and became the head coach of the University of Kansas Jayhawks basketball team replacing former North Carolina assistant and UCLA head coach Larry Brown, who had taken the position as head coach of the NBA's San Antonio Spurs. He was hired just months after the Danny Manning-led Jayhawks won the 1988 NCAA championship. Weeks after Williams took the position, KU was placed on probation for violations that took place prior to his arrival. As a result, the Jayhawks were barred from postseason play for the 1988–89 season. Williams coached 15 seasons at Kansas (from 1988 to 2003). During that time he had a record of 418–101, a .805 winning percentage. At the time of his departure, he was second on Kansas' all-time wins list behind only Phog Allen; he has since been passed by current coach Bill Self. Williams' Kansas teams averaged 27.8 wins per season. Kansas won nine regular-season conference championships over his last 13 years. In seven years of Big 12 Conference play, his teams went 94–18, capturing the regular-season title in 1997, 1998, 2002 and 2003 and the postseason tournament crown in 1997, 1998 and 1999. In 2001–02, KU became the first, and so far only, team to go undefeated (16–0) in Big 12 play. In 1995–98, Kansas was a combined 123–17 – an average of 30.8 wins per season. Williams' teams went 201–17 (.922) in Allen Fieldhouse, and won 62 consecutive games in Allen from February 1994 to December 1998. Kansas was a regular in the Associated Press Top 25 from 1991 to 1999, placing in the poll for 145 consecutive weeks. Williams' teams were ranked in the Top 10 in 194 AP polls from 1990. Kansas led the nation in field goal percentage and scoring in 2002 and in scoring margin in 2003; they held opponents to the lowest field goal percentage in the country in 2001 (37.8 percent); led the nation in winning percentage in 1997 and 2002; shot better than 50 percent from the floor for the season seven times; and led the country in field goal percentage in 1990 at 53.3 percent, and in 2002 at 50.6 percent; shot a combined 49.4 percent from the floor in 15 seasons; led the nation in assists in 2001 and 2002 and was seventh in the nation in 2003; scored 100 or more points 71 times (once every 13 games); averaged 82.7 points per game
