Less than 15 minutes into the game, the Montreal Canadiens realized they weren’t playing the Washington Capitals anymore. Oh, not even close. Everything that worked so perfectly against the Capitals was failing miserably against the Pittsburgh Penguins, who might exploit a weakness better than any team in hockey Defensemen Kris Letang and Alex Goligoski each had a goal and an assist, and the Penguins shredded the Montreal penalty-killing unit that Washington never solved in the opening round. Pittsburgh beat the Canadiens 6-3 Friday night in the first game of the Eastern Conference semifinals. Sidney Crosby set up two goals, and Jordan Staal and Sergei Gonchar also scored as the Penguins’ improved power play went 4 for 4. By contrast, the Canadiens killed 32 of 33 Capitals power plays in the first round. http://sports.yahoo.com/nhl/recap;_ylt=Ap7xjzHPKnLcE15r0O3SMUt7vLYF?gid=2010043016
