The Bruins did not exactly achieve aesthetic perfection last night. Far from it, actually. But for a team that had lost five of its previous seven games and seemed poised to find a new rock bottom through 50 minutes last night, they’ll take the two points and move on. The B’s scored two third-period goals to beat the Buffalo Sabres, 2-0, at First Niagara Center. The Bruins took a 1-0 lead at 12:54 of the third period on a strong shift from the David Krejci line. After some good puck control from Milan Lucic, Nathan Horton had two shots in tight, both of which Sabres goalie Ryan Miller stopped. But Krejci was there to tap home the next rebound. Then with 4:16 left in regulation, Krejci sent a beautiful backhand feed to Horton for a nice tap-in. Anton Khudobin made 26 saves for his first shutout of the season. The Bruins were coming off Saturday’s loss in Philadelphia, one of their worst showings of the year. “Right now, whatever should be simple is very hard,” coach Claude Julien said after yesterday’s morning’s skate. “You could even see it in our skate. It’s very complicated right now and guys are squeezing their sticks. We’re trying to do our best to give them some easy solutions and have them regain that confidence that we once had that makes us a better team. No doubt that’s our biggest challenge right now.” This core of this team has been together for a long time. The Bruins are used to making the playoffs and, barring a monumental collapse, they’ll make it again this year. Any chance the team is looking to simply get the regular season over and move on to what’s important? “I would hope not, and I don’t think so,” Julien said. “I’m explaining what I know is going on with our team, and yet from the outside, you guys have different views and see different things and you’re trying to find the reason for this. Right now we’re just in a slump, where every night there’s just one line going.” The B’s played a Sabres team that was without Thomas Vanek (hip) and, despite being only three points out of the playoff structure, has begun selling off players. On Saturday, Buffalo shipped defenseman Jordan Leopold to St. Louis.
