the Bruins lose in the cup final last year? Yes, I know they were really banged up, but that's why they lost. The question is, how? What I saw happening was this: the Hawks threw pucks at the net, creating rebounds, and then beat the Bruins to the puck. It was that simple.
The regular season is a whole different game. In order to win in the playoffs, the Bruins are going to have to stop this from happening again. This is why the loss of Seidenberg and McQaid is such a big concern. They are two big guys who can clear the front of the net. Let's call clearing the front of the net "plan A.' Chara can't do it by himself. Without those two big guys, the Bruins are going to have to go with plan "B". Success is going to require strong back checking and Rask will need to limit his rebounds. That, and they will need to score a lot of goals, because they are going to be scored against.
Fortunately there is some reason for optimism. Remember that long winning streak the B's went on recently? It started with a game that was stolen by Rask. I think Rask is an excellent goaltender, but he has not stolen a lot of games in his NHL career. He's consistent and strong, but there aren't many times when you think, "this team should have lost, except for the amazing goaltending." In the game he stole, the puck kept ending up loose in front of the net, and the other team kept getting to it first. But Tuukka stood on his head and none of them went in. In the games that followed, this same thing happened again and again. After watching a few gazillion games you start to get a sixth sense about when a goal is going to be scored. Mine kept going off when there was a scramble in front of the net, yet time and time again the puck didn't go in. It seemed like some sort of magic. After a while it started to feel like the Bruins were invincible, and I think the guys on the ice felt that too. With a streak like this comes confidence, and with confidence comes strong, consistent, and resilient play.
The question now is, has the magic worn off? And if so, can Rask steal a game or two in the playoffs? Regardless, I think the Bruins fate lies out in front of their net.
