Claude Julien  has changed his lines an uncharacteristic number of times this postseason, but his latest work is more drastic than perhaps any of the tinkering he’s done this season.
Out of the top six are Tyler Seguin  and Brad Marchand . Seguin skated with the third line in Friday’s practice, while Brad Marchand  was back to the Merlot Line with Gregory Campbell  and Shawn Thornton .
Marchand began last season on the fourth line before moving up to Patrice Bergeron ‘s line mid-season and never looking back. After finishing second on the Bruins with 28 goals in the regular season, he’s been among the many B’s who have opened the postseason with rather uninspired play.
Here are what the lines were in Friday’s practice, according to reports:
Milan Lucic  – David Krejci  – Brian Rolston 
Daniel Paille  – Patrice Bergeron  – Rich Peverley 
Benoit Pouliot – Chris Kelly  – Tyler Seguin /Jordan Caron
Brad Marchand – Gregory Campbell  – Shawn Thornton 
“Making line changes, that’s a part of trying to find solutions and it’s as simple as that,” Julien told reporters after Friday’s practice. “You’ve got to mix up guys who are not getting the results that we’d like to, so you’re trying to make changes that will maybe spark that part of our game.”
Here are some thoughts on the new lines for the Bruins:
– Not one line is the same as it was when the postseason began. The most radically changed trio is Bergeron’s, as Rich Peverley  played only parts of the last two games with Bergeron, while Daniel Paille  makes the jump from the fourth line.
– Julien obviously did this hoping that he can wake up some of his snoozing superstars. The top two lines in each game have gone scoreless thus far this series, as the team has had to rely on bottom-six forwards primarily for their scoring.
– While Seguin has been one of the Bruins’ worst players this postseason, taking him away from Bergeron is a risk. Seguin has underachieved in the past when playing on lower lines, but perhaps Chris Kelly  and Benoit Pouliot — two of Boston’s better forwards this series — can get him going.
– The Bruins are deep enough that they can be tied in a series through four games despite the fact that their best forwards have been kept off the score sheet, but the Bruins really need to get something out of David Krejci . If Krejci repeats his first-round performance from last postseason (one assist), the B’s could be in trouble. Remember, he was having difficulty generating points against Carey Price  in the first round a year ago. This is Braden Holtby, and the Bruins still haven’t consistently tested him for three periods.
– The Bruins should try to get Jordan Caron into the lineup, but for whom? As bad as Seguin was in the first three games before looking a little better on Thursday, scratching your regular-season leader in points should be out of the question. Caron brings a strong two-way game and had a stretch of eight points (four goals, four assists) in six games in March.
