Erik Karlsson is on the ice more than any other NHL player and is scoring unlike any defenseman in the past two decades.
The two-time Norris Trophy winner is on pace for 85 points, which would be the most since Brian Leetch of the New York Rangers in 1995-96. The electrifying star also is the key to the Ottawa Senators' push for the playoffs.
Karlsson is easy to keep an eye on because he plays almost 29 minutes a game. He's dominant on the power play, where he's put up 18 of his 52 points, good for fourth in the league.
If coach Dave Cameron continues to let his captain loose, Karlsson could surpass Leetch and challenge for another Norris Trophy.
