By virtue of their positioning toward the top of our NBA power rankings, the league's best teams are obviously talented and accomplished.

But they are not opportunistic.

Almost anyone from last week's top six had a chance to snatch the No. 1 spot from the Golden State Warriors, who are still without Stephen Curry and, perhaps not unrelated, scored just 81 points in their biggest brickfest in years this week.

But instead of seizing their chance at glory, the Cleveland Cavaliers, Houston Rockets, Toronto Raptors and Boston Celtics decided it'd be better to drop games while in some cases also suffering key injuries.

So much for drama at the top.

As always, these rankings consider advanced stats, win-loss records and health (plus some gut feeling) to organize all 30 teams into an order reflecting the league's current hierarchy. Recent play counts a bit extra, but full-season numbers are still relevant.
