We have a new member in the NHL's upper echelon this week. Please welcome goaltender Scott Clemmensen (who?) and the New Jersey Devils. Keep an eye out for this week's big mover, the Dallas Stars. And say goodbye -- for now -- to this week's free-fallers, Pittsburgh and Edmonton. Here are the NHL power rankings from Dispatch reporter Aaron Portzline, with last week's rankings in ( ):

1. Boston (2) -- Still not buying the B's? Only once this season have they gone two games without a earning point.

2. San Jose (1) -- An eight-point lead over Detroit could easily shrink with 20 of the Sharks' final 34 games on the road.

3. New Jersey (4) -- Hottest club in the NHL with eight straight wins, six of them on the road. Jamie Langenbrunner is on fire.

4. Detroit (3) -- A five-game losing streak raises a question: Will (Os)good goaltending be enough this spring?

5. Washington (6) -- They'll meet New Jersey on Tuesday in a marquee matchup. The Devils won two of the first three in shootouts.

6. Calgary (5) -- The upgrade of Michael Cammalleri over Alex Tanguay has been huge. Cammalleri already has surpassed last season's numbers.

7. Chicago (9) -- The Hawks have suffered a winter thaw after the Winter Classic. They're 7-6-1 since New Year's Day.

8. N.Y. Rangers (10) -- Unsteady as she goes. After a walk-over in Atlanta on Tuesday, the Rangers' schedule stiffens.

9. Philadelphia (8) -- Too many nights off for this bunch. Witness a 4-1 loss in Tampa Bay and a 4-0 loss in St. Louis in recent weeks.

10. Montreal (7) -- With wunderkind Carey Price in net, the Habs have allowed 25 goals during a 1-5-0 slump.

11. Buffalo (11) -- Long, strange trip on both sides of the All-Star break. A loss in Tampa Bay (ugh) before the break, and a 10-2 win in Edmonton right after it.

12. Dallas (20) -- It's all good in Big D right now. The Stars have outscored opponents 17-6 during a four-game winning streak.

13. Florida (17) -- Some way, somehow, Toronto talk show host Doug MacLean is taking credit for the Panthers' resurgence, too.

14. Columbus (16) -- Fredrik Norrena played his way out of North America. Pascal Leclaire had ankle surgery. Steve Mason has mono. Is Wade Dubielewicz nervous yet?

15. Anaheim (15) -- The Ducks are 4-7-0 since Jan. 6. It's hard to fly when you don't know who your goaltender is.

16. Phoenix (13) -- Our predicted second-half collapse is under way. The 'Yotes are 0-3, outscored 11-3 since the break.

17. Carolina (18) -- The 'Canes have won four out of five after a five-game losing streak. But wins over Toronto, Tampa Bay and Atlanta don't mean much.

18. Minnesota (19) -- With Niklas Backstrom in goal, they've always got a chance. But that's a risky way of doing business.

19. Edmonton (12) -- A 10-2 home loss to Buffalo could go either way: a wake-up call or the point at which the Oilers' season went south.

20. Pittsburgh (14) -- Just when you think the Pens are back to their olds selves, they lose to Carolina (stink) and Toronto (disaster).

21. Los Angeles (23) -- Earned points in four of their past five; a five-game road trip to the East will be a stern test.

22. Nashville (25) -- The pipes have been turned over to Pekka Rinne, who has been very good some nights and very not-so-good on others.

23. Vancouver (21) -- Troubled times in the NHL's top city, where the Canucks have lost nine straight at home. Mats Sundin is not a savior.

24. St. Louis (24) -- Went into the break with wins in Boston and Chicago. A 4-0 win over Philly shows these guys are still playing hard.

25. Toronto (29) -- The Hockey gods don't want the Leafs to rebuild. Further proof is Tomas Kaberle's broken hand.

26. Colorado (22) -- A 1-7-0 plunge since Jan. 10 has left empty seats in Pepsi Center and almost-empty playoff hopes in the Mile High City.

27. Tampa Bay (26) -- Four of the next five games could ruin their lottery pick hopes: two against the Islanders and one each against Atlanta and Toronto.

28. Ottawa (27) -- Still want Jason Spezza, Blue Jackets fans? In a 1-0 loss in Columbus, the $8 million player was simply going through the motions.

29. Atlanta (28) -- Mysteries of the world: Stonehenge, the Ark of the Covenent and how Don Waddell is still the Thrashers' GM.

30. N.Y. Islanders (30) -- Right now, Jonathan Tavares is getting nervous: "Please, God, not Long Island or Atlanta!"
