Kenneth Walker III is a transitive player for Chiefs and fantasy football managers lucky enough to draft him

When you're making predictions about the NFL season - much less when you create fantasy content and you essentially must have a take on every offensive player in the league - you're going to get a lot of things wrong. I already regret a good handful of offseason calls after just one week's worth of data.

One prediction I am already prepared to take to the bank is that Kenneth Walker III would be a fundamental change force and a transformative figure for the Kansas City Chiefs.

Chiefs' run game had been punchless

We've all participated in plenty of discourse around the Chiefs' withering passing game over the previous two seasons and noted concerns in the wide receiver room ever since Tyreek Hill was traded. Trust me, I've been at the forefront of that conversation. Yet, it was never the biggest problem for the team's offense. That honor fell to the NFL's least intimidating run game

To put into context how this was clearly a backfield issue, the Chiefs had the fourth-lowest stuff rate (runs of zero or negative yards) and the 13th-highest success rate on running back runs in this same span. Essentially, they had the makings of an environment for a viable run game overall but while they didn't lose ground, the runners just offered zero juice.

Walker's electric start to season

Enter Walker, who absolutely exploded in his debut against the Chiefs on Monday Night Football. He was the fastest and best overall player on the field.

Kenneth Walker reached 21.21 MPH on his long TD run on MNF.

That one carry is already 50% of the amount of 20+ MPH plays that the Chiefs skill players had as ball carriers in all of 2025, per @NextGenStats.

Walker's 191 yards from scrimmage were the most of his NFL career. His previous best mark was back in October 2022 with 167. It was the best regular-season fantasy performance with 32.6 half-PPR points, although his performance against the 49ers in the Divisional Round of last season's playoffs topped it at 34.0.

Now with his new team, Walker picked up right where he left off in the Super Bowl for his former club, operating as a featured back while handling 72% of the running back touches - 88% in the first three quarters - and winning as a relentless tackle-breaker.

What's more notable is how much Walker did indeed change the way the Chiefs operated on offense. They were one of the scoring units that looked the most different when compared to their 2025 versions.

The Chiefs ranked 30th in under-center rate in 2025 but jumped to 17th in Week 1. They were a heavy zone-run scheme but used a ton of power and gap in the opening week of the season. Walker was immediately the most productive back they've had out of under center runs in years.

The Chiefs also jumped to 14th in motion rate and 17th in play-action rate, per Fantasy Points Data, after being a bottom-dweller in both metrics last season. You saw them in even heavier, condensed sets after being a spread-and-shred team for much of the last five to six seasons, at least.

I was skeptical of bringing back Eric Bieniemy as offensive coordinator, because I believed this team needed to get out of its own echo chamber of offensive coaches, and I was critical of his work as the primary offensive architect with the 2023 Washington Commanders. Yet it's clear that Bieniemy, during his time away from the Andy Reid nest, has picked up some of the schematic twists other coaches are leaning into across the NFL. The Bears offense, where he was the running backs coach last year, was a heavy-personnel, under-center run game but with more zone-based principles. Bienemy deserves a huge shoutout for leaning into this offense and is no doubt a huge reason Walker is in town as the featured player.

Walker altering Chiefs' offensive identity

Bottom line: The Chiefs offense we saw on Monday night was fundamentally different than anything we've seen from this franchise in the Patrick Mahomes era. Not only is Walker the prime beneficiary ... he's the variable that makes it so; the straw that stirs the drink.

I foresee no reason this should change going forward. The Chiefs reminded us again on Monday that they simply don't have the receiving personnel to be a pass-leaning team right now. They'll look to the ground game to find layups and explosive plays. Walker is also a factor in the passing game, drawing six targets while running a route on 46% of Mahomes' dropbacks. He's more dangerous with the ball in his hands than the current version of Rashee Rice, fresh off having to rehab from knee surgery while serving jail time, in the screen game.

The Chiefs defense is also a rebuilt unit that turned the Broncos into the worst offense in Week 1. That development will keep Walker in game scripts that lean into the run. As I wrote in The Yahoo Fantasy Ultra Draft Kit this summer, I believe the 2026 Chiefs intend to be a defense-first team with a rock-fight offense built on the run game. Walker is the leading actor in that story.

Walker's sky-high fantasy potential

If we were redrafting today, I can't see more than four or five running backs I'd even consider taking ahead of Kenneth Walker III. He was my 12th overall player at the end of fantasy draft season. I'd likely push that up a few more spots. Jahmyr Gibbs and Bijan Robinson are the two names that for sure still project better than Walker. Jonathan Taylor was a monster in Week 1 and played 89% of the team's snaps. The conversation starts here, with the only other name tempting me at running back being Derrick Henry, who was my 14th overall player in draft ranks.

How many wideouts are you ranking ahead of Walker right now? It can't be many. Every single data point from Week 1, which is merely a continuation on the trail of the breadcrumbs laid by the offseason clues, is pointing sky-high for this talented and transformative running back.

The one thing that could derail high hopes

Now, in this final stanza, we should note the one thing that could stop this train in its tracks. No one wants negativity in this moment but it's worth noting. By all accounts, the Seahawks didn't want to overwork Walker in 2025 and make him a featured player because he is a guy who has struggled with injuries throughout his career. It frustrated fantasy managers, and those folks surely feel vindicated after he was the featured back in the playoffs and even more so in Week 1, but it did work out for Seattle in the end. They won a Super Bowl on the back of a fresh and explosive Walker in the postseason run.

Walker registered 29 opportunities in Week 1. He had 31 in the Super Bowl earlier this year but otherwise, you have to go back several seasons to see him consistently reaching these heights in the regular season. Walker has 13 regular-season games with 22 or more touches on his resume. Nine of them came between 2022 and 2023.

Can he stay healthy and hold up to the workload? That's the only question I have about his rest-of-season outlook. If he can, Kenneth Walker III will without a doubt go down as one of the best players to roster in 2026 fantasy football.
