LOS ANGELES — David Greenwood, who was one of the Bulls’ core players as the Michael Jordan era was getting underway, has died. He was 68.

Mr. Greenwood was one of coach John Wooden’s last recruits at UCLA and would win an NBA championship with Detroit during a 12-year pro career, he died Sunday in Riverside, California, after battling cancer, the school said Wednesday, citing family members.

After a standout career at Verbum Dei High in Los Angeles, Mr. Greenwood began his college career at UCLA just months after Wooden’s surprise retirement announcement in March 1975.

He averaged 14.8 points and 8.7 rebounds in 118 games as a four-year starter in Westwood. The Bruins had a record of 102-17 and won the league title in each of his four seasons. He was a two-time league player of the year who helped the Bruins to the 1976 Final Four.

Mr. Greenwood earned first-team All-America honors as a junior and senior, becoming UCLA’s first player to do so since Bill Walton in 1972-74. He still ranks fourth on the school’s career rebounding list.

He was the second overall pick in the 1979 NBA draft. The Bulls lost the coin toss to the Los Angeles Lakers, who drafted future Hall of Famer Magic Johnson at No. 1, having acquired the pick in a trade with New Orleans.

Before Jordan arrived in Chicago in 1984, Mr. Greenwood, Reggie Theus and Orlando Woolridge were the Bulls’ core players. After six seasons, the Bulls traded Mr. Greenwood in 1985 to San Antonio in exchange for future Hall of Famer George Gervin.

Mr. Greenwood also played for San Antonio, Denver and Detroit, coming off the bench to help the Pistons beat Portland to win the 1990 NBA championship.

Mr. Greenwood later coached at his high school alma mater, leading Verbum Dei to state titles in 1998 and 1999.

He is survived by son Jemil and daughter Tiffany as well as his brother Al, sister Laverne and former wife Joyce.
