Chicago acquired Bob Kauffman and Seattle's 1971 third-round pick on September 5, 1969 for Bob Boozer and Barry Clemens. The pick became Clifford Ray, who gave the Bulls three seasons and 235 regular-season games as a high-level rebounder before becoming part of the 1974 Nate Thurmond trade. Kauffman added 64 games for Chicago before being delivered to Philadelphia as future consideration from the earlier Chet Walker deal. Seattle also received substantial value: Boozer averaged 15.2 points and 8.7 rebounds in 82 games, while Clemens played 238 games over three seasons. The completed returns are close enough to support an even verdict.
