As impressive as they looked in the opening round of the NHL playoffs, the Senators say they'll need to pack more punch to knock out the Devils in Round 2. "Our play is going to have to be even better than last series to be there," Senators defenceman Wade Redden said Monday, a day after the Devils eliminated the Lightning to set up a second-round Eastern Conference matchup versus Ottawa. "We've got to play real smart and real aggressive. All four lines are going to have to be going for us again."
