Denver acquired veteran offensive tackle Harold Olson from…

The September 1, 1963 Buffalo-Denver transaction is well supported at the player-movement level but remains unresolved on the compensation side. Pro Football Archives records Harold Olson moving from Buffalo to Denver on that date, and NFL career records show the same team sequence: Olson played all 14 games for Buffalo in each of 1960, 1961 and 1962 before appearing in all 14 Denver games in both 1963 and 1964. He was not a marginal acquisition. Pro Football Reference credits him with first-team All-Pro recognition in 1962, his final Buffalo season, so Denver was acquiring an established AFL tackle. The compensation wording is less precise. Pro Sports Transactions' 1964 AFL draft ledger describes Buffalo as receiving a 'high draft player' and explicitly flags two possible downstream identities: the Bills' No. 25 selection, George 'Butch' Byrd, or No. 81 Bobby Smith. Both players were on Buffalo's 1964 roster, and Byrd in particular developed into a major Bills defensive back, but the reviewed transaction ledger does not conclusively tie either player to the Olson exchange. That uncertainty is too important to ignore. Assigning Byrd to this trade would transform the historical value judgment, while assigning Smith would produce a much different result. TradeVerdicts therefore removes the old wording that implied one likely choice and instead records only the source-backed fact that Buffalo received a high 1964 draft player whose exact identity cannot be established safely from the surviving public record. Denver's realized return is clear enough: Olson gave the Broncos 28 regular-season games over two seasons before his career ended. Buffalo's exact realized return cannot be measured without selecting one of two disputed draft identities. The existing Even Trade verdict and C/C grades are retained as the conservative source-safe treatment rather than crediting either club with an unverified downstream player. Confidence is medium because the trade date, teams, Olson's career path and the existence of draft compensation are well supported, while the identity of Buffalo's return remains unresolved.
