Professional career

Williams was a first-round draft choice of the Indiana Pacers in 1981, where he played from 1982 to 1989 and had his most productive years.

He was traded to the Dallas Mavericks midway through the 1988-1989 season on February 22 in exchange for forward Detlef Schrempf.

In 1992, he was signed by the New York Knicks, where he spent seven years backing up perennial All-Star Patrick Ewing. Williams played one game (31 minutes) for the Toronto Raptors in 1996 before being waived and quickly returned to the Knicks. The team made the 1994 and 1999 NBA Finals, with Williams serving as a team leader.

After the 1999 Finals, Williams retired at the age of forty-one after six regular season games and eight playoff games in 1999. Four years later, he returned to the Knicks as an assistant coach. He worked under head coaches Don Chaney and Lenny Wilkens. When Wilkens resigned in 2005, Williams took over as head coach.

On July 26, 2005, Larry Brown was hired as the head coach of the Knicks, thus ending Williams' head coaching tenure. Williams was the acting head coach of the Knicks for the final two games of the 2005-2006 season, when illness kept Larry Brown away from the bench for the final two games of his Knicks career.

After that season, Brown was fired by the Knicks and replaced as head coach by Isiah Thomas. Williams worked as an assistant coach under Thomas and Mike D'Antoni, and continued to be in the coaching staff under Mike Woodson until Phil Jackson fired the entire staff in 2014. He has coached for the Knicks' NBA Summer League team.

On March 26, 2015, Williams was hired as the assistant coach of the WNBA's New York Liberty.
