San Jose Sharks defense is the best in the NHL, sorry Nashville. A team mustered with talent, mostly on the backend. Features Brent Burns, one of the best offensive defenseman in the league, Erik Karlsson, the other best offensive defenseman in the league, and Marc-Edouard Vlasic, one of the best defensive defenseman in the league. San Jose managed to make a move on the biggest defenseman in the league, bringing in Karlsson is an instant upgrade to an already good team.
Here is a stat for you, since 2011-12 Karlsson has 447 points, and Burns has 383. The next best defenseman in that span has 337. San Jose believes they have 3 Norris Trophy Canadians on their one team. Can they convert the 3 Norris Trophies into won Stanley Cup? Time will tell.
