Las Vegas has been very good to Erik Karlsson. A day after picking up a seven-year, $45.5 million contract, the Ottawa Senators' superstar won the Norris Trophy to open the NHL Awards show in Vegas Wednesday night. Karlsson, 22, beat out Zdeno Chara of the Boston Bruins and Shea Weber of the Nashville Predators as the league's top defenseman. He finished the year leading all defensemen in scoring with a career-high 78 points, 25 more than the Winnipeg Jets' Dustin Byfuglien and the Florida Panthers' Brian Campbell. His point total was the most by a blueliner since Nicklas Lidstrom of the Detroit Red Wings hit 80 points in 2005-06. "One of the best days of my life," said Karlsson. "It's pretty hard to say how great it feels." Ending his season to remember, Karlsson will add another "best" day to his life as he'll be getting married in the next three weeks. Karlsson becomes the youngest winner since Denis Potvin took home the first of his three Norris Trophies in 1976.
