Revamped defense plus Kenneth Walker III: How the Chiefs re-established themselves as a Super Bowl contender

The Kansas City Chiefs are rapidly reclaiming their Super Bowl relevance after a rare playoff miss last season, thanks to a dual-pronged offensive and defensive transformation. Kenneth Walker III, acquired as a high-profile free agent, is leading the NFL in rushing yards (537) through four games, easing the workload on quarterback Patrick Mahomes in a league trending toward run-heavy offenses.

Meanwhile, defensive coordinator Steve Spagnuolo has reshaped the unit with a new roster, featuring a rookie defensive class that has already elevated the team’s pass-rush efficiency. Kansas City is on pace for its highest pressure rate in a decade, with 35% of defensive snaps filled by players not on last year’s roster—a strategic overhaul that has improved their defensive expected points added (EPA) per play to a mark last seen during their 2024 Super Bowl-winning season.

Though the defense has struggled to convert pressures into sacks (just four on the year), the reduced reliance on excessive blitzing has allowed the secondary to step up, reinforcing the Chiefs’ return to AFC elite status.
