The Warriors did not make a second transaction with Chicago on the same day. Team and league ledgers show one exchange in which Golden State sent Thurmond to the Bulls and received Clifford Ray, Chicago's 1975 first-round pick that became Joe Bryant, and cash. Keeping both legacy archive entrys active would double-count the same player and pick movements. The superseded entry is retained for provenance but excluded from graded results.
No separate canonical grade is recorded for Chicago Bulls, Golden State Warriors.
This Golden State row is the opposite-team import of the same September 3, 1974 Nate Thurmond transaction already preserved in the Chicago canonical record. Both rows describe the same date, teams and asset movement: Thurmond to Chicago, with Clifford Ray, Chicago’s 1975 first-round pick and cash going to Golden State. The source-led audit found no second same-day transaction.
Basketball-Reference’s Warriors, Bulls and league transaction pages all describe one September 3 exchange. Chicago acquired Thurmond. Golden State acquired Ray and the 1975 first that became No. 14 Joe Bryant, while Chicago historical material supports cash as part of the consideration. Those sources corroborate the surviving Chicago canonical record rather than establishing a separate Warriors-side trade.
Leaving both imports as independently graded transactions would count Thurmond, Ray, the same first-round pick and the same cash twice. It would also distort player relationship pages, team-pair histories and aggregate trade counts. The Golden State import adds source provenance, but it cannot receive a separate winner or grades without scoring one economic event two times.
The surviving canonical transaction is nba-trade-chi-1974-0039. This Golden State row is retained privately to preserve the independent source intake and audit trail. Its status is structural supersession, not a negative evaluation of either team’s real 1974 trade.
Record Superseded — duplicate canonical import, no separate winner and no team grades. The September 3, 1974 Nate Thurmond exchange is already represented by nba-trade-chi-1974-0039. Grading this Golden State import independently would double-count the same transaction.
