BOSTON — At first it seemed like the Bruins were going to gather some momentum coming out of the locker room.

In the first 10 minutes, they were outplaying and outhustling the Avalanche and had generated some good scoring chances. But after yet another lackluster power play, the Black and Gold lost momentum and the Avs had several chances of their own.

Nonetheless, despite being outshot 26-18 (13-9 in the period), goaltender Tuukka Rask has kept the game scoreless in his first start of the year. Here are a few other notes from the middle 20.

The second line of Brad Marchand, Rich Peverley and Patrice Bergeron was once again the best unit creating several of the Bruins’ scoring chances. Marchand nearly buried a 2-on-1 feed from Bergeron, but Avs goalie Semyon Varlamov was able to make a nice pad save for one of his 18 stops.

While Tyler Seguin is showing signs of a breakout season, Avs forward Matt Duchene is doing the same thing. The former No. 3 overall pick from the 2009 Draft has four shots and is creating several chances with his nifty playmaking.

Boston’s top line of Milan Lucic, David Krejci and Nathan Horton is struggling to generate anything in the first few games of the year. The trio has only two points combined in through the first 160 minutes of the season and have posted a plus/minus rating of minus-3.

What more can be said about the Bruins’ power(less) play that hasn’t been said already? After a short power play in the first period for seven seconds, the Bruins could only muster one shot on goal during their second opportunity with the man advantage. Even with the addition of Joe Corvo, it seems like the Bruins are still too passive with the puck.
