We are now through the second month of the season (and for many teams, one quarter of the way through the season), and there is plenty of movement in the power rankings; some teams jumping because of hot streaks, others falling far down the line because of losing streaks. Lots of reasons for both: injuries, hot or slumping goalies, hot or slumping offenses, poor special teams. Detroit is the new top team, while Colorado, Chicago, Columbus and Dallas are new faces in the top-10. As will always be the case, the power rankings are based on the OCPR, which is derived from the following stats: Wins-Losses-OT Losses; Point percentage ? which is the percentage of available points the team has secured during their games played; Goals for and against; Shots for and against; Power play and penalty killing %; Percentage of wins in 1 goal games; Percentage of wins in overtime games; Point percentage over the last 10 games; Season point percentage of opponents faced over the last 10 games; Team faceoff percentage (FO%), and 5-on-5 goal ratio. Biggest jump: Phoenix +9. Biggest drop: St. Louis -16 All stats and information as of November 30, 2010; last month?s rankings in brackets 1. Detroit Red Wings ? 75.518 (3) Leading the league in point percentage (77.3%), goals per game and second in 5-on-5 goal differential. They don?t have as many points as a couple of Eastern Conference teams, but they have also played the fewest games in the league. 2. Philadelphia Flyers ? 73.405 (9) Tops in the league in 5-on-5 goal differential. Great offense and defense but could be higher if they weren?t 1-4 in overtime games or did better in one-goal games (42.9%) 3. Washington Capitals ? 68.876 (4) Their power play is third in the league, and their point percentage (72%) is second to Detroit. Went to overtime eight times already, but are 6-2 in those games. 4. Pittsburgh Penguins ? 65.951 (8) Pens are on a tear right now, earning 95% of the possible points in their last ten games. All this and their power play is still only at 16.2% and they still don?t have Jordan Staal back. 5. Colorado Avalanche ? 63.227 (13) The young Avs are doing their part to dispel the notion that they will take a step back this year: 2nd in the league with 3.46 goals per game, and are outscoring their opponents 59-43 during 5-on-5 play. 6. Montreal Canadiens ? 59.640 (10) If they want to sustain their success, they need to give Carey Price some help. They give up almost the same number of shots they take (30.9), but lead the league with 1.96 goals against. 7. Chicago Blackhawks ? 59.140 (12) Their defense hasn?t been as consistent as last year, but their offense and power play are humming along nicely. A concern: They are winning less than half of their 1-goal games. 8. Columbus Blue Jackets ? 57.387 (15) Many pundits have them pegged as this year?s version of the Coyotes of a year ago, but a recent home-and-home sweep at the hands of Detroit may quiet the talk. Great penalty kill (85.2%) but horrendous power play (11%), and a perfect 3-0 in extra time. 9. Dallas Stars ? 55.997 (17) A roller coaster season in Dallas so far filled with hot and cold streaks. Below par special teams, giving up more shots than they take, but they have won 72.7% of their 1-goal games and are keeping the puck out of the net. 10. San Jose Sharks ? 53.058 (6) They are playing far better than their record indicates, as subpar goaltending has done them in so far. Their special teams are good both ends, and they lead the league in shots per game (34.8) while only giving up 28.3. 11. Los Angeles Kings ? 52.354 (5) After a torrid start the Kings have come back to earth. They are having a lot of trouble scoring (2.61 per game), but their goaltending and penalty kill (85.9%) have been awesome. 3-0 in overtimes. 12. Vancouver Canucks ? 52.296 (14) Dynamite special teams play (25.3% PP, 86.9% PK) would stand out more if not for the 31.1 shots against per game their ?revamped? defense is allowing. Only 1-3 after regulation, too. 13. Tampa Bay Lightning ? 51.952 (2) Their 14-8-3 record hides the fact that they have given up more goals than they have scored. Goaltending continues to be the issue, as they don?t allow too many shots. Their penalty kill is one of the best in the league (87%). 14. Boston Bruins ? 51.516 (7) Tim Thomas can only do so much, and he clearly can?t help the power play (15.8%) improve. They are second in the league allowing only 2.0 goals against per game, even though they give up a whopping 33 shots against. 15. New York Rangers ? 50.437 (20) Can someone please give Lundqvist some help? They allow 3 more shots against per game than they take. Their team faceoff percentage is second-worst in the league (44.7%), but they win 70% of their 1-goal games. 16. Atlanta Thrashers ? 50.251 (24) Ended November on a five game win streak, due in large part to Dustin Byfuglien and Ondrej Pavelec. They need to play better defensively though, as they are giving up a league-high 35 shots per game. 17. St. Louis Blues ? 49.716 (1) Last month?s #1 team is in a free fall thanks to being riddled with injuries. Halak has come back down to earth, but the real struggles are on offense, where they only score 2.56 goals per game. 18. Florida Panthers ? 47.640 (18) A team playing better than their record (10-12), but can?t score (2.54 goals per game) and definitely can?t score on the power play (6.4%!!!) even though they take 32 shots a game. 19. Phoenix Coyotes ? 44.456 (28) Huge jump thanks to much improved play all over the ice. They?ve still give up more goals than they have scored though, and their special teams and team defense (33 shots against per game) haven?t been good. 20. Buffalo Sabres ? 43.944 (25) Ryan Miller hasn?t carried them like he did last year, and the offense hasn?t stepped up to the plate either (2.4 goals per game, 13.4% PP). Brutal in close games, winning only 35.7% of 1-goal games. 21. Calgary Flames ? 42.430 (11) Keeping Edmonton company at the bottom of the standings is never a desirable spot, but their power play is bad (14.7%), they give up 30 shots a game, and they win only 27.3% of their 1-goal games. 22. Nashville Predators ? 40.910 (22) Yet another team who can?t score (2.22 per game, 12.5% on the power play), but goaltending and defense have been good. Only 3-5 after regulation though. 23. Carolina Hurricanes ? 35.975 (21) By far the worst team in the faceoff circle (40.6%). Unlike the teams above, they can score, but they can?t defend (33.8 shots against) or keep the puck out of the net even strength or on the penalty kill (77.6%). 24. Anaheim Ducks ? 35.511 (30) Think they miss Scott Niedermayer? The goalies do, as they give up almost 35 shots a game. Special teams are good but not much else is. 25. Toronto Maple Leafs ? 33.929 (16) Remember that 4-0 start? How things have changed. As predicted before the season, this current group can?t score enough (2.22) to win games, despite pretty decent goaltending (2.74 goals against). Atrocious penalty kill, too. 26. Minnesota Wild ? 33.548 (22) One of the worst teams in the league 5-on-5, being outscored 41-30, which is being hidden by their power play (24.1%). They give up a whopping 7 more shots than they take per game. 27. Ottawa Senators ? 29.273 (27) Can?t score, can?t defend, can?t keep pucks out of the net, can?t do much of anything these days. 28. New Jersey Devils ? 29.257 (26) 9.9% on the power play. A league-worst 1.79 goals for per game. But hey, they?re 4-2 after regulation... 29. New York Islanders ? 16.599 (19) Allowing more than a full goal per game more than they score, but are brutal in 1-goal games (18.2%). Only 2.09 goals for per game, too. 30. Edmonton Oilers ? 13.181 (29) The kids have been fun to watch, just wait until they have another top pick. Nick is RealGM?s NHL Feature Writer.
