With the 2014-15 season complete, NHL.com looks at some of the biggest storylines and award contenders.
It has been an unpredictable season for the top defensemen in the NHL.
Injuries have derailed the chase for the Norris Trophy for Mark Giordano of the Calgary Flames, Kris Letang of the Pittsburgh Penguins, Kevin Shattenkirk of the St. Louis Blues and Victor Hedman of the Tampa Bay Lightning. Zdeno Chara of the Boston Bruins finished second in the voting last season and while he too was injured, was probably not going to be part of the discussion anyway.
Nashville Predators defenseman Shea Weber was considered a favorite for the award shortly after Giordano was injured, but his team faded at the end of the season and several advanced statistics don't agree with that sentiment.
Before the season, Drew Doughty of the Los Angeles Kings was pegged as the favorite by NHL.com. Doughty has never won the trophy, but the argument that he was the best defenseman in the sport became a popular one while the Kings marched to their second Stanley Cup title in three years last spring.
Doughty has had a phenomenal year, especially considering the amount of ice time he had to shoulder while the Kings dealt with injuries to Jake Muzzin and Alec Martinez, and Slava Voynov being suspended for 76 games. He would be a fine choice for the 2015 Norris Trophy, but he is not the pick for NHL.com.
That would be Ottawa Senators talisman Erik Karlsson. Though Karlsson led all defensemen in points with 66 that is not the primary reason he deserves to win the Norris Trophy for the second time in his career.
