The Penguins know that it will be a major test for them to contain Erik Karlsson. Karlsson has a goal and five assists in five games during the playoffs. "I don't think he changes your game plan," Craig Adams said. "It just makes things more difficult when he's out there. His biggest asset is his skating. He carries the puck up the ice, but you can't always count on him playing at the point. He's just so mobile. He's got that ability to jump into the play and the speed to get back."
