Rarely during his six-year tenure as coach of the Bruins has coach Claude Julien singled out one of his goaltenders for criticism, for one very good reason: In Tim Thomas and Tuukka Rask, the B’s boasted probably the best duo in the National Hockey League — guys who didn’t lose many games for their team, and won a great many.

So it was noteworthy Saturday when Julien assigned a share of blame on Rask after the B’s 3-2 loss to the Pittsburgh Penguins, saying, “You’re not going to point a finger, but your goaltender’s got to make some saves, too, at the right time.”

Rask was even more blunt in his self-criticism.

“Not too often I cost a game,” he said. “Today I did.”

So the scene was set yesterday for an interesting return to the nets by Rask against the Florida Panthers. It was a game in which backup Anton Khudobin might have been expected to play, but Julien wanted to come back with Rask.

The goalie did not disappoint, stopping all 28 Panthers shots in the Bruins’ much-needed 3-0 victory. It was Rask’s fourth shutout this season and No. 15 in his career.

“It’s just a fact that (bad games) happen sometimes,” Rask said. “You’ve got to shake it off and bounce back. I’m happy that I was able to do that. You know the schedule is crazy all the way to the end, so you can’t be feeling sorry for yourself after a bad game. You have to shake it off and go right back at it.”

The fact Rask did just that — and was given the opportunity — made Julien look not just like a good coach, but also a pretty good psychologist.

“I just thought after (Saturday), especially (with how) he stood tall and said, ‘I should have had a couple of goals,’ it was important for me to put him back in,” said Julien. “Say, ‘Here’s an opportunity to go out and battle back, and the quicker the better.’ He responded well.
