This June 7, 1977 Cleveland-Buffalo record is not a supported NBA transaction. The legacy archive record says Cleveland sent Jim Cleamons to Buffalo for John Gianelli and a 1977 first-round pick, but the Cavaliers, Braves and league transaction ledgers record no such exchange. Cleamons remained a Cleveland player until October 10, 1977, when he signed with New York as a veteran free agent and the Cavaliers received Walt Frazier as compensation. Gianelli likewise remained with Buffalo until September 2, 1977, when the Braves traded him to Milwaukee for a 1979 first-round pick that became Roy Hamilton. Cleveland's 1977 draft history contains no first-round selection; its first pick was No. 33 Eddie Jordan in round two. Buffalo's documented June 7 move was its separate first-round-pick exchange with Milwaukee. The legacy Cleamons-Gianelli-pick record is therefore retained only as provenance and receives no winner or grades.
No separate canonical grade is recorded for Cleveland Cavaliers, LA Clippers.
The legacy archive entry claims Cleveland traded Jim Cleamons to the Buffalo Braves on June 7, 1977 for John Gianelli and a 1977 first-round pick. Basketball-Reference's Cleveland transaction log does not contain that move. Buffalo's transaction log does not contain it either, and the league-wide 1976-77 transaction ledger has no Cleveland-Buffalo transaction involving Cleamons or Gianelli on June 7.
Cleamons's own transaction history directly contradicts the legacy trade. Basketball-Reference records his 1972 move from the Lakers to Cleveland, then no transaction until October 10, 1977. On that date the New York Knicks signed Cleamons as a veteran free agent and sent Walt Frazier to Cleveland as compensation. The Knicks' team ledger and the 1977-78 league ledger independently record the same free-agent compensation transaction. A June sale to Buffalo would be incompatible with Cleveland still owning Cleamons's veteran-free-agent compensation rights in October.
Gianelli's transaction history creates the same contradiction on the other side. The Knicks had traded Gianelli and cash to Buffalo for Bob McAdoo and Tom McMillen on December 9, 1976. He remained a Braves asset through the summer. On September 2, 1977, Buffalo traded Gianelli to Milwaukee for a 1979 first-round pick that became Roy Hamilton. Milwaukee's transaction ledger and the 1977-78 league ledger both preserve that September move. There is no intervening Cleveland transaction.
Cleveland's draft history shows no Cavaliers first-round selection in the 1977 draft. The team's first listed choice was Eddie Jordan at No. 33 in round two. Buffalo's actual June 7 transaction involved a different first-round branch: the Braves sent the pick that became No. 3 Marques Johnson to Milwaukee for Swen Nater and the pick that became No. 13 Tate Armstrong. Three days later Buffalo moved the Armstrong pick to Chicago for the second-round pick used on Larry Johnson. Those documented pick movements leave no supported Cleveland first-round outcome matching the legacy archive entry.
Each named component belongs to a real 1977 transaction history, but not to the transaction represented here. Cleamons later produced Walt Frazier compensation for Cleveland. Gianelli later produced a 1979 first-round pick for Buffalo. Buffalo also made multiple first-round-pick moves around the June draft. The legacy archive entry appears to have combined unrelated assets and timing into a Cleveland-Buffalo exchange that the surviving primary ledgers do not support.
Deleting the record would erase provenance for the original legacy import and make the source-cleanup trail harder to audit. Leaving it active would be worse: it would invent a trade, assign both players to teams they never joined through this mechanism, and introduce an untraceable first-round pick into Cleveland's history. The correct archive treatment is to retain the identifiers and original asset structure privately while excluding the record from active candidate analysis.
Record Superseded. No winner and no grades are assigned. Confidence is high because the Cleveland, Buffalo and league transaction logs all omit the alleged June 7 exchange, while the later Cleamons-to-New York and Gianelli-to-Milwaukee movements are independently documented by team, league and player ledgers. The superseded entry is retained for provenance but excluded from graded results.
