Williams signed with the Nuggets Saturday and played for them in a 120-104 loss to the Philadelphia 76ers Saturday night, scoring seven points.
Williams, a guard, reportedly has been signed through the rest of the season.
After being cut by the Spurs, Williams had said: "This is particularly frustrating, because I was playing the best ball of my NBA career. I was shooting just under 50 percent from the field [48 percent] and making more than half my three-point shots. I finally had my confidence back.
"If I hadn't been performing, it would have been understandable. What it came down to was money: I was the only one on the Spurs' roster without a guaranteed contract."
Williams, 6 feet 7, averaged 7.8 points in 17 minutes per game with San Antonio.
* PISTONS: Chuck Daly has led the Detroit Pistons to two straight NBA championships, so his lack of excitement over his 400th NBA coaching victory can be excused.
"I started off 9-31 in this league, so that's persistence," Daly said before No. 400 over the New Jersey Nets Saturday night. "Every one's sweeter than the last, but I didn't even know it was No. 400 until someone pointed it out to me."
Had Daly followed through on reported plans during the off-season to leave the Pistons for NBC, this milestone wouldn't have occurred.
"I wasn't ready to give up coaching," he said. "This team had won two titles. You would second-guess yourself forever if you walked away without trying to win a third."
In his eighth season with Detroit, Daly has built and sustained a winner. Of his 400 wins, 391 have been with the Pistons, the other nine in a brief stint with the Cleveland Cavaliers.
* BUCKS: Del Harris got his 300th NBA coaching victory Saturday night and said it was a tribute to his ability to hold a job in the league.
"When you win 300 NBA games, it shows at least you've been able to stick around, and that's not easy to do," said Harris, whose eight-season record with the Bucks and Houston Rockets is 300-306.
* 76ERS: Ten months after Wilt Chamberlain ended a 22-year grudge against his former team, the club said yesterday it will retire his jersey in March.
The Sixers will honor Chamberlain, 54, on March 18 in a pre-game ceremony against the Orlando Magic. Chamberlain friend and Philadelphia attorney Michael Richman said that the Hall of Fame center would appear at the game to see No. 13 lifted to the Spectrum's rafters.
Chamberlain, a Philadelphia native, played for the 76ers from 1965 to 1968. In 1967, he led the Sixers past his former team, the San Francisco Warriors, in the NBA finals, making Philadelphia the only club other than the Boston Celtics to win the title during the 1960s.
Chamberlain's longtime grudge against the Sixers began in 1968, when he agreed to a trade to the Los Angeles Lakers, where he played for five seasons.
Chamberlain claimed that at the time of the deal he was promised part-ownership of the 76ers by former owner Ike Richman. But Richman died before an agreement could be formalized.
Billy Cunningham, Hal Greer, Bobby Jones and Julius Erving have had their numbers retired by the Sixers.
