WILMINGTON, Mass. — Let the tinkering begin.

Although things are always subject to change, Boston Bruins head coach Claude Julien flashed a new power-play look for his club today during practice. The Bruins are just 2-for-30 over the last seven games with the man-advantage. Injuries and overall ineffectiveness have both contributed to the struggles.

Included among the tweaks, a shift of Patrice Bergeron from the point on the first unit to  a forward’s slot along the wall with the second group.

Bergeron hasn’t played up front on the  power play since before the 2006-07 season.

“I’ve been playing there for a while. Now it’s back to being a forward, so I have to get used to it,” Bergeron said after the hour-long practice. “It’s no different than 5-on-5, except you have more space. But you still have to work hard.”

Bergeron also acknowledged the lessend defensive responsibility could help him out. Personally, he’s been mired in an awful offensive slump with no goals since Nov. 21 (19 games).

“It’s going to help. I’ll take them however. It doesn’t matter if it’s on the power play or 5-on-5,” said Bergeron.

The rest of the second unit today featured Dennis Wideman, Andrew Ference, Milan Lucic and David Krejci. On the first unit were holdovers  Marc Savard and Zdeno Chara with Aaron Ward, Phil Kessel and Stephane Yelle. Yelle hasn’t received any major power-play time this season, but Julien said the veteran center is one of the best Bruins players at battling in front and getting tip-ins.
