BOSTON – No one on the Bruins or the Montreal Canadiens seems to have an answer for why the road team has won the first four games of the current Eastern Conference quarterfinal series between the clubs.

Game 5 is at TD Garden tonight, 7 p.m.

“I eat the same thing at home that I do on the road,” Bruins forward Shawn Thornton said. “So I don’t know what the difference is. I had a big streak last night and I’ll probably have another one Monday night [the night before Game 6]. It won’t matter.”

The success of road teams hasn’t been relegated to the Boston-Montreal series. In the 2011 Stanley Cup playoffs, road teams are 21-14. It seems that battling 82 games for home-ice advantage might be a waste of time.

“I think it’s just a matter of us, and I’ve told our team, let’s not worry so much about where we are but what we have to do as a team,” said Bruins head coach Claude Julien today when asked for the 1,000th time about why his team has fared better on the road than at home. “And I think that’s something that we are going to be focusing on.”

Regardless of the venue, Bruins defenseman Dennis Seidenberg said that he and his teammates know they haven’t played their best game yet. Although they prevailed in Game 3 and 4 in Montreal, they know they can be better.

“We want to carry over what we’ve done in Montreal. We still haven’t played the game we want to play. But there are signs of it,” he said. “And we definitely want to carry over some of it.”
