Zdeno Chara, Boston Bruins
A perennial all star, Zdeno Chara is renowned for having the fastest shot in the league.
At 6'9" (without skates), Chara is an incredibly imposing figure for opposing players. With 17 points, a plus-13 player rating, 99 shots on goal and 94 hits, Chara has again proved that he's one of the game's best defenders.
Drew Doughty, Los Angeles Kings
Averaging more than 26 and a half minutes per game, Drew Doughty is undoubtedly the defending Stanley Cup champion Los Angeles Kings' most important player on the back end.
With 20 points, plus-three player rating and 115 hits (a number that places him among the top-10 NHL defensemen in that department), Doughty has made the most of his minutes and has led his team to a 24-14-5 record, one that will almost certainly see it make the postseason again in 2013.
Duncan Keith, Chicago Blackhawks
Duncan Keith is, for all intents and purposes, the No. 6 defensemen on this list.
I'd almost say he is tied for fifth with the man in the next slide.
Keith has had another sensational season for the NHL's best team, the Chicago Blackhawks. Leading his team in ice time at nearly 24 minutes per game and being tied for second in plus-minus with a player rating of plus-18, Keith has shown that he is one of the league's elite blueliners.
With 23 points and 80 shots on goal, Keith has been no slouch on offense either.
