The Deal Was White for a Future Fourth
Basketball-Reference's player transaction record lists the November 3, 1980 trade directly: Seattle sent Golden State a future 1981 fourth-round pick for Rudy White. The selection ultimately landed at No. 76 in the 1981 draft and became Lewis Lloyd.
White Played Only 12 Seattle Games
White had appeared in four games for Golden State before the trade. After joining Seattle, he played 12 regular-season games and averaged 3.3 points, 0.9 rebounds and 1.5 assists in 13.8 minutes. Those 12 appearances were the final NBA regular-season games of his career. Seattle therefore received a very small direct return.
The Pick Became Lewis Lloyd
Golden State used the acquired fourth-rounder on Lloyd in June 1981. Lloyd played 16 games as a rookie in 1981-82, then appeared in 73 games in 1982-83. In that second season he averaged 9.4 points, 3.6 rebounds and 1.8 assists while starting 24 games. Across the two seasons, Lloyd gave Golden State 89 regular-season games. That is already substantially more realized value than Seattle received from White.
Golden State Also Received Compensation When Lloyd Left
On August 29, 1983, Lloyd signed with Houston as a veteran free agent. Basketball-Reference's transaction record states that Golden State received a 1985 second-round pick as compensation. That selection was later used on Bobby Lee Hurt. This review does not need to assign a large value to Hurt to decide the original trade. The compensation pick simply adds another downstream asset to a branch that had already produced 89 games.
Why Golden State Wins
Seattle received 12 low-minute White appearances and no documented downstream NBA asset from him. Golden State received 89 Lloyd games, including a useful 1982-83 rotation season, and later recovered a second-round compensation pick when Lloyd left for Houston.
Final Verdict
Warriors Win, B+/D. Golden State receives a B+ for the Lloyd production and later compensation pick. Seattle receives a D because White played only 12 games before his NBA career ended.
