Chiefs stay perfect at 5-0, beat Chargers behind Kenneth Walker's two touchdowns

The Kansas City Chiefs beat the Los Angeles Chargers 22-6 on Sunday at Arrowhead Stadium, improving to 5-0 and remaining the only unbeaten team left in the AFC. Running back Kenneth Walker III carried the offense with 128 yards and two touchdowns on 19 carries, while the Chiefs defense held Los Angeles out of the end zone for the entire game.

Quarterback Patrick Mahomes also passed a personal milestone: the win was his 100th as a regular-season starter, coming in his 131st start, which ties Tom Brady for the fewest starts needed to reach 100 career wins, according to the Chiefs' own recap of the game.

The numbers

Kansas City scored all of its points in the first half: a field goal on the opening drive, a 33-yard Walker touchdown run on the Chiefs' second possession, a Chargers field goal to make it 10-3, and then two more Kansas City scores in under two minutes before halftime — a 2-yard Walker touchdown and a 50-yard field goal from Harrison Butker. The Chiefs did not score again, relying on their defense to close out the second half.

Los Angeles managed just 259 total yards on 63 plays and never found the end zone. Kansas City's defense forced two takeaways — an interception by Jack Cochrane and a fumble forced by L'Jarius Sneed and recovered by Drue Tranquill — and sacked Justin Herbert four times after recording none in the three games prior, according to the team's detailed statistical breakdown of the win. Linebacker Nick Bolton's 11 tackles were the 26th double-digit tackle game of his career, a new franchise record.

How we got here

The Chargers arrived at Arrowhead at 0-5, a start that had already been billed before kickoff as one of the more daunting trips of the season for a winless team, according to an Associated Press preview of the matchup. They were also banged up. Starting left tackle Joe Alt, star safety Derwin James and cornerback Donte Jackson were all ruled out with injuries, along with backup lineman Kayode Awosika and receiver Tre' Harris, according to the Chargers' own injury report released before the game. Herbert finished 22-of-37 for 204 yards against a defense missing few starters of its own, aside from offensive tackle Jaylon Moore, who left early with a concussion.

Walker's performance extended a historic start to his Chiefs tenure. Kansas City signed the 25-year-old, a Super Bowl MVP, to a three-year free-agent contract in March, and he has rewarded the move by leading the NFL in rushing yards, yards per game and runs of 20 or more yards through five weeks. He is now one of just four players since at least 1958 to rush for 660-plus yards and six or more touchdowns through a team's first five games, a group that includes Jim Brown, O.J. Simpson and Terrell Davis.

"He's a stud," Chiefs coach Andy Reid said of Walker after the game, praising his vision and toughness. On the win itself, Reid said the team had to "battle through" an ugly, low-scoring game, calling victories in the NFL "hard" to come by regardless of the score.

Who is affected

Kansas City is now one of just three remaining undefeated teams in the NFL, a status that, combined with the team's recent history of slow starts followed by deep playoff runs, has done little to quiet talk of a fourth Super Bowl appearance in six years for the Mahomes-Reid era. The result keeps Kansas City alone atop the AFC standings and extends its dominance of its own division: the Chiefs are 3-0 against AFC West opponents this season and have gone 39-12 against the division since 2018, the best mark in the league over that span. For the Chargers, the loss drops them to 0-6, their worst start in franchise history, and raises pressure on first-year head coach Jim Harbaugh's staff heading into the back half of the season.

Linebacker Nick Bolton, whose unit has struggled for consistency in the pass rush this season, pointed to the four-sack game as evidence the pressure had been building even when it was not showing up in the box score.

"All year, we've been generating pressure, we just haven't found a way to get the job done," Bolton said.

Mahomes, who threw for 272 yards and was not intercepted, leaned more on the ground game than his arm for much of the afternoon, especially after Kansas City lost two of its top three wide receivers to injury earlier this season. Rookie Xavier Worthy set season highs with seven catches for 73 yards, and Andrew Armstrong, elevated from the practice squad for the game, caught his first career regular-season pass. Edge rusher George Karlaftis, who recorded one of the Chiefs' four sacks, now leads the NFL in quarterback pressures since Week 4, with 19, as Kansas City pressured Herbert on 17 of his 44 dropbacks.

What happens next

Kansas City will have extra time to prepare for its next test: a Sunday night road game against the Seattle Seahawks, a measuring-stick matchup against another playoff-caliber team. The Chiefs and Mahomes-Reid pairing's 5-0 start is now the third time the duo has opened a season unbeaten through five games, a distinction shared with only three other coach-quarterback pairs in NFL history, including Bill Belichick and Brady.

Los Angeles, meanwhile, returns home still searching for its first win of the season, with its injury list offering little hope of an immediate turnaround. Quarterback Justin Herbert has now posted the lowest passer rating of any starting quarterback in the league through six weeks, a number the Chargers will need to see improve quickly if the season is to avoid becoming a lost one.
