Like most folks out there, the NBA takes it relatively easy during the heart of the holiday season. The entire league took off Christmas Eve, and only 10 took to the court on Christmas Day.
You could argue that at least two teams (New York Knicks and Brooklyn Nets) were still so slogged on eggnog that they didn't even show up to the arena for their games.
And that at least one—the Indiana Pacers, who had themselves a pretty great week—should've been active during the biggest day on the regular-season calendar in the Association.
That being said, a light week of action doesn't necessarily correlate to stagnation in the power rankings from week to week. There was still plenty of jostling and jockeying among the league's hierarchy, albeit without the sort of dramatic movement that you might see in a normal, jam-packed week.
But don't take my word for it. Why don't you see for yourself?
