As a twice-fired coach in the NHL, Boston Bruins bench boss Claude Julien watches his colleagues come and go with interest. Yesterday it was former Stanley Cup-winning coach Peter Laviolette who got axed in Carolina — replaced by the guy he replaced, Paul Maurice.

Tonight’s opponent, the Tampa Bay Lightning, changed coaches from Barry Melrose to Rick Tocchet just a couple weeks ago, and they brought back former Bruins head man Mike Sullivan, who was an assistant under John Tortorella, to be associate coach for Tocchet.

What does Julien think about the game of “musical jobs”?

“It’s a double-edge sword, I guess,” Julien said yesterday after practice.  “You’ve got some good guys losing their jobs, and Peter Laviolette is one of those guys who’s done a great job everywhere he’s been. So you feel bad for him. At the same time, you’re seeing other people get an opportunity to get back in the game. I guess you can call it a vicious circle. And as an individual, you just hope that you stay on the right side of that circle and you keep working as long as you can. We all enjoy the job and, believe me, we do it because we love the game. There are a lot of challenges along the way, not just for you personally, but even for your family and what they’re put through. My heart goes out to those guys that have to make that adjustment and you’re always happy for guys that get another opportunity.”
