Not all heroes wear capes -- and most heroes barely get the recognition they deserve. There are plenty of stars shining in this league that don't get proper spotlight.

For this week's ESPN NHL Power Rankings -- voted on as always, by our panel of experts -- we identified an unsung hero on every team.

How we rank: The ESPN hockey editorial staff submits selections ranking teams 1-31, and those results are tabulated to the list featured here. Teams are rated through Tuesday night's games, taking into account overall record, recent success and other factors such as injuries. The previous ranking for each team is its spot in last week's edition.

1. New York Islanders

Previous ranking: 4

When we talk about the Islanders, we often credit their success to Barry Trotz's stingy defensive system. The coach deserves praise, but so do his two top blueliners Adam Pelech and Ryan Pulock (both just 25), who began this season right where they left off last: serving as the perfect pieces for Trotz.

2. Washington Capitals

Previous ranking: 1

Jakub Vrana has taken a strong step forward this season. The 23-year-old has 10 even-strength goals, trailing only Brad Marchand and Leon Draisaitl for the league lead. Vrana is on pace to smash his career high for goals (24) and points (47).

3. Boston Bruins

Previous ranking: 3

How about some love for Jaroslav Halak? Tuukka Rask has been excellent this season, in large part because of his managed workload. Halak has started eight games, going 4-1-3 with a .924 save percentage.

4. St. Louis Blues

Previous ranking: 2

Robert Thomas' statistics aren't there yet (three goals, two assists in 17 games) and the Blues' offense has been stagnant lately, but the 20-year-old is playing well. He leads the Blues in expected goals for percentage at even strength.

5. Colorado Avalanche

Previous ranking: 6

Both of the Avalanche goaltenders are back from injuries, which is welcome news. Though Philipp Grubauer is the unquestioned No. 1, Pavel Francouz has been a solid backup, going 4-2 with a .915 save percentage and 2.82 goals-against average.

6. Edmonton Oilers

Previous ranking: 5

Defense was a concern for the Oilers this season, and Edmonton was hoping prospect Ethan Bear would be NHL-ready. Bear has over-delivered, taking on a big workload (21-plus minutes per game).

7. Arizona Coyotes

Previous ranking: 7

Conor Garland is the most surprising player on the team this season, in a good way. Raise your hand if you would have guessed the unheralded Garland (once deemed too small for the NHL at 5-foot-8) would be leading the Coyotes in goals with 10.

8. Florida Panthers

Previous ranking: 9

When we talk about Panthers forwards, it's often do-it-all No. 1 centerman Aleksander Barkov. But Barkov's linemate, Jonathan Huberdeau, is on pace for a career year, with 28 points in his first 21 games.

9. Carolina Hurricanes

Previous ranking: 16

Perhaps a little under the radar, Martin Necas is putting together a solid rookie campaign. As the Canes battled through injuries to key forwards, the 21-year-old Necas consistently produced. He has 15 points in 21 games.

10. Montreal Canadiens

Previous ranking: 8

The Habs just got hit by the injury bug, and they'll be without Jonathan Drouin and Paul Byron for some time. Tomas Tatar (20 points in 22 games) earned his spot back on the top line because of his offense, and should stay, as long as he's defensively responsible and limits silly penalties.

11. Dallas Stars

Previous ranking: 23

Just like last season, the veteran Stars shouldered the blame for a poor start. And just like last season, when Dallas found its stride, a rookie has been part of the success. Keep an eye on 22-year-old Denis Gurianov, who is playing as if he belongs.

12. Winnipeg Jets

Previous ranking: 19

As Patrik Laine has evolved into a more complete (pass-first) forward, his good buddy Nikolaj Ehlers is lapping him in the goal-scoring department. Ehlers leads the Jets with 10 goals through 22 games (Laine has five, but an impressive 14 assists).

13. Pittsburgh Penguins

Previous ranking: 13

Plenty of Penguins have stepped up in the face of Pittsburgh's long list of injuries, but Jared McCann has perhaps been the most impressive. Since arriving last February, McCann ranks third on the Pens in points. Only Sidney Crosby and Jake Guentzel have scored more.

14. Vancouver Canucks

Previous ranking: 10

Elias Pettersson and Brock Boeser look fantastic, but so does J.T. Miller. Miller brings out the best in both young players, and has chipped in 20 points (including eight goals) to boot. When those three are on the ice, they dominate the shot attempt share.

15. Philadelphia Flyers

Previous ranking: 12

The Flyers' young defensemen are often in the spotlight (for reasons both good and bad) but veteran newcomer Matt Niskanen has been steady on the top pairing, and has helped Ivan Provorov get back on track.

16. Vegas Golden Knights

Previous ranking: 17

Despite tying for the team lead in goals (10), it still feels as if Reilly Smith isn't getting the credit he deserves. He's one of three Knights players with 20-plus takeaways, and has coughed up the puck only nine times.

17. San Jose Sharks

Previous ranking: 24

Tomas Hertl and Evander Kane have been San Jose's best forwards, but Barclay Goodrow has been underrated while playing a big role. Barclay is the most-used Sharks forward on the penalty kill, and is on pace to more than double his career highs of seven goals and 17 points.

18. Tampa Bay Lightning

Previous ranking: 18

After the Rangers bought out Kevin Shattenkirk this summer, the Lightning took a flier on the defenseman. It has paid off big time. Shattenkirk is fourth on the team in scoring while manning the top pairing with Victor Hedman.

19. Chicago Blackhawks

Previous ranking: 25

As a unit, the Blackhawks' blueliners absorb a lot of criticism, which means Duncan Keith usually doesn't get much praise. But there's nobody Chicago trusts more to gobble up minutes than Keith, who is looking solid in his age-36 season.

20. Calgary Flames

Previous ranking: 11

Calgary hasn't been able to build off last season's success, leading to frustration. One player who has matched the high bar set last season: Elias Lindholm. He's important on the penalty kill, mans the first power play, and should set a career high in goals for the second straight season after 27 in 2018-19.

21. Nashville Predators

Previous ranking: 14

Captain Roman Josi leads the team with 20 points. More underrated, but just as impressive (especially with offensive production) is Ryan Ellis. He has been on the ice for 28 goals at even strength, trailing only Leon Draisaitl for most in the league.

22. Buffalo Sabres

Previous ranking: 20

It's often the Jack Eichel show in Buffalo. This season, Eichel's top sidekick isn't Jeff Skinner, but rather Sam Reinhart, who has recorded a point in all but nine games this season.

23. Toronto Maple Leafs

Previous ranking: 15

While the offense isn't producing fireworks quite as we imagined, one player who is sparkling is rookie Ilya Mikheyev. He's relevant in the Calder Trophy conversation, with 12 points in 23 games.

24. Anaheim Ducks

Previous ranking: 21

While John Gibson (once again) stole the headlines early, it actually has been 39-year-old backup Ryan Miller who has been the Ducks' more reliable goaltender lately. Miller has yet to suffer a regulation loss.

25. Columbus Blue Jackets

Previous ranking: 26

Since his disastrous NHL debut in Pittsburgh, Elvis Merzlikins has been quite good (four starts, nine goals allowed, .919 save percentage). He's the unsung hero because he's giving the Blue Jackets a sliver of hope.

26. New York Rangers

Previous ranking: 22

It has been mostly about the kids in New York, but 26-year-old Ryan Strome is quietly having a very good season (on pace for his best as a pro) as he stepped up nicely for No. 1 center Mika Zibanejad, who has now been out for nearly a month.

27. Ottawa Senators

Previous ranking: 29

The Senators are exceeding our (very low) expectations. The penalty kill and Jean-Gabriel Pageau have both been terrific, but don't overlook Anders Nilsson. With Craig Anderson's contract expiring this summer, Nilsson is proving he could be the No. 1 goaltender moving forward.

28. Detroit Red Wings

Previous ranking: 27

We're not saying Robby Fabbri saved the Red Wings' season but since his arrival, Detroit has looked like a better team, going 3-1-2. Fabbri adds some talent to the second line while averaging more than a point per game as a Red Wing.

29. New Jersey Devils

Previous ranking: 28

The Devils traded for P.K. Subban because they felt they needed a true No. 1 defenseman. It hasn't worked out as well as planned, and neither has the season in general. The best blueliner for the Devils has actually been Sami Vatanen, with eight points thus far while skating 21:37 per game.

30. Minnesota Wild

Previous ranking: 30

There's not much going right for the Wild. One guy who is having a decent season is defenseman Brad Hunt. He's one of the few Minnesota players on the ice for more 5-on-5 goals for (15) than against (11).

31. Los Angeles Kings

Previous ranking: 31

The unsung hero is whoever decided to take down that Taylor Swift banner. At least it gave us a brief silly distraction from this bummer of a season.
