Erik Karlsson has heard the debate. In fact, he hasn't been able to avoid the noise. With the final ballots for trophy voting by members of the Professional Hockey Writers' Association due next week, should the high-scoring Senators defenceman win the Norris Trophy as the league's top blueliner? And if Karlsson had a ballot, who would get his vote? "If I couldn't vote for myself, I would probably vote for (Nashville's) Shea Weber," said Karlsson Wednesday. Until the winner is announced in Las Vegas at the NHL Awards Show in June, the debate will continue to rage over whether the 21-year-old Karlsson should carry home the hardware.
