Olivier Bouchard was nice enough to record last night's scoring chances. Here's the 14-game history of the Habs 2009-10 playoff run:
Here's the time played by score for the series:
The Habs were down 35.5% of the time, and up 37.5% of the time. Score effects had very little impact on total scoring chances - Pittsburgh really did get almost twice as many opportunities as Montreal, a very effective defensive strategy by the Canadiens if there ever was one.
