NBA Power Rankings: Warriors back on top, Raptors make a move

What a difference a week makes in the NBA, as the suddenly slipping Houston Rockets have given up No. 1 to a familiar foe.

Thanks to their Christmas Day win over the Cleveland Cavaliers, the Golden State Warriors are back in the top spot this week as Houston dips to No. 2 following three straight losses. In the Eastern Conference, three losses in four games by the Boston Celtics have paved the way for the Toronto Raptors -- winners of 12 of their past 13 games -- to take the conference lead and leapfrog Boston into the top five of our rankings.

Every week throughout the regular season, our panel (ESPN's Kevin Arnovitz, Amin Elhassan and Ramona Shelburne, The Undefeated's Marc J. Spears and FiveThirtyEight's Chris Herring) will rank the league's 30 teams from top to bottom, with research notes on each team provided by ESPN Stats & Information.

Previous rankings: Week 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1

1. Golden State Warriors
2017-18 record: 27-7

Draymond Green recorded his 20th career triple-double Monday, tying the Warriors' record held since the early 1960s by Tom Gola. According to the Elias Sports Bureau, among the 24 players who have racked up at least 20 triple-doubles in the NBA, Green is the only one whose career scoring average (9.1) is below 10 points per game. -- Jim Merritt

2. Houston Rockets
2017-18 record: 25-7

According to Elias, James Harden is only the second player over the past 20 seasons to score as many as 130 points during a three-game losing streak for his team. The other player was Russell Westbrook, who generated 135 points over a three-game skid for the Thunder in March 2017. -- Jim Merritt

3. Cleveland Cavaliers
2017-18 record: 24-10

The Cavs were held to 31.8 percent shooting in their Christmas Day loss to the defending champion Warriors. In fact, it was the lowest percentage by a Warriors opponent in nearly four years: Charlotte shot 31.2 percent from the field on Feb. 4, 2014. -- Jim Merritt

4. Toronto Raptors
2017-18 record: 23-8

The hottest team in the NBA? That's the Raptors, who have won 12 of their past 13 games. Toronto leads the league in defensive efficiency during this span after ranking 14th over its first 18 games. -- Michael Schwartz

5. Boston Celtics
2017-18 record: 27-10

The Celtics, in their 72nd season, finally hosted their first Christmas Day game on Monday. The franchise had previously played 30 Christmas Day games, all without a true home game, and fell to 14-17 all time after its loss to the Wizards. -- Jim Merritt

7. Minnesota Timberwolves
2017-18 record: 21-13

8. Oklahoma City Thunder
2017-18 record: 19-15

During OKC's Christmas Day win, Russell Westbrook, Paul George and Carmelo Anthony combined for 75 points while making 54.9 percent of their field goal attempts. According to Elias, in no other game this season have Westbrook, George and Anthony combined to score as many points while also hitting as high a percentage of their shots. -- Jim Merritt

9. Washington Wizards
2017-18 record: 19-15

The Wizards franchise has now played 23 games on Christmas Day, and, according to Elias, John Wall is the only player to produce a 20-point, 10-assist game in any of them -- and he now has done that twice after Washington's win over Boston on Monday. -- Jim Merritt

10. Milwaukee Bucks
2017-18 record: 17-14

Eric Bledsoe had arguably his best game as a member of the Bucks on Friday against the Hornets, recording his first 20-point, 10-assist game with the team.

2017-18 record: 18-14

14. Portland Trail Blazers
2017-18 record: 17-16

On Saturday, the Trail Blazers won their 14th straight game against the Lakers, which is tied for the second-longest winning streak all time by any team against the Lakers. Only the Celtics had a longer streak -- back in the 1950s. -- Michael Schwartz

15. New Orleans Pelicans
2017-18 record: 17-16

The Pelicans play back-to-back games against the Mavericks and Knicks this week and are 3-2 on zero days' rest this season. Last season, the Pelicans went 5-12 on zero days' rest. -- Jose De Leon

18. Utah Jazz
2017-18 record: 15-19

Jazz rookie Donovan Mitchell scored at least 25 points for the ninth time this season in Saturday's loss to the Thunder. That's four more such games than the next-closest rookie: the Lakers' Kyle Kuzma. -- Michael Schwartz

2017-18 record: 12-20

2017-18 record: 11-21

Following Tuesday's road game against the Clippers, the Kings begin a six-game homestand against the Cavaliers on Wednesday, tied for their longest of the season.
