The Colonels' lead over Virginia ballooned to 13, while the Stars opened up a 7½-game margin over Indiana. New York, third in the East, fell nine games out of second with three losses in a row despite Rick Barry's barrage of 47, 50 and 30 points, but Dallas, the third-place team in the West, crept within 5½ of second with a six-game winning siring.

Meanwhile, Boston dropped four of five, including a 117-109 loss to Milwaukee that broke the nine game Celtic string.
