New York Giants–San Francisco 49ers Trade History

San Francisco acquired quarterback Arnie Galiffa from New York in August 1954 for defensive end Bob Van Doren. Galiffa appeared in four regular-season games for the 49ers without a start, completing three of 12 passes for 54 yards and throwing four interceptions. He left the NFL after that season. The return was limited, but San Francisco at least received regular-season snaps from the player it acquired.

San Francisco traded 34-year-old quarterback Y.A. Tittle to New York for second-year guard Lou Cordileone on August 18, 1961. Cordileone never approached Tittle's impact for the 49ers. Tittle instead revived his career with the Giants, throwing 96 touchdown passes in four seasons and leading New York to three consecutive NFL Championship Games. Hindsight makes the 49ers' return painfully light.

San Francisco received Bob Gaiters from New York for Aaron Thomas. Gaiters appeared in nine 49ers games in 1962, starting once, rushing 36 times for 158 yards and catching two passes for 13 yards without a touchdown. He played for Denver the following season and never returned to San Francisco. The 49ers therefore received only a brief reserve contribution while Thomas became a long-term Giants starter and Pro Bowl-caliber receiver.

New York acquired defensive back Eddie Dove from San Francisco in September 1963 for backup quarterback Ralph Guglielmi and a future draft choice that became the 49ers' 1965 third-round pick, No. 29 Bob Schweickert. Dove played 12 games for the Giants that season, intercepted two passes for 75 yards and handled punt returns for an Eastern Division champion. Guglielmi refused to report to San Francisco, and Schweickert never played a regular-season game for the 49ers.

New York acquired linebacker Ed Weisacosky from San Francisco on August 28, 1967 for a conditional draft choice that became the Giants' 1968 eighth-round pick, No. 206. Weisacosky made the Giants, appeared in all 14 regular-season games and started four. Because the condition was satisfied, San Francisco received the pick and used it on tackle Charley Brown, who never appeared in an NFL regular-season game.

San Francisco traded wide receiver Clifton McNeil to the New York Giants on May 31, 1970 for the Giants' 1971 fifth-round pick and 1972 second-round pick. The 49ers used those selections on linebacker George Wells at No. 122 and defensive back Ralph McGill at No. 28. McGill became a six-season 49ers contributor, while Wells never appeared in an NFL regular-season game.

San Francisco traded defensive tackle Roland Lakes to the Giants in July 1971 for New York's 1973 second-round selection. The 49ers used No. 41 overall on linebacker Willie Harper, who became a long-term San Francisco contributor. Turning an aging veteran into a second-round player with lasting value made this one of the clearest wins in the group.

San Francisco acquired veteran quarterback Norm Snead from New York on October 22, 1974 for the 49ers' 1975 third-round and 1976 fourth-round draft choices. Snead gave San Francisco 12 games and eight starts across the rest of 1974 and 1975, throwing for 1,705 yards with 11 touchdowns and 11 interceptions. The return was useful short-term quarterback service, though not a long-term solution.

San Francisco acquired tight end Jim O'Bradovich from the New York Giants on September 7, 1976 for the 1977 eighth-round pick at No. 211 overall. O'Bradovich played 26 games for the 49ers across 1976 and 1977.

New York Giants received Tony Dungy, Mike Hogan from San Francisco 49ers in the 1980-03-27 trade. San Francisco acquired Ray Rhodes and Jimmy Robinson. San Francisco 49ers's return was Ray Rhodes, Jimmy Robinson. New York acquired Tony Dungy and Mike Hogan. Those realized outcomes, rather than the labels on the assets alone, drive the hindsight grade.
