The Kansas City Chiefs continue to reveal more about the new staff being built around offensive coordinator Eric Bieniemy. Sam McDowell of the Kansas City Star reported the initial departures of four assistant
coaches last week, then added two more to the list on Tuesday evening.
Assistant running backs coach Mark DeLeone and offensive assistant Kevin Saxton will not return to the Chiefs’ staff in 2026, confirmed by McDowell. With these two vacanies added, there will be at least five new faces among Kansas City’s offensive coaches next season: Bieniemy, wide receivers coach Chad O’Shea, and the eventual hire to coach the running back position.
Before joining the Chiefs for 2025, DeLeone was a defensive assistant coach for every NFL job he held, including the quality control job he held for the first three seasons of head coach Andy Reid’s tenure in Kansas City. He earned the right to be a position coach in 2018 and led the inside linebackers for the final season of defensive coordinator Bob Sutton’s time here.
The switch to offense only lasted one year in Kansas City for DeLeone, while Saxton will leave the organization after spending three seasons on staff.
