Erik Karlsson agreed with coach Paul MacLean's assessment that he isn't playing up to his past standards since returning from his Achilles injury. "I'm not playing the way I did when I got hurt and that's just the way it is," Karlsson said. "I'm trying to figure it out. Every once in a while it works and you feel pretty good out there. I've got to find the consistent game as well." Even a partially healthy Karlsson is valuable to the Senators though, as they continue to play in the postseason against Pittsburgh in the second round.
