NBA POWER RANKINGS: Where all 30 teams stand 4 weeks before the playoffs

There's no doubting the Warriors' dominance, but for perhaps the first time all season, things are getting interesting.

The Spurs found a weakness in the Warriors, handing them their first loss to a top-five team all season. And while the next level of contenders like the Cavaliers, Thunder, and Clippers are struggling, several teams, particularly in the East, are surging, making for an interesting postseason.

With about four weeks left in the regular season, the playoffs are around the corner, and the race is on.

Note: Offensive and defensive ratings measure points scored and points allowed per 100 possessions. League rankings are next to ratings.
