When the NFL scrapped its Monday Night doubleheader format for 2026, we assumed some marquee darling would inherit the league’s full attention in Week 1: a Super Bowl rematch, a rookie quarterback’s debut, something built for a highlight reel. Instead, the whole night belongs to a team that finished 6-11 last year and missed the playoffs. We figured that was a gift to the Chiefs. It might be the opposite.
Denver Broncos at Kansas City Chiefs, Monday, Sept. 14, 8:15 p.m. ET, Arrowhead Stadium: the only game on the only night, with Joe Buck and Troy Aikman calling it for ESPN/ABC and Peyton and Eli Manning simulcasting next door. The league didn’t design this concentration of attention as a favor to either franchise. Scrapping the doubleheader was an overhaul of how the whole 2026 schedule works, not a spotlight built around one rivalry. Schedule quirks still land on somebody, though, and this one lands on a Chiefs team with nowhere left to hide from what happened to it last season.
Why the NFL Gave Week 1’s Only Spotlight to This Game
There’s a real rivalry underneath the scheduling quirk, which is more than you can say for most nationally inflated games. Kansas City and Denver have combined to win every AFC West division title going back to 2010, with Kansas City holding the division for nine consecutive years before the Broncos took it back in 2025 at 13-3, their first title since 2015. That’s two teams with legitimate recent championship pedigree meeting in Week 1, which doesn’t happen often on its own merits.
(Networks don’t clear an entire night for a team unless they think something about it is genuinely unresolved.)
Pedigree isn’t why the whole league is watching Monday, though. It’s watching because the team hosting the game just lived through the worst season of the Patrick Mahomes era, and nobody outside the building knows yet whether that was a one-year accident or the start of something longer.
What Actually Broke Last Season
The Chiefs opened 5-3, well within their normal range under Andy Reid. Then it came apart: a 1-8 finish, a six-game losing streak to close the year, a 1-9 record in one-possession games, and a 1-7 mark on the road.
(A team that finishes 1-9 in one-score games didn’t run out of luck; it ran out of whatever used to make it good in exactly those moments.)
The inflection point was Week 15 against the Chargers, the same game that eliminated Kansas City from playoff contention. Mahomes tore his ACL and LCL late in that game, ending his season on the spot. Backup Gardner Minshew got hurt the following week, which pushed third-stringer Chris Oladokun into the final two starts of the season. Denver swept the season series. Kansas City finished third in the division at 6-11, missing the playoffs for the first time since 2014, snapping a 10-year postseason streak — the second-longest in NFL history, and the longest active streak in the league before it ended — and closing out a run of ten straight 10-win seasons that ranks third all-time.
Is 2026 Really Travis Kelce’s Last Season?
Kelce hasn’t confirmed it, but the signals point that way: he’s entering his 14th season on a one-year deal, and his longtime trainer, Hall of Famer Cris Carter, has already called it Kelce’s “last dance” before a likely trip to Canton.
Carter’s comment came after Kelce’s July wedding to Taylor Swift, when he posted that Kelce was preparing for “THE LAST DANCE. Next stop Canton/HOF.” Kelce hasn’t said any such thing publicly, and he’s already fielding retirement questions at training camp, which tends to happen to future Hall of Famers whether they’ve earned it that particular year or not. Andy Reid has declined to push him toward a decision: “We all love Trav. Trav can still play… I just know there’s time,” Reid said this summer, while also praising Kelce’s camp work ethic: the oldest guy on the roster, Reid said, and still the hardest to get to leave the practice field.
None of that erases 2025 itself: an 84th career touchdown that broke Priest Holmes’ franchise record, and a Pro Bowl berth in his age-35 season. (A wedding to a global pop star has a way of making even an ordinary offseason look like the final chapter of something.) Whatever this year turns out to be, it isn’t a farewell tour yet. Kelce hasn’t called it that, and neither has anyone in his building.
The more urgent question for Monday is what Mahomes looks like now. He was fully cleared for training camp, missed no reps, and by all accounts cleared every hurdle the rehab threw at him; Reid says there’s a “pretty good chance” he starts. Mahomes has said the injury will “probably” affect him for the rest of his career, even though the knee “feels great” right now (an honest hedge, or a quarterback managing expectations before anyone else can manage them for him).

Nine months isn’t a full recovery from a torn ACL and LCL by most timelines. It’s just fast enough that everyone will be watching the first hit he takes on Monday.
Denver Isn’t Just Happy to Be Here
It would be a mistake to treat Denver as the lucky bystander in all of this. The Broncos won the AFC West at 13-3, their first division title in a decade, then beat Buffalo 33-30 in overtime in the divisional round. Bo Nix suffered a season-ending ankle injury on the second-to-last play of that win, which meant Jarrett Stidham started the AFC Championship Game. Denver lost that one to New England, 10-7.
(Losing a conference title by three points with your backup quarterback tends to raise a fanbase’s expectations, not lower them.)
Nix returns for his third season off a year in which he threw for 3,931 yards and 25 touchdowns on a league-high 612 attempts. No quarterback in NFL history has reached 20-plus wins, 7,500-plus passing yards and 50 touchdowns through his first two seasons the way Nix has. Denver traded for Jaylen Waddle this offseason to give him another target; Kansas City answered by adding running back Kenneth Walker III. Sean Payton has been unbothered by outside skepticism of his quarterback, saying earlier this summer that quarterbacks are “measured by wins, measured by certain things, and ultimately that’s how history will be written,” and separately predicted Nix becomes a superstar within two years.
So which is it: was last season a fluke, or the start of the closing chapter? I think it’s neither in the clean way either side wants. The Chiefs’ collapse had a specific, identifiable cause — the quarterback got hurt, and the position fell apart behind him. That’s exactly the kind of failure that’s fixable if Mahomes is actually right on Monday. That’s a real if, not a formality. But even a healthy Mahomes returns to a division that’s gotten harder, not easier, against a Broncos team that improved without needing a miracle to do it. Kansas City’s championship window isn’t shut. It’s no longer something the Chiefs get to assume is still open by default, which is a different problem than the one they’re used to solving.
Monday won’t settle any of this by itself. But it will tell us something no offseason projection can: whether Mahomes’ knee holds up under live pressure, whether Kansas City’s revamped pieces around him look like answers or Band-Aids, and whether Denver’s defense is good enough to make the Chiefs feel every bit of the pressure that comes with getting the league’s full attention for one night. For the rest of our Week 1 coverage, watch how many other contenders are quietly answering similar questions, just without an entire night to themselves.
