It’s been a rough few months for the Kansas City Chiefs.The 6-11 Chiefs missed the playoffs for the first time in head coach Andy Reid’s 13-year tenure this season, while serious question marks hang over the team’s two biggest weapons.Reid could lose members of his coaching staff as he comes off his first losing season in KCGettyThree-time Super Bowl MVP Patrick Mahomes suffered a torn ACL in December while tight end Travis Kelce’s retirement decision remains up in the air.Not only that, but the Chiefs’ coaching staff is in a state of flux amid firings and personnel seeking new challenges.Matt Nagy, who has served as Kansas City’s offensive coordinator since 2023, is no longer under contract and is interviewing for head-coaching openings.On Wednesday, NFL insider Jordan Schultz reported that Nagy already has interviews lined up with three teams: The Tennessee Titans, Las Vegas Raiders and Arizona Cardinals.KC has also lost assistant defensive line coach Alex Whittingham to the University of Michigan, and they fired wide receivers coach Connor Embree this week.And now, a day after defensive coordinator Steve Spagnuolo interviewed for the vacant head-coach role with the Titans, another of Andy Reid’s assistants has interviewed for a new role.According to reports, Joe Cullen, the Chiefs’ defensive line coach, interviewed for the Washington Commanders vacant defensive coordinator position after the team fired Joe Whitt Jr. earlier this week.Commanders head coach Dan Quinn is searching for a DC, and according to a report by Mike Garafolo, Cullen is a leading candidate.“The Commanders have interviewed Chiefs DL coach Joe Cullen for their vacant defensive coordinator job, source said. He is a long-time D-line guru and was previously the Jaguars DC.”Cullen, 58, entered the NFL as a defensive assistant in 2006 with the Detroit Lions. Cullen is highly thought of and reportedly wanted by the Washington CommandersGettyChiefs DC Steve Spagnuolo could also leave for a vacant head coach positionGettyGeorge Karlaftis (right) and Chris Jones (left) have flourished under Cullen’s tutelageGettyHe also was the defensive line coach for the Cleveland Browns, Tampa Bay Buccaneers, and Baltimore Ravens before joining Jacksonville as the Jaguars’ defensive coordinator in 2021.Cullen joined Spagnuolo and the Chiefs in 2022, helping the team win three Super Bowls while establishing himself as one of the league’s best defensive-front specialists.He’s responsible for coaching up the likes of George Karlaftis and Chris Jones, with Jones in particular flourishing under Cullen’s watch.The All-Pro posted 26 combined sacks in his first two seasons under Cullen and led the team with seven sacks in 2025.Jones, widely regarded as one of the NFL’s leading defensive tackles, shared his thoughts after the news that Cullen had spoken with Washington dropped.“Oh sh!+…….” Jones posted on X.It was obvious that changes were coming after the Chiefs’ disastrous season.While Reid is staying put, Kansas City clearly feels like cleaning house with their coaching staff puts them in a better position for 2026 beyond.Major changes are clearly already underway, with KC expected to look at bringing in several new assistants and coaches over the coming weeks.Stay up to date with the latest from the NFL across all platforms – follow our dedicated talkSPORT USA Facebook page and subscribe to our talkSPORT USA YouTube channel for all the news, exclusives, interviews and more
