Welcome to theScore's biweekly NBA Power Rankings, where you'll find roughly 30 words on all 30 teams every other Tuesday throughout the season.

Houston can seemingly do no wrong. Their 9.3 net rating over the last 13 games (11-2) is 2.2 points better than any other team. Recent wins over Golden State, Cleveland, San Antonio, and Minnesota have come by an average of 17.2 points.

The Dubs look oddly human of late, going 4-3 in their last seven. Steve Kerr says his team is "mentally fried" and needs to get to the All-Star break for a rest.

At 21-4, the Raptors are the NBA's best home team, and with a favorable home-road split the rest of the season, they have a real chance to jump Boston for the East's No. 1 seed.

Despite not having Kyrie Irving (quad), Marcus Morris (hip), and Marcus Smart (hand) of late, the Celtics have handled their business against mostly meager competition, with some lucky breaks along the way.

Since the calendar flipped to 2018, only the Warriors have a more efficient offense than the Wolves. Backward for a Tom Thibodeau-coached squad, although their defense has shown some slight improvement.

The Spurs continue to defy all reason by producing the league's second-stingiest defense, despite starting two earthbound bigs and having their two-time Defensive Player of the Year suit up for just nine games. But they're just 9-9, with a bottom-10 offense, in 2018.

"Everybody eats" with John Wall sidelined. Washington leads the Association in assists (32.2) since he went down, and Tomas Satoransky has filled the void in the starting lineup quite nicely.

In winning six of eight since Jan. 22, Jamal Murray is shooting close to 48 percent from deep, and Nikola Jokic is almost averaging a triple-double.

It's a tiny sample that's come against a pillowy slate, but the Bucks are 6-1 - with the league's best defense (!) - since interim head coach Joe Prunty took over for Jason Kidd. Dialing back the team's aggressive trapping scheme has helped.

We thought we had the Thunder all figured out. That is, until they followed up an eight-game winning streak with four straight losses to the likes of the Lakers and Wall-less Wizards.

The Blazers have followed up their first four-game winning streak of the season with a three-game losing streak. Portland needs wins now as they've got a tough schedule in March and April.

Few teams are as reliant on their stars as the Pacers are on Victor Oladipo. Their loss Monday to the Wizards dropped them to 0-6 without him this season. With him, they're 30-19, which would be the NBA's sixth-best record.

Kevin Love is hurt, their defense is still abysmal, and there's apparently little trust on both ends. Cleveland's aura of invincibility is completely shattered.

Miami's season has been up and down like a toilet seat. Some quality wins, but now a four-game losing streak punctuated by a home loss to the lowly Orlando Magic.

The Pelicans are 1-4 since DeMarcus Cousins went down, and are just a half-game up on the Clippers for the final Western Conference playoff spot. But six of their next seven opponents are East teams, against whom they're 14-6 this season.

Utah owns both the No. 1 offense and defense during their six-game surge. The Warriors, who were at full strength, took a giant haymaker to the chin at Vivint Smart Home Arena last week.

Guess who's won four straight and is knocking on the eighth seed's door? The Pistons haven't lost since acquiring Blake Griffin.

Joel Embiid is playing back-to-backs, a huge development for the playoff-hopeful Sixers, who are an elite team (plus-8.7 net rating) with their star center on the floor, and a woeful one (minus-5.7) when he's not. They have seven back-to-backs remaining this season.

Not to be outdone, the Clippers are also unscathed at 2-0 with Tobias Harris in the lineup following the Griffin deal. Harris is averaging 21.5 points and 4.5 boards in his new surroundings.

Dwight Howard is posting his highest usage rate since 2014-15, but also the second-lowest true shooting percentage of his career.

It's weird that the Lakers are shopping Julius Randle, because he's 23 and has probably been their best player this year. In 19 games as a starter, he's averaging 16.6 points, 9.2 rebounds, and 2.7 assists on 59.8 percent true shooting.

Faulty execution late in games is killing the Knicks. Being unable to hold off the lowly Hawks doesn't bode well for a late postseason push in The Big Apple.

With another lottery pick out the door (this time to the Cavaliers), the Nets are tinkering. Tyler Zeller was moved Monday, is DeMarre Carroll next?

The Grizzlies' recent draft history has been ugly, but they appear to have found something in second-rounder Dillon Brooks. On top of his solid perimeter defense, the rookie wing is averaging 11.7 points on .486/.426/.727 shooting in 2018.

Dirk Nowitzki is reaching more milestones, and rookie Dennis Smith Jr. will be dunking over All-Star Weekend. Dallas remains a competitive bunch, but close losses are still losses, and they're adding up.

Ah, the sweet stench of correction. The Bulls have lost seven in a row and are shooting a league-worst 40.5 percent from the floor in that span. That's a long way from the team that won seven straight in December and had some talking playoffs.

After a rough start to his career, Josh Jackson appears to be figuring things out. He looks far more comfortable shooting and making plays off the bounce, and the Suns have actually been a net positive with him on the floor in the new year.

Atlanta is averaging 13,951 fans per home game, making them the only team not above the 15,000-fan mark. Just wait until they host a team from the West, because the Hawks seem to find success under those circumstances.

Some categories in which the Kings are last in the NBA: Net rating, true shooting percentage, free throws attempts, and free throws made. Only the Grizzlies have scored fewer total points this season.

Mario Hezonja is finally starting to resemble the player the Magic thought they were getting with the fifth pick in 2015. Since they declined his fourth-year option, it'll be interesting to see if the team tries to move him at the deadline.
