NBA Power Rankings: The Lakers and Warriors are powerfully charging toward playoff spots, the Cavaliers are heating up once more, and the Bucks are steadily climbing.

A storm is brewing in the Western Conference. While the Oklahoma City Thunder are clearly the favorites—as they rightfully deserve to be—the power dynamics below them are shifting rapidly. The Memphis Grizzlies and Houston Rockets, despite their stellar season, are now losing ground, whereas two California powerhouses, energized by key trade deadline acquisitions, are on the rise: the Los Angeles Lakers and the Golden State Warriors.

Luka Dončić and the Lakers have been on an unstoppable run, winning seven straight games while posting the league’s top defensive rating since February 1. LeBron James appears to be defying age—earning Western Conference Player of the Month for February—and his numbers have surged since Dončić arrived. In just six weeks, the Lakers have vaulted from a borderline playoff team to the No. 2 seed.

The Warriors have also staged a comeback, though not quite to the same degree. They were struggling near the Play-In cutoff before February, but a 9-2 run following the acquisition of Jimmy Butler has moved them up to No. 6, comfortably above the Play-In line. Stephen Curry, rejuvenated much like LeBron, is now averaging 29 points and seven assists on impressive shooting splits (51/43/89) since the trade.

At this point, aside from the Oklahoma City Thunder, both the Lakers and the Warriors stand as some of the most formidable teams in the Western Conference.

The only team that can claim superiority over the Thunder is the Cavaliers, who remain at the top this week as their current winning streak reaches 12 games. As the first team to secure a playoff berth, the Cavs have repeatedly demonstrated their ability to outplay opponents, and they’ve become only the second team in NBA history—after the 2006-07 Dallas Mavericks—to notch three separate 12-game winning streaks in a single season.

In the Eastern Conference, the Milwaukee Bucks have been making significant noise following the All-Star break. Their recent surge moved them into the No. 4 seed—a position that would secure home-court advantage in the first round. Despite a roller coaster season, the Bucks benefit from having Giannis Antetokounmpo, a player no postseason opponent wishes to face. In fact, Milwaukee was this week’s biggest mover, leaping four spots to land at No. 9.
