One of the low-key hilarious lines of the classic 1971 version of Willy Wonka & The Chocolate Factory is delivered by Charlie's schoolteacher, played by a perfectly deadpan David Battley:

"I've just decided to switch our Friday schedule to Monday, which means that the test we take each Friday on what we learned during the week will now take place on Monday before we've learned it. But since today is Tuesday, it doesn't matter in the slightest."

This otherwise random blast from the past is relevant because, in case you haven't noticed, we've moved our NBA Power Rankings from Friday to Monday! And if you're reading this on Tuesday, it doesn't matter in the slightest.

Anyway, I'm sure not all of you showed up for quotes from Mr. Turkentine, so let's get on with the rankings for this week (well, actually 10 days), which saw a new No.1 that is also an old No. 1. The Boston Celtics reclaimed the top spot with which they've become familiar over the past couple of seasons, putting up a perfect week while last edition's top dog, the Denver Nuggets, fall ever so slightly due to a loss on Sunday night.

Both teams are getting pressure from underneath, as the swelling magma of the red-hot Philadelphia 76ers and Sacramento Kings are burning at the heels of the league's top two teams. Making leaps this week are the soaring Atlanta Hawks, who jumped a whopping 13 spots, and the Oklahoma City Thunder, who enter the top 10 after being viewed as an almost certain tank candidate to begin the season. You just never know.

On the other side are the unfortunate Indiana Pacers, who couldn't combat the absence of star point guard Tyrese Haliburton and have dropped six games in a row. Falling eight spots are the New York Knicks, whose defensive acumen evaded them over the past handful of games.
