GettySean Payton and the Denver Broncos will clash with the Kansas City Chiefs in the regular-season opener. One of the two teams’ offseason coaching decisions is expected to swing the AFC West in 2026.Both teams will have new offensive coordinators, though the Chiefs are enjoying a reunion.There are far more unknowns about the Broncos’ switch, despite their new OC spending the past three seasons.Ex-NFL Scout Warns Broncos, AFC West About ChiefsGettyEric Beienmy is back with the Kansas City Chiefs for the 2026 season.Payton and the Broncos could face a vintage version of the Chiefs. They are expected to have quarterback Patrick Mahomes under center come Week 1. That is despite his tearing his ACL late last season.And yet, it is not Mahomes’ return to health. Instead, OC Eric Bienemy’s return could be the difference-maker. He is coming off a one-year stint as the Chicago Bears’ running back coach.Former NFL scout Bucky Brooks picked it as the “offseason move that could tilt” the division.“The offense has lacked consistency, discipline and attention to detail without its former coordinator. Kansas City fielded the league’s top scoring attack during Bieniemy’s last season with the team in 2022; over the past three campaigns, the Chiefs have finished 15th, 15th and 21st. Bieniemy’s ‘tough love’ approach clearly resonated with many players in K.C., leading to better performance and production from the unit,” Brooks wrote on July 26.“The former NFL running back’s experience and expertise with the ground game helped Reid maintain a more balanced play-calling style, instead of relying too heavily on Patrick Mahomes’ magical playmaking skills. And seeing how Mahomes is coming back from a torn ACL/LCL, it’s wise to give him as much support as possible. Given the significant decline in the offense’s production without Bieniemy on the sideline, the return of the veteran assistant could help the Chiefs bounce back from a 6-11 season.”The Broncos swept the Chiefs last season, including a 22-19 victory over Mahomes’ crew in Week 11. Still, the Chiefs are exponentially better with the two-time MVP, Mahomes, under center than not.Broncos OC Davis Webb Lands on WatchlistGettyDavis Webb is tasked with helping Bo Nix and the Denver Broncos’ offense reach a new level in 2026.The Broncos hope Davis Webb taking over of the play-calling duties from Payton will elevate quarterback Bo Nix and the offense. The unit finished 10th overall but was 14th in scoring last season. Webb landed on The Athletic’s list of assistants “who could break out.”“At the NFL Scouting Combine in February, league people said Webb is
