Karlsson had 18 points (two goals, 16 assists) in 19 Stanley Cup Playoff games to help the Senators come within one win of the Cup Final, doing so playing with two hairline fractures in his left heel. The 27-year-old has at least 66 points, 16 goals, 45 assists and 27 power-play points in each of the past four seasons. He finished fifth in the NHL last season in total ice time (2,066:29) and fourth in ice time per game (26:50).

"The most dynamic defenseman in the National Hockey League is Erik Karlsson," said NHL Network analyst Ken Daneyko, who played defenseman in the NHL from 1982-2003. "It was on display all season long, especially in the playoffs. … Everything runs through Erik Karlsson on the back end, and that's why he's No. 1 on our list."

2. Brent Burns, San Jose Sharks

Burns led NHL defensemen with career highs in goals (29) and points (76). He was a finalist for the Norris Trophy for the second straight season and was named a First-Team All-Star, one season after he was voted Second-Team. Burns played 82 games for the third straight season and led the NHL in shots on goal (320) after finishing second in 2015-16.

"If he's got a step on you, forget it, it's over," Daneyko said. "He's too big (6-foot5-, 230 pounds) [and] he's too strong. Silky smooth hands, in tight for a defenseman, he buries it. There's a reason he led the National Hockey League in the backend in goals as well."

The 32-year-old averaged 24:51 per game last season and had six game-winning goals and 25 power-play points. He helped the Sharks advance to the Stanley Cup Final in 2016, scoring 24 points, tied for sixth-most by a defenseman in one playoff year.

No, he's not going to have 70, 80 points on a yearly basis, but just controlling the whole tempo of the game. So savvy, so smart, slick, terrific passer."

You talk about the gracefulness and the skating ability, you're not supposed to be that smooth at 6-foot-6."

The-26-year-old was second in the NHL with 33 power-play points last season and scored five game-winning goals.

He was voted one of the 100 Greatest NHL Players.

"I think he's the Energizer bunny," Daneyko said. "He's a guy that the motor's always going. We always talk about defensemen using their stick, well, yes, he can shoot [and] he joins the attack. He is on forwards before they know what to do with the puck, even highly skilled ones. So his timing of being able to close that gap and do all the little things that are so important to being a star defenseman in the League."

"For me, he's the closest to Erik Karlsson you're going to see in the National Hockey League," Daneyko said. "Not the biggest in stature (6-foot-, 201), but can do everything. … It's amazing the Penguins were able to win the Stanley Cup -- it shows the depth -- without a Kris Letang. How much better are they going to be with him in the lineup? Just hope for his sake and the Penguins' organization he can stay healthy. He's worth the price of admission. He's that good of a defenseman."

Cam Fowler took his game to another level this season."
