The Boston Celtics won their show-and-prove matchup last week against the previously unbeaten Cleveland Cavaliers.

Welcome back to the world's first incontrovertible power rankings, where we have sorted the NBA's 30 teams into a perfect order.

Teams are competing and not blatantly exercising organizational priorities, and in a culture where we’re waiting for the next “trades we want to see” piece to drop, I like that NBA Cup games take place just after the glorified feel-out games that mark the opening weeks of the season and wrap up just before all of those new contracts become tradeable.

With the first five weeks of the season in the books, our latest NBA power rankings reveal who the 10 best and 10 worst NBA teams right now.

Despite a 2-2 week with two losses in the final seconds, the Houston Rockets (12-6) showed enough to hold at No. 5 in the NBA’s weekly power rankings.

The Jazz snapped a four-game losing streak with a win over the Knicks. Lauri Markkenen went off for 34 points. Collin Sexton has also had a positive season. He could be traded to a contender. Meanwhile, Cody Williams has had an inconsistent start to his season.

As Victor Wembanyam and the Spurs continue to rise up the NBA power rankings, Joel Embiid and the 76ers are on the verge of total collapse.

The last time we did NBA Power Rankings was after the first week of the season. Things have changed considerably since then. Philadelphia's season already looks lost while Golden State is far outpacing what we thought it would be.
