Pluses: It's hard to imagine them playing any better, but they just might with the addition of Brad Marchand, who returns Wednesday from a five-game suspension. I'd expect him to resume his role on the top line with David Pastrnak and Patrice Bergeron in what has been one of the NHL's best lines this season. The three are the top three scorers on the Bruins, with Marchand and Pastrnak (21 goals, 29 assists each) leading the way.
Next up is Tuukka Rask. His streak of 21 straight starts without losing in regulation is amazing. He's gone 19-0-2 with a save percentage of .941 and has to be in the Vezina Trophy conversation. He played Tuesday in a 3-2 road win against the Detroit Red Wings, but I wouldn't be surprised if he starts against the Rangers. Even if he doesn't, backup Anton Khudobin (10-3-4, 2.36 goals-against average, .924 save percentage) has filled in admirably, which is something Boston struggled with in the past few seasons when Rask didn't play.
Lastly, their ability to move the puck out of their defensive zone and into the neutral zone and offensive zone is second to none. They also have great balance between moving the puck from low to high and going east to west and diagonally on the ice. This makes it very difficult to match up and defend against them. The Bruins are able to keep teams off-balance by using the whole length of the ice. Along with the Lightning and Pittsburgh Penguins, the Bruins are one of the best puck-moving teams in the League.
