For years, playing the Kansas City Chiefs came down to a pretty simple choice: let Patrick Mahomes beat you over the top, or drop extra defenders into coverage and dare Kansas City to run.

Defenses have made that choice again and again. Through two weeks, though, Kenneth Walker III is making the second option look a lot less comfortable.

Walker isn’t just off to a strong start. He’s already become the center of the Chiefs’ offense, leading the league in yards from scrimmage, yards after contact, and missed tackles forced. Every time Kansas City puts the ball in his hands, he’s giving the offense a chance to break a big play or simply make somebody miss.

That was clear in his Kansas City debut against the Denver Broncos. The Chiefs handed Walker the ball on each of their first four offensive plays and gave it to him seven times on the opening drive. By the end of the night, he had 23 carries for a career-high 173 yards, three catches for 18 more yards, and two touchdowns in a 31-10 win.

His biggest play came on a fourth-and-1 from Kansas City’s own 40-yard line. Andy Reid brought out a jumbo package with two extra offensive linemen and defensive tackle Khyiris Tonga, putting more than 950 extra pounds of blocking on the field. Denver knew exactly what was coming.

Walker still bounced outside and ran 60 yards for a touchdown.

That play was spectacular, but it wasn’t the most important part. The bigger takeaway was how often Kansas City trusted Walker before, during, and after that play.

The Chiefs didn’t treat their new running back like another useful piece around Mahomes. They built the game plan around him. They finished with 38 rushing attempts and 220 yards on the ground, their highest single-game total since 2020, and kept handing Walker the ball even after everybody in the stadium knew what was coming.

Two weeks in, this isn’t just a great debut or a fun early-season storyline. Walker has completely changed what the Chiefs can be on offense.

The Chiefs Finally Accepted The Invitation

The funniest part of all this is that defenses have been begging Kansas City to do exactly this for years.

When Mahomes first took over, the Chiefs could turn any patch of grass into a runway. Tyreek Hill stretched the field and Travis Kelce owned the middle.

So the league adjusted. Keep two safeties deep. Don't put as many defenders near the line. Take away the huge play and trust the Chiefs to eventually get bored or screw up a short-yardage snap before they got in the end zone.

Mahomes adapted because, well, he had to. Kansas City won two more Super Bowls after defenses changed the rules of the fight. But the offense also had to work a lot harder for their points. The Chiefs averaged 35.3 points in Mahomes’ first season as the starter. In 2023 and 2024, that number dropped to 23.2 per game.

And the run game never became the obvious counterpunch it should’ve been.

Kansas City hasn’t had a 1,000-yard rusher since Kareem Hunt led the NFL as a rookie in 2017. Isiah Pacheco came closest with 935 yards in 2023, but injuries and a loss of explosiveness changed his trajectory. Last season, an older Hunt led the team with 611 yards while averaging 3.7 per carry. Mahomes was being asked to be the leading rusher just about every week until a knee injury ended his season and Kansas City finished 6-11.

The most telling number was three. That’s how many runs of at least 20 yards the entire Chiefs offense produced in 2025.

Walker had 10 by himself.

Walker Is Built To Punish The Compromise

Walker isn’t just faster than the backs Kansas City's used lately. He changes what a normal running play can turn into.

He ran a 4.38-second 40-yard dash at 211 pounds before the 2022 draft, and you can see that speed show up in different ways. He can run through contact between the tackles, stop and restart when a defender gets there early, then hit the edge fast enough to make a good pursuit angle disappear. That’s how a fourth-and-1 against Denver turned into a touchdown instead of a two-yard gain.

And this wasn’t some random one-night breakout.

Walker broke 61 tackles for Seattle last season, fifth-most among running backs, and piled up 664 yards after contact. His 33 runs of at least 10 yards was sixth-best in the league, and his 14.9% explosive-run rate ranked third. Then he carried Seattle through the postseason, leading the NFL with 313 rushing yards and four touchdowns before running for 135 yards on 27 carries in the Super Bowl.

He became the first running back in 28 years to win Super Bowl MVP. A month later, Kansas City gave him a three-year deal and the keys to the offense.

They’ve adjusted the structure around him, too. Seattle ran 52.6% of their snaps from under center last season. Kansas City operated from shotgun 80% of the time. Walker's always looked most comfortable taking the ball downhill, reading the blocking, and making one hard cut. Through two games, Walker's been handed the ball from under center 24 times.

Reid hasn’t scrapped his offense. He’s just meeting Walker halfway. Kansas City mixed those downhill looks with shotgun runs and heavy personnel.

That trust matters in short yardage. It matters even more when a defense tries to stay light.

Week 2 Showed What This Can Become

One huge game can fool you a little.

Denver missed 28 tackles against Kansas City, and Walker was responsible for half of them. That says something good about him, but it also says something pretty bad about the Broncos’ defense. Nobody should expect that kind of breakdown every Sunday.

Then came the Indianapolis game.

Walker didn’t rip off another 60-yard run. He did something that might matter even more for this argument: He kept the offense on schedule. He carried it 24 times for 117 yards, caught six passes for 61 yards, and finished with 178 yards from scrimmage in Kansas City’s 33-30 overtime win.

And when the Chiefs needed one last answer, Walker gave them one. With the score tied in overtime, he caught a quick pass on third down and fought through traffic for 22 yards to put Harrison Butker in range for the winning kick.

Through two games, Walker has 290 rushing yards and 369 yards from scrimmage, leading the NFL in both categories. He’s forced 26 missed tackles and gained 189 rushing yards after contact.

But the most exciting number from Week 2 belonged to Mahomes.

He threw for 382 yards and three touchdowns, his biggest passing game since 2023. He completed a career-high 14 passes off play action, picking up 137 yards and two touchdowns on those plays. It was Kansas City's first game with at least 350 through the air and 150 on the ground since 2018.

That’s the whole idea coming together in real time.

Indianapolis couldn’t sell out to stop Walker because Mahomes was waiting behind him. They couldn’t sit comfortably in coverage because Walker had just made a much better Denver defense pay for trying to play that way. The Colts had to respect both threats, and suddenly those passing windows looked a little bigger. Kelce caught nine passes for 101 yards. Tyquan Thornton came up with two huge plays downfield. The play-action game finally had some real action behind it.

That’s what changed. Walker doesn’t have to run for 173 yards every week. He just has to make everyone believe he can.

The Point Isn’t To Take The Ball Away From Mahomes

Nobody needs to turn the best quarterback alive into a handoff specialist.

The point of a real running game isn’t to take the ball out of Mahomes’ hands. It’s to make every choice the defense makes feel wrong.

Leave six defenders in the box and Walker gets room to work. Bring a safety down and Mahomes gets the coverage look he wanted. Start attacking downhill and Reid can answer with play action, screens, or all the motion he’s spent a decade using to make linebackers dizzy.

Walker can be part of those passing answers, too. He has nine catches for 79 yards and a touchdown through two games — and 76 of those yards came after contact. His 18.9% target share is well above his previous career high of 14.1%, and his 22-yard catch in overtime showed why Kansas City wants him out there for more than handoffs.

There’s also the less glamorous benefit: a functional running game creates second-and-5 instead of second-and-10. It shortens drives for the defense and gives a 31-year-old quarterback coming back from a major knee injury less snaps where he has to rescue everybody.

Kansas City spent the last few seasons proving they could survive without that luxury. But surviving isn’t the same as making life easy. There’s no reason to keep volunteering for hard mode.

Two Games Still Isn't A Full Transformation

There are fair reasons to pump the brakes.

Walker’s 6.2 yards per carry won't last forever. Denver’s tackling was rough, and Indianapolis had just let Derrick Henry run for 144 yards and three touchdowns the week before. The Chiefs have also already given Walker 47 carries and 13 targets. His career high is 228 carries, and in just three seasons he's already missed 10 games.

That kind of workload's worth watching. So is Walker’s habit of occasionally bouncing a run outside when the boring four yards were sitting right there. The same instinct that turns into a 60-yard touchdown can also turn into a two-yard loss against a faster defense.

But none of that changes the bigger point.

The shift isn’t that Kansas City is suddenly going to run the ball 38 times every week. It’s that defenses can’t treat the handoff like the second option anymore. The Chiefs paid for a real lead back and then showed they were willing to keep feeding him.

For years, defenses could build their entire plan around making Kansas City win without the big play from out of the backfield. Walker's already shown he can create one without Mahomes even having to throw the ball.

That doesn’t replace the Chiefs’ offense. It gives them another way to hurt you.

The Chiefs play the Dolphins on Sunday at 1 p.m. on CBS, with the game also streaming on Paramount+.
