This December 10, 1956 Slater Martin-for-Willie Naulls listing is retained only as legacy source provenance. Basketball-Reference's St. Louis Hawks and New York Knicks transaction logs both place the exchange on December 12, 1956, as does the franchise executive record. The two rows describe the same players moving between the same teams, so keeping both would double-count one NBA trade. The December 10 record is therefore superseded, while the December 12 record remains the canonical transaction for full source-backed analysis.
No separate canonical grade is recorded for New York Knicks.
The surviving St. Louis, New York and league transaction records do not support a separate Slater Martin-for-Willie Naulls trade on December 10, 1956. The same player package is documented on December 12, so this earlier legacy row cannot stand as an independent transaction.
TradeVerdicts already stores the verified December 12 exchange as the canonical Martin-Naulls trade. That record matches the team transaction pages and executive ledger, while the December 10 date survives only through the older source lineage.
Martin became an immediate St. Louis All-Star and helped the Hawks reach the NBA Finals, while Naulls developed into a four-time All-Star in New York. Those outcomes belong to the verified December 12 transaction and should not be counted twice.
The route stays in the private archive for provenance, but it is excluded from public/indexable treatment and hindsight grading. No winner or team grades are assigned because the duplicate date itself is not a completed trade.
