The September 16 Cash Sale Is Unsupported
The Knicks, Zephyrs and league ledgers do not show a September 16, 1962 cash transaction for Cliff Luyk. They instead agree that Luyk had already been traded to Chicago six days earlier as part of the Gene Conley deal.
Luyk’s Player History Confirms the September 10 Move
Luyk’s transaction record shows the September 10 trade and no immediate return to New York. He never appeared in an NBA game, and the surviving ledgers provide no evidence of the separate cash reversal described by the legacy row.
Counting Both Rows Would Duplicate One Asset Movement
The verified Conley transaction is already represented canonically. Treating the September 16 line as another completed trade would send the same player back across the same team pair without support from either team ledger or the league transaction record.
Preserve the Provenance, Not a Fictional Grade
This route is retained as legacy provenance so the source conflict remains auditable. It is structurally superseded rather than graded as a second Knicks-Zephyrs trade, and no team grade should be invented for a transaction the evidence does not establish.
Final Resolution
Record Superseded This September 16, 1962 New York-Chicago cash transaction for Cliff Luyk is retained only as legacy provenance. Basketball-Reference's Knicks, Zephyrs and league transaction ledgers do not record a September 16 deal.
