WILMINGTON, Mass. -- Boston Bruins coach Claude Julien likes consistency with his lines, but when the team isn't producing, changes will occur.

Julien tweaked his lines at practice this morning at Ristuccia Arena. Here are the sweater combinations:

Milan Lucic-David Krejci-Seth Griffith

Chris Kelly-Patrice Bergeron-Simon Gagne

Brad Marchand-Carl Soderberg-Loui Eriksson

Daniel Paille-Gregory Campbell-Reilly Smith/Matt Fraser

“Every team, every coach does that,” Julien said of the changes. “Obviously, there are some guys that aren’t quite playing at their level and they’re struggling to find their game. Some are just line combinations, so you make changes.”
