Gerald Wallace and Brook Lopez each scored 15 for the Nets, who have lost four of five.
There was a brief skirmish in the fourth quarter that resulted in four technical fouls, but that was the most fight the Nets put up in a disappointing performance on the national stage of the Christmas opener. Williams had only 10 points on 3-of-7 shooting and Joe Johnson, his partner in a high-priced backcourt, shot 4 of 14 for his 12 points.
In Tuesday’s final game the Los Angeles Clippers stretched their winning streak to 14 games by defeating the Denver Nuggets 112-100, Jamal Crawford scoring 22 points and Matt Barnes 20.
The Clippers, who have reached the playoffs only once since 1997, improved to 22-6, taking the best record in the league after Oklahoma City defeat earlier on Tuesday.
Chris Paul added 14 points and a game-high eight assists for the Clippers, the most of any Los Angeles starter as the hosts outscored Denver 42-22 in the second quarter for a 67-48 half-time lead and cruised through the second half.
Blake Griffin had 13 points, six rebounds and six assists for the Clippers
Jordan Hamilton and Kosta Koufos each scored 16 points to lead the Nuggets while Ty Lawson added 15 for Denver.
