Kenneth Walker III has 537 rushing yards in four games, but his historic Chiefs start reveals a much bigger shift in Kansas City

Kenneth Walker III has not just given Kansas City a productive running back. Through four games, he has changed what the Chiefs can ask of their offense. Walker rushed for 177 yards and two touchdowns against the Raiders, pushing his season total to 537 yards. That is the most by a Chiefs player through four games and enough to move him past DeMarco Murray for the best opening four-game rushing total in NFL history.Why has Kenneth Walker III been so important to the Chiefs?The numbers explain part of Walker’s impact, but the larger change is how much pressure he has taken off Kansas City’s passing game. He is averaging 6.2 yards per carry through four games, an extraordinary figure even before considering the volume. His 537 rushing yards have come on the back of three straight strong performances after his 173-yard, two-touchdown debut in Week 1.Walker followed that opening performance with 117 rushing yards and six catches for 61 yards against Indianapolis. He then added 70 rushing yards and scored once on the ground and once through the air against Miami. The Raiders game took things up another level.He carried 22 times for 177 yards and two touchdowns, giving Kansas City another game in which the run game could dictate how the offense operated.That matters because the Chiefs did not sign Walker merely to add another name to the backfield. His three-year, $45 million contract came with expectations, and he has quickly made the investment look justified. Kansas City is the AFC's final undefeated team, and Walker has become a major reason for that start.What does Kenneth Walker III’s record start mean for Kansas City?Walker has already moved into a part of Chiefs history usually occupied by much bigger names. His 537 yards are ahead of Marcus Allen, Priest Holmes, Larry Johnson, Jamaal Charles and Kareem Hunt through four games, according to the historical comparison cited by Men's Journal.The NFL comparison is even more striking. Walker's 537 yards have edged DeMarco Murray's 534 from 2014. Derrick Henry's 510-yard opening to 2021 ranks third, followed by Hunt's 502 and Henry's 480 in 2024.There is also a tempting projection hanging over Walker's season. His current pace would put him at 2,282 rushing yards, which would top Eric Dickerson's 2,105-yard mark from 1984. That is not a realistic expectation to place on him after only four games, but it shows how unusual this start has been.The more useful benchmark will come later. If Walker reaches 1,000 yards and keeps producing at anything close to this level, Kansas City will have far more than a hot start on its hands. It will have a running game capable of changing the shape of the offense for the rest of the season.Stay updated with the latest Asian Games 2026 news, check the Asian Games medal tally and complete Asian Games schedule.Get the latest Sports News and Live updates.
