The Bruins are doing a lot of things right heading into the playoffs. They’re just not doing two critical things correctly — scoring and winning.

With a chance to capture the Northeast Division crown, the Bruins dropped a 4-2 decision to the Ottawa Senators last night, dropping them to the No. 4 seed and a first-round playoff series with the Toronto Maple Leafs, starting here on Wednesday.

The Senators, meanwhile, worked their way out of a matchup with the Eastern Conference favorite Pittsburgh Penguins. Ottawa will open instead with the division champion Montreal Canadiens.

“Turning the page” was the operative phrase in the Bruins dressing room. Though the B’s seemed to have regained most of their competitive edge that went missing for good stretches of March and April, they do not have the results to show for it. In their last nine regular-season games, they went 2-5-2. And in only one of those games did they score more than two goals. That came in a 3-0 win over the lowly Florida Panthers in which the third goal was an empty-netter.

If that trend continues, the B’s season won’t last much longer.

“Our biggest challenge going into the playoffs is scoring more goals,” said coach Claude Julien, whose team had a 36-22 shot advantage and missed the net 16 times last night. “If we can find that, it will make a big difference in our team because 5-on-5, for the most part, we’ve been much better lately. We’ve created a lot of scoring chances, but at the end of the day that’s the main thing that’s hurting us.”

David Krejci, one of the team’s premier offensive players, said the B’s can’t let frustration seep into their game — even though they’ve certainly been very frustrating to watch.
