This one can be described quite succinctly - penalties and penalty killing.
The Habs struck for FOUR power play goals. That's the difference in the game, right there in a nutshell. Take a penalty and the Canadiens were making the Penguins pay for it. The Pens, for their part, couldn't take advantage of their numerous power play opportunities in the first period and third period, especially when it would have made a difference in the game.
The encouraging thing is that other than the PK, the team looked quite strong, I thought. They played well at even strength and that bodes well for the future. They really need to get better on the PK, though, and stop taking so many penalties. I know they were being out skated by the Habs, and that led to some of the penalties, but they have to find some way to avoid the sin bin.
Next up: vs St Louis at the Igloo. This one is a SHOULD win game.
