Senators general manager Bryan Murray wants the team to free up some space for Erik Karlsson, Ottawa's Norris Trophy candidate and offensive trigger who was held off the scoresheet and targeted physically by the New York Rangers in Game 1 of the opening playoff series. "He has got to get to the puck first and move it quickly," Murray said. If the Senators can spend more time in the Rangers' zone, they are going to try to get more shots through to goaltender Henrik Lundqvist. The Rangers love to block shots, ranking among the league leaders in the department, so look for the Senators to try to delay occasionally and sneak a pass across ice at the last second. Karlsson did not practice Friday, probably to avoid a bunch of questions as much as anything. If the Senators are going to get back in this series, they need No. 65 to make the kind of impact he had all season. Goalie Craig Anderson would like to see Ottawa's defensemen and forwards try to slow up the Rangers' forecheckers "and keep them from making big hits" on Karlsson. "It may take him a few shifts to get his rhythm," Anderson said, "but he's our best player. When he's going, things go well for us."
