NHL power rankings

1. Blackhawks    15-0 -3     —

We’re in the last week of February and Chicago still hasn’t lost in regulation. OK, there was that lockout thing, but, still, opening the season with 18 games without a regulation loss is remarkable (and record-setting) in any season.

2. Ducks    13-2 -1     +1

Jonas Hiller? Viktor Fasth? Doesn’t matter. Either seems to win in net — even when the Ducks fall behind, as they’ve done in the past six games.

3. Canucks    10-4 -4     +4

True, the 8-3 setback against the Red Wings on Sunday wasn’t pretty. Still, February hasn’t been too bad: Vancouver is 7-2-2 this month entering the week.

4. Penguins    13-6 -0     -2

The Pens endured minus Sidney Crosby as he returned from his head injury. Now it’s the team’s other star forward, Evgeni Malkin, who appears likely to be sidelined with a concussion.

5. Canadiens    12-4 -2     +1

The Habs remain one of the unexpected surprises this season, and they will continue their push with forward Max Pacioretty, who won’t face a suspension for boarding Rangers defenseman Ryan McDonagh.

6. Bruins    11-2 -2     -1

Boston entered the week on a three-game winning streak, even if only one of those teams (the Lightning) would make the playoffs had the season ended on Sunday.

7. Senators    11-6 -2     +7

Sens goalie Craig Anderson needed to be helped off the ice after a collision on Thursday. Ben Bishop is a solid No. 2, but Ottawa will need a healthy Anderson to contend.

8. Blues    10-6 -2     +1

St. Louis finally won a game at home in February. The Blues’ victory over the Blue Jackets on Sunday was their first this month at Scottrade Center, in their sixth attempt.

9. Devils    10-5 -4     -5

Among the top 11 teams, in terms of record, only the Devils have a negative goal differential. That will happen when you allow nine goals in two games.

10. Red Wings    9-7 -3     +6

The Wings are scoring, albeit mostly against Canucks goalie Roberto Luongo on Sunday (eight goals). They also scored four times on Predators goalie Pekka Rinne on Saturday.

11. Sharks    8-6 -3     —

San Jose could be set to get back on track on Tuesday as it plays a home game for the first time since Feb. 9, ending a woeful six-game trip that saw the Sharks drop all but one game.

12. Predators    8-6 -5     -2

The Preds enter the week having gone scoreless in back-to-back games. Even for Nashville, that’s a low goal output.

13. Maple Leafs    11-8 -0     —

The Leafs can be a little spotty on defense, and the team’s blue line is allowing a lot of shots. At 31.5, Toronto is 26th in the league in shots allowed.

14. Coyotes    8-7 -3     +1

Once the Coyotes learn to hold a lead, watch out. Phoenix held leads in two straight losses to end the week, including one with less than two minutes to go against Calgary on Sunday.

15. Stars    9-8 -1     +2

Dallas’ recent upswing includes a victory over San Jose on Saturday. The Stars will have to keep the momentum in the near future minus defensemen Trevor Daley and Aaron Rome, as both were placed on injured reserve.

16. Lightning    9-8 -1     +2

Tampa Bay needs to do more than just feast on the bottom feeders. Quality victories have been few and far between.

17. Hurricanes    9-7 -1     -5  

Congrats, Carolina. You technically lead the weakest division in hockey. Maybe the ‘Canes can make a statement against the Pens on Thursday.

18. Kings    8-6 -2     +7

A 3-0 run last week boosted L.A. back into playoff contention. Granted, those wins were against noncontenders, but still.

19. Rangers    8-7 -2     -11

The Rangers enter the week on a three-game skid. Worse, the talk of drastic changes on the horizon — even buying out underperforming forward Brad Richards — has heated up.

20. Flyers    9-10 -1     +2

If Philly wants to make a playoff push, it can’t lose to Florida, as it did Thursday.

21. Wild    8-7 -2     -2

Plenty of trade rumors abound, and it appears Minnesota could be ready to sell. Hardly the position Wild fans thought their team would be in after last summer’s splashy signings.

22. Flames    7-7 -3     -1

Jarome Iginla has been attached to trade rumors involving a few different teams. He’s still a member of the Flames, though, and he actually made people remember that with his first multi-goal game of the season Sunday.

23. Avalanche    7-8 -2     +4

The Avs have managed plenty of leads, but only the Caps have a lower winning percentage when leading after two periods, winning only 57.1 percent of the time.

24. Capitals    6-10 -1     —

Alex Ovechkin had his first hat trick in more than two years on Saturday. Two years!

25. Jets    8-9 -1     +3

Winnipeg is the second-worst home team in the league. Thankfully, the Jets are on a five-game trip and have won three of the first four.

26. Oilers    7-7 -3     —

Uglier than the Oilers’ record was that cheap shot forward Taylor Hall delivered to Wild forward Cal Clutterbuck on Thursday.

27. Islanders    8-10 -1     -4

Good news? Goalie Rick DiPietro cleared waivers and will be in the minors. Would be better news if another team picked him and the remainder of his 15-year deal up. Like that’d really happen.

28. Panthers    5-9 -4     +1

Winners of two of their last 10, the Panthers’ fade into insignificance is nearly complete.

29. Blue Jackets    5-12 -2     +1

A stat that illustrates Columbus’ woes: The Blue Jackets win a league-worst 16.7 percent of games when scoring first.

30. Sabres    6-12 -1     -10

Like it wasn’t obvious, but Buffalo’s problems extend far beyond longtime coach Lindy Ruff. The Sabres are 0-2 since his firing.
