Golden State sold Jo Jo White's player rights to Kansas City on September 10, 1980 for an undisclosed cash return. White played 13 games for the Kings, averaging 6.4 points, 2.8 assists and 18.2 minutes before announcing his retirement on November 3. The Warriors received no on-court asset, but they did receive cash for a veteran who had already completed his final Golden State season. Because the sale amount is undocumented, the realized-value gap should stay modest: Kansas City got limited rotation minutes, while Golden State monetized rights it no longer planned to use.
Basketball-Reference records the September 10, 1980 transaction as a sale of Jo Jo White's player rights from Golden State to Kansas City. The Kings transaction ledger confirms the acquisition. The canonical TradeVerdicts record describes the return as cash. The reviewed transaction sources do not provide the amount, so this review preserves the cash asset but does not invent a dollar value.
White appeared in 13 regular-season games for the Kings. He logged 236 minutes and averaged 6.4 points, 2.8 assists and 1.6 rebounds in 18.2 minutes per game. That made him a short-term reserve rather than a major rotation addition. He still produced actual NBA minutes, which gives Kansas City a concrete realized basketball return from the purchase. Contemporary transaction research compiled by the Association for Professional Basketball Research records White announcing his retirement on November 3, 1980. That ended his NBA career and limited the Kings' return to those 13 games.
The Warriors' side is harder to quantify because the sale price is not documented in the reviewed public ledgers. Golden State had already received 107 regular-season games from White across parts of the previous two seasons before this transaction. This review does not re-credit those games here because they occurred before the September 1980 sale. The relevant return is only the cash received for his rights. That is still realized value, but without an amount there is no defensible way to compare it precisely with Kansas City's 13 games.
The Kings received measurable on-court production, even if it lasted less than a month of the regular season before White retired. Golden State converted an asset it no longer intended to use into cash. The unknown sale amount prevents a harsh grade, but it also prevents the Warriors from matching Kansas City's documented playing value on source-backed evidence.
Slight Kings Edge, C/C-. Kansas City receives a C for 13 games and 236 minutes from a veteran guard before retirement. Golden State receives a C- because the club realized cash value from the rights, but the amount is undocumented and cannot be scored as more than a limited return.
