Williams had 27 points, 12 assists and 6 rebounds, but the Nets allowed the Sixers to shoot 52.6 percent from the field and saw their three-game winning streak come to an end with a 106-97 loss at Wachovia Center.
The Nets (37-27) are 21-4 against sub-.500 teams (at time of game played). The Sixers (24-39) came in having lost 12 of their last 13 games.
Williams reached the 10,000-point club in the fourth quarter. He had 14 points in the third, and recorded his 15th double-double of the season.
Spencer Hawes destroyed the Nets on the interior, amassing 24 points and 10 rebounds.
CLOSING THE GAP: The Nets trailed by as many as 14 in the third quarter, but closed the period on a 7-0 run to make it 82-75 Sixers going into the fourth.
SECOND IS THE WORST: The Nets were outscored 29-18 in the second quarter as the Sixers took a 53-46 lead to the break. Philadelphia shot 63.2 percent in the period.
HOT STARTS: Lopez had 14 first-quarter points on 7-for-9 shooting, while D-Will stuffed the stat sheet in the opening 12 minutes to the tune of seven assists and four rebounds.
TIGHT 10: Interim coach P.J. Carlesimo did play 10 players instead of nine -- albeit briefly, when he gave MarShon Brooks two minutes late in the second quarter. Gerald Wallace, who continues to struggle offensively, going 2-for-8 from the field, was benched for the entire fourth.
WELL-TRAVELED: Several Nets season-tickets holders made the trip down 95 to watch their favorite team in Philly. “Brook-lyn!” chants were heard loud and clear throughout the first half.
