Life is pretty good for the Bruins right now. Through two games on the new season three of the four forward lines have scored. The power play dormant for years is showing signs it might be a real weapon. A first-round draft pick given up as a bust in many observers’ minds appears to be coming around. The third line an Achilles’ heel the last two years is playing as well as any unit. Defensively they allowed just two goals in two games. And it doesn’t seem like they’re close to hitting on all cylinders. The Bruins received power-play goals from defensemen Zdeno Chara and Torey Krug and a couple of more even-strength ones from Brad Marchand and Jordan Caron to beat the Detroit Red Wings 4-1 at the Garden last night in the teams’ first meeting as Atlantic Division rivals. The Red Wings were on the second half of a back-to-back and playing the last of three games in four nights but the win still represented a quality two points for the B’s. “They controlled the whole game from the drop of the puck to the end of the game” said Detroit goalie Jimmy Howard who saw 37 shots and refused to give fatigue as an excuse. “They pretty much dominated in every aspect.” The Bruins didn’t allow the Red Wings to play their vaunted puck-possession game which can look like a game of keep-away when it’s going well. Tuukka Rask faced 26 shots allowing just one Henrik Zetterberg strike in the first period that tied the game briefly but the B’s goalie didn’t see a lot of testers. “We played such a good game as a team that I didn’t have to do a lot” Rask said. “No back-door plays or anything like that no odd-man rushing or anything just one shot and trying to take care of that rebound; our guys took care of it. So that’s why it was a really really good game for the second game of the season.” Chara played a big role on both power-play goals. Krug scored his first NHL regular-season goal with the 6-foot-9 Chara screening Howard from his new net-front position for a 1-0 lead in the first. Chara then took a feed from Krug and beat Howard on a nifty backhand shot that made it 4-1 and salted the game away in the third.
