It’s the perfect test at the perfect time.
The Bruins have rebounded from a 3-7-0 start and are the hottest team in the NHL . They have 13 of 14 and are unbeaten in regulation since Oct. 29 in Montreal.
The Penguins  are the top team in the East and have been the best team in the conference since the start of the season.
Now the top two teams in the conference meet in tonight in Pittsburgh.
“It’s going to be a great challenge for us,” said Chris Kelly , who scored the game-winner on Saturday night. “They are playing extremely well. They have their best player back and he seems like he hasn’t missed a beat. It will be an exciting game for us.”
Of course, the “best player” to whom Kelly refers is Sidney Crosby . He returned from his post-concussion symptoms on Nov. 21 with two goals in a 5-0 win over the Islanders. He hasn’t scored since but he does have 10 assists and the Pens are 5-1-1 in the seven games with him back in the lineup.
“It’s going to be a big game,” Bruins captain Zdeno Chara  said. “We haven’t faced them this season yet. Obviously they’ve got a healthy team now. I’m sure it’s going to be a good game.”
Tonight marks the first of four games between the last two Eastern Conference teams who have won the Stanley Cup . The Penguins won on Detroit’s home ice in Game 7 in 2009 while the Bruins accomplished the same feat back on June 15 in Vancouver.
Is this is a “measuring stick” game for the defending champion B’s?
“I think we’re approaching- we’ve got the right mind set going into every game right now,” new pugilist Joe Corvo said. “I feel like we’re playing the same way every game and we’re being super consistent and if we don’t at some point in the game, it gets corrected. I think it’s obviously a good test, they’re in first place so it’ll be an exciting game.”
With a regulation win, the Bruins will be just one point out of the top spot in the East, 15 games after being in the cellar.
“We want to get up there in the standings and this is a game for first place so it’s going to be a big one,” David Krejci  said.
There will be no rest after the game, either. The Bruins hop on a plane and go halfway across the continent for a Tuesday night game in Winnipeg.
