PITTSBURGH — The Bruins offense has been the only one to show up offensively, and it led them to a 6-1 victory over the Penguins  in Game 2 of the Eastern Conference finals Monday. The B’s now hold a 2-0 series lead after taking both games in Pittsburgh.
Brad Marchand , who had just two goals in the Bruins’ first 13 playoff games, turned in a big night with two goals, which came in the first and final minutes of the first period.
Sidney Crosby  gave the puck away at the blue line on the first shift of the game, with Marchand racing his way to a breakaway and beating Tomas Vokoun with a wrist shot glove side. Goals from Nathan Horton  and David Krejci  in a two-minute span later in the period prompted Dan Bylsma to replace Vokoun with Marc-Andre Fleury .
Less than three minutes after the change, Brandon Sutter scored the Penguins’ first goal of the series with 34 seconds left in the first, but Patrice Bergeron ‘s line negated any optimism the Penguins could have brought into the intermission by turning some good neutral zone work into a rush that resuled in Marchand’s second of the night with nine seconds left in the period.
The teams skated to a scoreless second period before Bergeron took a feed from Jaromir Jagr in the offensive zone with plenty of open net and made it 5-1. Johnny Boychuk  poured salt on the wound with a slap shot goal from the point with just over a minute to play.
Interestingly enough, the last team to come back from an 0-2 deficit in the conference finals and win was the 1991 Penguins, who came back against the Bruins en route to winning the Stanley Cup . The series will head to Boston, with Game 3 being played Wednesday and Game 4 Friday.
WHAT WENT RIGHT FOR THE BRUINS
— The Penguins’ offensive stars have been duds through two games. Crosby had two bad turnovers, one of which led to a goal in the first minute of the game, and none of the Penguins’ top six forwards have managed a point through 120 minutes this series. Jarome Iginla got behind Zdeno Chara  to set himself up for a good opportunity on a rebound from an Evgeni Malkin shot in the first period off a rush, but he fanned on it. Bylsma switched James Neal and Pascal Dupuis late in the second period.
— Speaking of the Penguins not being so good, Kris Letang was on the ice for three of Boston’s four first-period goals. The Penguins have also gone 0-for-6 on the power play this series.
— A line other than the Krejci line scored, and that’s big. Krejci’s line produced all three goals in Game 1 (Krejci actually wasn’t on the ice for Horton’s goal, but Milan Lucic  was), but Bergeron’s line produced three goals in Game 2. This series was about offensive depth, and so far two lines have shown up with offensive output for the B’s while the Penguins have snoozed through the first two games.
— Normally it would look bad that the Bruins had just five shots on goal in the second period, but they weren’t the ones who had to come back from a three-goal deficit. That would be the Penguins, who got only seven pucks on Rask in the second period.
— Torey Krug busted out of his slump (by his standards, at least) as he followed going an entire 60 minutes without a point in Game 1 by picking up the assist on Horton’s first-period goal. Krug now has six points (four goals, two assists) in seven career playoff games.
WHAT WENT WRONG FOR THE BRUINS
— Marchand has two goals this series, but he also has two bad penalties. After going off for boarding Neal late in the second period in Game 1, Marchand was called for tripping (it may have been a slew foot) on Crosby in the second period Monday. It’s good to see something of an offensive outbreak for the Bruins’ leading scorer from the regular season, but he can’t get carried away with cheap stuff.
— The Merlot Line was on the ice for Sutter’s goal, but the trio turned in a strong performance as it got more consistent ice time. Claude Julien  didn’t play the trio of Gregory Campbell  between Shawn Thornton  and Daniel Paille  much in Game 1, but he had them out there more early on by giving them similar ice time to the third line in the first period. Aside from the goal against, they used the time well, keeping the puck in the offensive zone for a prolonged stretch midway through the first with Krug and Boychuk.
The line finished with an even rating, as it was on the ice for Boychuk’s goal, with Thornton and Campbell picking up assists.
