Patrick Mahomes, Chiefs Dealt Coaching News on Thursday

After missing the playoffs, the Chiefs have undergone several changes to Andy Reid’s coaching staff. Multiple assistants have departed for other NFL opportunities, while offensive coordinator Matt Nagy left to join the New York Giants. Kansas City replaced Nagy with former offensive coordinator Eric Bieniemy, though the Chiefs could still be at risk of losing another coach.

Dan Williams joined the Chiefs in 2019 as a coaching intern before being promoted to assistant to the head coach the following year. In 2023, he became Kansas City’s assistant quarterbacks coach, a role he has held for the past three seasons while working under quarterbacks coach David Girardi. During that span, Williams has worked closely with Mahomes while helping the Chiefs win three Super Bowls in five appearances.

But on Thursday, NFL Network’s Cameron Wolfe reported that the Arizona Cardinals have requested permission to interview Williams for their vacant quarterbacks coach position. Because the move would be a promotion, the Chiefs cannot block the interview, and if Williams were to leave, Mahomes could be working with a new assistant quarterbacks coach next season.

"Arizona Cardinals have requested to interview Dan Williams for their QB coach position, per source," Wolfe wrote on X. "Williams is in Year 7 with Chiefs, last 3 as assistant QB coach. A young rising coach and key figure for Patrick Mahomes with a chance for elevation."

While the Chiefs continue to address Reid's coaching staff, they will also look to make changes to the roster when free agency begins on March 11. Then, they will have the No. 9 pick in the 2026 NFL Draft, which starts on April 23.
