Chronological Timeline
Trade 1 of 4
Buffalo Bills received 1967 sixth round pick (#149-Bill Wilkerson) and Dave Costa (a) from Oakland/Las Vegas Raiders for Bill Laskey and 1967 sixth round pick (#155-Rick Egloff). The recorded outcome favors Oakland/Las Vegas Raiders.
Trade 2 of 4
Denver acquired defensive tackle Dave Costa from Buffalo on January 23, 1967, sending the Bills a 1967 third-round pick used on Tom Rhoads and a 1968 fourth-round pick used on Edgar Chandler. Costa started all 70 games of his five Denver seasons and earned three straight AFL All-Star selections. Rhoads never played an NFL game, making Denver the decisive winner despite Chandler's useful Buffalo career.
Trade 3 of 4
Denver sent defensive tackle Dave Costa to San Diego on August 1, 1972 for running back Eddie Ray and a 1973 third-round choice used on John Wood. Ray never produced a Broncos regular-season appearance, and Wood never played for Denver. Costa, by contrast, started all 28 Chargers games across 1972 and 1973. San Diego therefore received the clearly superior realized return.
Trade 4 of 4
Buffalo Bills received Dave Costa (a) from Los Angeles/San Diego Chargers for 1975 fifth round pick (#125-Charles Waddell). The recorded outcome favors Los Angeles/San Diego Chargers.
