Walker ran, Mahomes threw, and Kansas City beat Denver 31-10 anyway

Kenneth Walker III had the kind of debut that makes you forget the offseason for a few hours. The running back carried the Chiefs' ground game for 173 yards against the Broncos, and Patrick Mahomes — nine months removed from a torn ACL and LCL — looked like himself, which is the only thing that really mattered in Week 1. A 21-point win on the road is a good day. Kansas City needed one badly after the wreckage of 2025.

The concern, as it has been all camp, is what surrounds those two. The undrafted rookie at left tackle held up well enough, but that situation remains fragile — one bad snap, one speed rusher who wins his assignment, and the whole calculus changes. The defensive injuries that showed up during the game are worth watching. Omarr Norman-Lott is already out, Ashton Gillotte's plantar fascia rupture wiped out a rotation piece before the season even started, and Chris Jones is still listed Questionable. That front can get thin in a hurry.

The road split that defined 2025 — one win in eight tries away from Arrowhead — gets its first data point here, and it's a good one. But Denver in September is a different test than a hostile environment in December. The Chiefs went 1-7 away from home last year not because of one bad game but because something broke down consistently in those settings. One win doesn't answer that. It just postpones the question.
