It certainly looks like the Montreal Canadiens are starting to become a “thing” for Bruins goaltender Tuukka Rask. Rask was pulled after giving up his third goal on the 18th shot he faced in the second period of Thursday night’s 4-1 loss to the Habs at TD Garden, and dropped to a 2-10-2 career record versus the Bleu, Blanc and Rouge in his NHL career. The other numbers aren’t much better with a save percentage under .900, and a goals-against average that’s climbing toward 3.00. It was also the fourth time Rask has been removed from a game this season, with each of those games taking place over the past six weeks. “I don’t know, I mean I haven’t played too many bad games against them, just can’t get the wins,” said Rask. “I mean it sucks, but what can you do. Just hopefully by the end of my career, they [the stats] are better.” When you look at the balance of the stats against Montreal, however, Rask hasn’t exactly played a lot of good games against the Habs either. Rask wasn’t 100 percent at fault for the three Montreal scores. It appeared he was screened on the Alexei Emelin shot that opened up Montreal’s scoring, and Max Pacioretty scored on a 2-on-1 breakaway created when Johnny Boychuk and Torey Krug didn’t get back on defense quickly enough. But the second-period power-play goal allowed to Brian Gionta wasn’t a great one that trickled through on a tipped puck, and was the final straw for the Bruins coaching staff. Claude Julien wouldn’t get into the exact reasoning behind the goaltending switch in the second period, and scoffed at follow-up questions about the decision.
