Kenneth Walker’s 173-Yard Debut Tests Two Old Patterns

Kenneth Walker III ran for a career-high 173 yards and scored twice in his Kansas City Chiefs debut, a 31-10 win over the Denver Broncos on Monday night at Arrowhead Stadium. On 23 carries and three catches he piled up 191 yards from scrimmage, more than Denver’s entire offense (176 yards), against a front that allowed the second-fewest rushing yards in the league in 2025.

Kansas City has opened a century with two other 100-yard running-back debuts, from Kareem Hunt in 2017 and Clyde Edwards-Helaire in 2020, and neither man held the job for long. Walker’s night was bigger than both, and it came from a reigning Super Bowl MVP on a three-year, $43.05 million deal. Those are the two patterns the tape now has to beat.

A Career High Against Last Year’s No. 2 Run Defense

Denver allowed 1,548 rushing yards all last season, behind only Jacksonville’s 1,455, and had not given up this many on the ground since the New York Jets piled up 234 in Week 5 of 2023. Walker still averaged 7.5 yards a carry, forced 14 missed tackles, and turned a fourth-and-1 bounce in the third quarter into a 60-yard touchdown that made it 21-7.

“I knew they were going to crash in, so when they crashed in, I just bounced it out. I was one-on-one with the corner, I outran him and it was off to the races from there,” Walker said. Next Gen Stats clocked him at 21.21 mph on that run, the third-fastest carry of his career. Strip out the long score and he still averaged 5.1 yards on the other 22 rushes.

I told you all, literally, like first press conference. Y’all were asking, what’s the difference with our offense? And I said, K9. Like, it’s just that simple.

Patrick Mahomes, quarterback, after the Broncos game

Kansas City handed him the first four plays, a 32-yard opening drive that Mahomes finished with a 15-yard rushing score, the first of his 23 yards on seven carries in his return from a torn ACL and LCL suffered on Dec. 14. Walker had 14 carries for 89 yards by halftime, when the Chiefs led 14-7 after a 13-yard touchdown catch by Rashee Rice. A 2-yard shovel pass 21 seconds into the fourth quarter, Walker’s second score, made it 31-10.

HOW THE POINTS LANDED

1. First quarter: Mahomes’ 15-yard run puts Kansas City up 7-0, and the Chiefs never trail.
2. Late first half: Rice’s 13-yard catch makes it 14-7 at the break.
3. 12:43, third quarter: Walker’s 60-yard run on fourth-and-1 pushes the lead to 21-7. He already had 149 rushing yards.
4. 21 seconds into the fourth: Mahomes’ shovel to Walker from 2 yards out closes the scoring at 31-10.

The Chiefs finished with 220 rushing yards, their most since 245 against Buffalo in Week 6 of 2020, and 392 total yards to Denver’s 176. Bo Nix’s offense managed nine first downs and converted 2 of 12 third downs. Andy Reid called Walker’s night spectacular and said the plan was not a pre-set carry count. “It means a lot. It means they trust me. It’s good to feel that way,” Walker said of the 26 touches, which included six targets. He played 46 of 67 snaps (69 percent) before rookie Emmett Johnson (8 carries, 24 yards; 2 catches, 44 yards) closed it out.

Hunt Opened With 148, Edwards-Helaire With 138

Walker is the third Chiefs player since 2000 to run for at least 100 yards in a team debut, and he blew past the other two on fewer carries than Edwards-Helaire needed. Hunt did it as a third-round rookie at New England on Sept. 7, 2017. Edwards-Helaire did it as a first-round pick against Houston on Sept. 10, 2020. Walker did it as a 25-year-old Super Bowl MVP who had already posted two 1,000-yard seasons in Seattle.

THE THREE 100-YARD CHIEFS DEBUTS SINCE 2000

Hunt turned that 148-yard night into Hunt’s 1,327-yard rookie season on 272 carries, the last 1,000-yard rushing year any Chief has posted and the last one before Patrick Mahomes became the starter. He was gone by November 2018. He came back in 2024 and 2025 as a short-yardage veteran and led Kansas City last year with 611 yards on 163 carries. The only time a Chiefs back even reached 60 rushing yards in a 2025 game was Hunt’s 104 against Indianapolis.

Edwards-Helaire’s 138 yards were the start of 803 yards in 13 games as a rookie. He never had another 1,000-yard season, finished with four 100-yard games, and was a bit player by 2025. Walker’s 173 yards are also the most by any player in a game Mahomes has started, and the most by a Chief since Jamaal Charles ran for 226 against Indianapolis in 2012, the year before Reid arrived.

Three Super Bowl MVPs Changed Teams and Flopped

Walker is the fourth player to leave in free agency the spring after winning Super Bowl MVP, and the first running back in that group. The prior three cashed bigger deals than they had been playing on and were gone from those new teams within two years.

THE THREE WHO LEFT AFTER THE TROPHY

• Larry Brown, 1996: The Cowboys corner, MVP of Super Bowl XXX on two interceptions, signed a five-year, $12.5 million deal with the Raiders, started one game, had one interception, and was released in 1998.
• Desmond Howard, 1997: The Packers returner, MVP of Super Bowl XXXI, signed a four-year, $6 million deal with the same Raiders, lasted two seasons, and was waived after 1998 before a short return to Green Bay.
• Dexter Jackson, 2003: The Buccaneers safety, MVP of Super Bowl XXXVII on two picks, signed a five-year, $14 million deal with the Cardinals, had a career-high six interceptions in 2003, then was released in October 2004 after a back injury.

Walker’s case is different in one hard way. Brown, Howard and Jackson were role players who peaked on a single January night. Walker had already run for 3,555 yards and 29 rushing touchdowns in four Seattle seasons before he took the Arrowhead handoffs, and he was the first running back named Super Bowl MVP since Terrell Davis in Super Bowl XXXII. A 173-yard Week 1 does not yet put him next to Davis. It does put him ahead of Brown, Howard and Jackson after one game.

Why the Seahawks Let Walker Walk

Seattle won Super Bowl LX on Feb. 8 at Levi’s Stadium, 29-13 over New England, and Walker was the clear engine: 27 carries, 135 rushing yards, 161 yards from scrimmage. He had 1,309 yards from scrimmage in the 2025 regular season, including 1,027 rushing yards last season on 221 carries, then added 417 scrimmage yards and four touchdowns in three playoff games. The Seahawks still let the four-year rookie contract expire.

Kansas City agreed to terms on March 9 and signed him March 12, a three-year pact worth $43.05 million on the base, $28.7 million guaranteed, and up to $45 million with extras, about $14.3 million a year. Seattle had already committed more than $600 million in contract value to keep other core players and later spent a 2026 first-round pick on running back Jadarian Price. Walker was not tagged and was not traded. His deal ran out, and the Chiefs, coming off a 6-11 year that snapped a 10-season playoff run, paid him.

Isiah Pacheco, Kansas City’s starter for most of the past two seasons, signed a one-year, $1.8 million deal with Detroit and had back surgery Monday that is expected to cost him 12 weeks. Hunt is gone from the 2026 depth chart. The backfield behind Walker on Monday was Johnson, a fifth-round rookie, and Brashard Smith, a gadget back. Reid now has the lead runner the Mahomes years never kept.

Fifteen Completions Still Produced 31 Points

Mahomes wore a brace on the repaired left knee and completed 15 of 27 passes for 184 yards, two touchdowns and one interception, with two sacks and an 86.0 passer rating. Brandon Jones picked him off in Chiefs territory, and the passing game was slow to click, which is the night Kansas City paid Walker to cover.

The Chiefs ran 67 plays and dropped back 32 times. They opened in 11 personnel on 49 percent of snaps, 12 personnel on 30 percent, and used extra linemen on 7 percent, with undrafted rookie Kahlil Benson starting at left tackle. Mahomes said the line took Denver’s front as a challenge and set the tone even when the pass game lagged. He added, after the game, that the line and K9 took the night over.

That is the practical use of a 220-yard ground game in Week 1 of a quarterback’s return from two torn ligaments. Kansas City scored 31 points without asking Mahomes to throw 40 times. Travis Kelce’s 59-yard catch set up a Harrison Butker field goal, and the defense stripped Nix, but the offense’s shape was Walker on first down, Walker on third-and-1 (he converted three of those in the first half), and Walker on fourth-and-1.

The 60-Yard Run Kansas City Had Not Seen Since 2019

The Chiefs have not had a 1,000-yard rusher in any of Mahomes’ seasons as the starter. Last year’s club ranked 25th in the NFL with 1,812 rushing yards, and over the past two seasons the longest run by anyone in red was 35 yards by wide receiver Xavier Worthy. Walker’s 60-yard score was the longest Kansas City run since Damien Williams’ touchdown bursts of 91 and 84 yards in 2019.

WHAT THE TRACKING SAID

• Yards over expected: Walker produced 101 rushing yards over expected, a Next Gen Stats gap that measures what the blocking and defense should have allowed versus what he actually gained.
• Missed tackles: He forced 14 for the game and nine in the first half, the most by a Chiefs running back in a full game since 2021.
• First downs: Eight of his 23 carries picked up a first down, a 34.8 percent clip, and he converted four short-yardage tries including the long touchdown.
• Speed: 21.21 mph on the 60-yarder, with the kind of outside burst Kansas City’s backs did not have last year, when Hunt and Pacheco combined for minus-39 rushing yards over expected.

Those tracking numbers sit on how expected rushing yards are calculated from the location and speed of blockers and defenders at the handoff. They are also one game. Denver’s missed-tackle rate on Monday was among the worst single-game marks since 2018, and the Broncos will host Jacksonville next. Kansas City hosts the Indianapolis Colts on Sunday night at 8:20 p.m. ET, a defense Derrick Henry already gashed in Week 1.

Hunt’s 148-yard debut became a rushing title. Edwards-Helaire’s 138-yard debut became a timeshare. Walker’s 173-yard debut is the loudest of the three, and it still has 16 games to prove it is the first one that stuck.

Frequently Asked Questions

What Were Kenneth Walker’s Stats in Super Bowl LX?

Walker carried 27 times for 135 yards and finished with 161 yards from scrimmage in Seattle’s 29-13 win over New England on Feb. 8, 2026, at Levi’s Stadium, the most rushing yards in a Super Bowl since Terrell Davis’s 157 in Super Bowl XXXII, and he did it without scoring a touchdown, a first for a running back named Super Bowl MVP.

Who Had the Biggest Veteran Rushing Debut With a New NFL Team?

Michael Turner ran for 220 yards in his 2008 debut with the Atlanta Falcons, the only veteran moving to a new club who has topped Walker’s 173 in a first game, according to NFL Research; Walker’s total is the second-highest in that group.

How Many Rushing Yards Did the Chiefs Have in 2025?

Kansas City ran for 1,812 yards last season, 25th in the NFL, with Hunt (611 yards) leading the club after he signed off the street in Week 2, which is the production the $43.05 million Walker deal was signed to replace.

What Does Rushing Yards Over Expected Measure?

It subtracts the yards a ball carrier is projected to gain, based on the position, speed and direction of blockers and defenders at the handoff, from the yards he actually gained, so Walker’s +101 on Monday means he produced about 101 more rushing yards than the look at the snap said he should have.
