Patrice Bergeron has a power-play goal in this playoff series, and Brad Marchand has a couple of assists. But as a unit with Tyler Seguin, the line has not been able to produce anything on the scoreboard.

And if the Bruins are to put the Toronto Maple Leafs down, they need the trio that carried the team for much of the short 48-game season to get going offensively.

“We do. I’ll leave it at that, we do. They know we do. That has to come for us to be successful, starting next game,” said coach Claude Julien after last night’s 2-1 loss in Game 5. “It’s something that’s called accountability, and we have to have more of that from that line as far as being a difference maker or at least something positive. They’ve got to give us that.

“I thought the (Chris) Kelly line tonight was really good. (David) Krejci’s line has carried us, obviously the (Gregory) Campbell line has done their job. If we could get those guys going, it would really help our team a lot.”

They did have some chances. Though Marchand attempted just one shot that missed the mark, Bergeron and Seguin both had six shots on net. Bergeron had a great chance in the second period but couldn’t get the puck over James Reimer’s pad, who made perhaps the best save of the series on the play.

“I was turning around. The puck came out really fast at me. I was kind of still turning. I just tried to go as fast as I could,” said Bergeron. “Obviously I’d like to see that one again. It’s one of those things that in the moment you’re just trying to put it in the back of the net, but now obviously I had more time than I thought I had and it’s got to go in.”

Seguin also had a chance to lift it over Reimer in a second period power play — the Leafs later scored a shorthanded goal on that PP — and then hit the post with four seconds left.

The Bruins offense is simply too top-heavy right now with the Krejci line.

“Everyone else needs to step up and start contributing,” said Marchand. “We can’t rely on them every single game to get all of our goals. We got to dig down deep and have a much better game.”

While Bergeron had his chances and Seguin’s game was improved from his two duds in Games 3 and 4 in Toronto, this is the time of year for results.

“Well, we got to find a way. We can’t just be frustrated. We got to go out there and do it for our team,” said Bergeron.
