Brandon Sutter believes the Penguins began to play better defensively toward the end of their series win over Ottawa. The Penguins are well-known for their offensive play, but the team's defense, led by the underrated Sutter, is a crucial factor in their success."The last two games were our best two defensive games of the series," Sutter said. "That seems to be the difference for us. We score more goals when we play better defense. We know we can score goals. We have a lot of weapons, obviously. When we take care of our own end, it's kind of a special group." The Penguins will have their work cut out for them as they take on the Bruins in the Eastern Conference Finals.
