David Greenwood, the No. 2 pick in the 1979 draft who played the first six of his 12 NBA seasons for the Chicago Bulls, died Sunday at 68.

Before Michael Jordan arrived in Chicago in 1984, Mr. Greenwood was among the Bulls’ core players. After six seasons, the Bulls traded him in 1985 to the Spurs for future Hall of Famer George Gervin.

American, David Greenwood had a 12-year NBA career and was a member of the Detroit Pistons' title team in 1990.
