WILMINGTON, Mass. — Bruins head coach Claude Julien isn’t itchy to pull the trigger on line changes in the aftermath of his team’s recent 4-4-1 stretch of mediocrity.

Julien instead is emphasizing the need for all 18 skaters and both goaltenders to be better as Boston’s schedule continues to get tougher with a back-to-back this weekend against Pittsburgh and Washington. The Sidney Crosby-less, Jordan Staal-less Penguins visit the TD Garden Saturday afternoon.

“I think today, it’s not about changing the groups or changing lines or stuff like that. It’s mostly about bringing the tempo or work ethic up,” said the coach after his team’s 30-minute practice. “Anybody who watched our practice today, I think, saw that it had a pretty good pace. This is kind of what we’ve got to carry into our upcoming games here, bring our work ethic and commitment and everything else up to the next level that we have to bring it to.”

While the news hasn’t been great for the Bruins on the ice of late, it got a little better off the ice today. Julien said there was a possibility that concussed forward Nathan Horton, who is feeling better, might start to ride the bike and work out.
