When the 1st line isn't elite, the Bruins struggle. And it has not been elite this season. They are only +3 5v5 this season. For reference the Krejci line is also +3. Break them up, move Bjork up, he deserves a chance. Would also consider calling up Cehlarik and Kovar, they have played reasonably well together in Providence. And I don't care how much Backes is paid, he needs to sit. He and Acciari are the worst forwards on the team right now.
