Kansas City Chiefs–San Francisco 49ers Trade History

Kansas City received San Francisco's 1970 third-round pick, No. 61, and used it on defensive end Billy Bob Barnett. Barnett did not develop into a comparable professional contributor, limiting the Chiefs' return from a meaningful draft slot. San Francisco, meanwhile, received immediate value from Noland Smith as an established return specialist, creating the stronger realized player outcome.

San Francisco acquired receiver Robert West from Kansas City on September 9, 1974 for the 1975 sixth-round pick that became linebacker Dave Wasick. West appeared in 10 games as a 49ers reserve that season and was later traded to Oakland for a future conditional choice that did not vest. His San Francisco impact was modest, but it still exceeded the Chiefs' return because Wasick never played an NFL regular-season game.

Kansas City sent cornerback Nate Allen to San Francisco for veteran lineman Randy Beisler and a 1976 third-round pick. Beisler's Chiefs contribution was cut short by a neck injury, but Kansas City used No. 63 on Keith Simons, who started 12 games over two Chiefs seasons. Allen played all 14 games for the 49ers in 1975 with three starts and a pick-six. The extra draft return gives Kansas City a narrow edge.

Kansas City received a 1980 ninth-round pick, correctly identified as No. 223, the selection used on Tom Tuinei. The Chiefs later moved that pick with another selection to Detroit for Larry Tearry, but Tearry was released before the 1980 regular season. The asset path therefore produced no durable on-field contribution for Kansas City.

Kansas City turned the 18th pick in the 1993 draft into Joe Montana, safety David Whitmore and San Francisco’s 1994 third-round pick. Montana immediately changed the franchise’s trajectory, leading the Chiefs to consecutive playoff appearances and the 1993 AFC Championship Game. Even at the end of his career, acquiring a Hall of Fame quarterback for one first-rounder produced exactly the short-term contention Kansas City wanted.

Kansas City acquired quarterback Steve Bono from San Francisco on May 22, 1994, for a 1995 fourth-round pick. Bono became the Chiefs' starter in 1995, made the Pro Bowl and helped produce a 13-3 season. San Francisco later used the No. 119 pick as part of its package to move up for J.J. Stokes. Kansas City received the clearer direct impact and wins the trade.

Kansas City sent two second-round picks to San Francisco for Alex Smith. Smith immediately stabilized a team coming off a two-win season, led four winning campaigns in five years, and created the bridge to Patrick Mahomes. The 49ers received meaningful draft capital, making this a good sale that was still surpassed by Smith's franchise-changing value.

Kansas City acquired wide receiver A.J. Jenkins from San Francisco on August 19, 2013 in a straight swap for Jonathan Baldwin. Jenkins appeared in all 16 games for the Chiefs in 2013 and caught eight passes for 130 yards, then added nine catches in 2014. His Kansas City production remained modest, but he gave the Chiefs considerably more game-day value than Baldwin produced for the 49ers.

Kansas City gave San Francisco No. 28 and No. 249 for Nos. 37, 105 and 178. The 49ers used the first-rounder on Joshua Garnett, who never became a durable starter. The Chiefs selected Chris Jones at No. 37, landing a franchise-defining defensive tackle, perennial Pro Bowl player and championship cornerstone. Parker Ehinger and D.J. White were secondary returns; Jones alone makes this overwhelming.

Kansas City acquired cornerback Kenneth Acker from San Francisco on August 27, 2016 for a future seventh-round pick. Acker appeared in nine games for the Chiefs in 2016 and all 16 in 2017, intercepting one pass in his second Kansas City season. He provided useful secondary depth, but the Chiefs received only two seasons before his tenure ended.

Kansas City sent Rod Streater to San Francisco in 2016 and ultimately received the 2019 seventh-round selection at No. 216, used on guard Nick Allegretti. Allegretti became an excellent late-round return, appearing in 74 games with 13 starts for Kansas City from 2019 through 2023 and contributing to three Super Bowl championship teams. The long-term line depth easily surpassed Streater's brief 49ers production.

Kansas City traded franchise-tagged edge rusher Dee Ford to San Francisco for a 2020 second-round pick, avoiding a major long-term commitment after his career-best 2018 season. The Chiefs used pick No. 63 on linebacker Willie Gay Jr., who became a multi-year starter and contributed to championship defenses. Ford helped the 49ers reach Super Bowl LIV in his first season, but persistent injuries made his five-year contract far less valuable than expected.

Kansas City moved up one spot to No. 63 and added a sixth-round choice, turning the deal into Kingsley Suamataia and Kamal Hadden. San Francisco moved back to No. 64 for Renardo Green while also adding the No. 173 pick. Green became a full-time starter, while Suamataia developed into a starting guard. Both teams found meaningful value, leaving the exchange close to even.

Kansas City sent wide receiver Skyy Moore and a 2027 seventh-round pick to San Francisco for a 2027 sixth-round pick. The future selections remain unresolved, but the 49ers already received a full season of special-teams production from Moore, including 907 kickoff-return yards and 291 punt-return yards before he moved on in 2026.
