Not much was working for the Bruins through the first two periods last night against the Canadiens. They had survived a potentially disastrous first period, thanks largely to Tuukka Rask. And though they played better in the second period, there was still nothing much doing offensively.

Down 1-0 heading into the third and having scored just one goal in their previous five periods, the B’s needed to change it up somehow. Coach Claude Julien did just that, switching right wingers on the top two lines, moving the previously snakebitten Tyler Seguin to the David Krejci-Milan Lucic line and putting Nathan Horton with Patrice Bergeron and Gregory Campbell.

The result? Two goals from the Krejci line — the equalizer from Seguin and winner from Krejci — on its first two shifts of the period and a 2-1 victory over the resurgent Habs at the Bell Centre.

“There are going to be some nights when we aren’t going as well and we all know that Krejci line’s been awesome for us,” said Julien, playing the game without regulars Brad Marchand, Daniel Paille and Shawn Thornton. “Tonight they didn’t seem able to create much and I said ‘Why don’t we move guys around here and give them a little spark.’ And it worked out.”

It was a strange game with a lot of odd bounces, most of which went the Bruins way, as the Habs had several chances that never amounted to a shot on net.

On one play in the second period, Tomas Plekanec had a clean breakaway but couldn’t settle the puck and wound up knocking it into the corner. In the first period, Dougie Hamilton saved a goal after Plekanec had faked an aggressive Rask and nearly put the puck into the opening on the shortside. But Hamilton scooted in behind Rask and thwarted Plekanec at the post. On another first period sequence, Colby Armstrong had the open backdoor, but Chris Bourque applied just enough of a backcheck to make him steer it wide.

But while he had some help, Rask was excellent in his own right, making 11 of his 20 saves in the first period, including a breakaway stop on Lars Eller.
