Game recap

Broncos @ Chiefs

2026 Wk 1 · KC 31, DEN 10

A Week 1 number this far below a team's own floor points at the matchup more than at random noise. Denver took 4 sacks and lost 2 turnovers, and its play count of 46 is the smallest of any Week 1 offense in the table, which means drives ended early and often. One game cannot reset a 2025 baseline, but minus 0.344 sits below every one of Denver's 2025 regular season games, and the lowest of those was minus 0.252.

FanIQ Research · September 15, 2026 · 7 facts, every one from the play-by-play

Denver ran 46 pass and run plays for 177 yards and averaged minus 0.344 EPA per play. All 32 offenses played in Week 1 and none was lower. The same offense finished 2025 at plus 0.050 per play, 10th in the league. Its lowest 2025 game, Week 10 against the Raiders, was minus 0.252.

Why it matters. A Week 1 number this far below a team's own floor points at the matchup more than at random noise. Denver took 4 sacks and lost 2 turnovers, and its play count of 46 is the smallest of any Week 1 offense in the table, which means drives ended early and often. One game cannot reset a 2025 baseline, but minus 0.344 sits below every one of Denver's 2025 regular season games, and the lowest of those was minus 0.252.

Kansas City ran for 224 yards. No Chiefs game in 2025 reached 160, and no Broncos opponent in 2025 reached 170.

2025 Wk 7 vs NYG	32	119

Kansas City gained 224 yards on 35 runs, second in Week 1 behind Chicago's 291. Higher is better here for the offense. The Chiefs' best rushing game of 2025 was 158 yards at Jacksonville. Denver's worst rushing day allowed in 2025 was 167 yards at Indianapolis. This game beat both marks by more than 55 yards.

Why it matters. Both baselines moved in the same direction, so the number is not just a bad night for one unit. Kansas City did not run like this in any 2025 regular season game, and Denver did not allow it in any 2025 regular season game. The passing line was ordinary, 172 net passing yards on 29 dropbacks, so the ground game produced most of the 396 total yards. A 60 yard touchdown run accounts for a big share of the total, which is the caution when reading one game.

Kenneth Walker III led every Week 1 rusher with 173 yards, and his 60 yard touchdown was the second longest run of the week.

Player	Team	Yards	TD
Kyle Monangai	CHI	61	Yes
Kenneth Walker III	KC	60	Yes
Saquon Barkley	PHI	42	No
Derrick Henry	BAL	32	Yes

Walker carried 23 times for 173 yards and a touchdown, 17 yards clear of Jahmyr Gibbs on 6 fewer carries. He also caught 3 passes for 18 yards and a second touchdown. His 60 yard score at 12:53 of the third quarter pushed the lead to 21 to 7. Only Kyle Monangai's 61 yard run in Chicago was longer this week.

Why it matters. A Week 1 rushing title is a small sample milestone, but the shape of the line matters for Kansas City. Walker's 7.5 yards per carry came in a game where Patrick Mahomes threw for 184 yards, so the offense scored 31 points without a big passing day. Denver's run defense allowed 167 yards at most in any 2025 game, so a single back beating that number alone is the part that stands out.

Denver never led. The game sat at 7 to 7 for 17:07 of clock, and Kansas City led on all 91 plays after that.

Plays with a possession team, by who was ahead

State	Plays

Kansas City scored first on a Mahomes scramble and Denver answered on its next drive. From 3:53 in the first quarter to 1:46 in the second, the score stayed 7 to 7. Rashee Rice's touchdown broke the tie, and the Chiefs led on every one of the remaining 91 plays. The largest lead was 21 points, and Denver's only second half points were a field goal.

Why it matters. A game with zero lead changes and a single tie window is not a comeback story, so the useful read is where the tie broke. It broke on a late first half drive, which is the possession that decides most one sided games: the leader gets the ball back after halftime with the score already tilted. Kansas City then added 17 points across the third and early fourth quarter before Denver's offense had produced a second score.

Denver gained 64 yards on 21 second half plays and averaged minus 0.591 EPA per play after halftime.

DEN	2nd	21	64	3	2	-0.591	28.6%
KC	1st	37	182	11	0	0.165	45.9%
KC	2nd	27	214	7	2	0.164	37.0%

Denver's first half was poor but functional: 25 plays, 113 yards, 5 first downs, minus 0.137 per play. After halftime it ran 21 plays for 64 yards and 3 first downs at minus 0.591 per play, with a success rate of 28.6 percent. Kansas City's per play number barely moved between halves, 0.165 and then 0.164, while its yards rose from 182 to 214 on fewer plays.

Why it matters. The halves tell different stories for the two offenses. Kansas City stayed flat, which means it did not need to change anything to keep scoring. Denver's collapse from minus 0.137 to minus 0.591 is the larger swing, and it came while trailing, when the offense had to throw and Kansas City could rush the passer. Two of Denver's 4 sacks came after halftime, one of them a strip sack recovered by Kansas City.

Denver converted 2 of 12 third downs. It converted 42.7 percent of them in 2025, and only one 2025 game was worse.

2025 Wk 6 at NYJ	15	5	33.3%
2025 Wk 10 vs LV	15	5	33.3%

Higher is better for the offense. Denver came in at 42.7 percent for 2025 and converted 16.7 percent here. Kansas City came in at 38.0 percent and converted 56.3 percent. The two teams flipped: Denver had the better 2025 rate by almost 5 points, and Kansas City won this game's rate by almost 40. Only Denver's Week 3 game at the Chargers in 2025, 2 of 13, was lower than this one.

Why it matters. Third down is where the drive count in this game came from. Denver faced 12 third downs and kept the ball on 2, which is why its offense ran only 46 plays. Kansas City faced 16 and kept the ball on 9, which is how it ran 64 plays and 35 of them on the ground. The 12 attempt sample is small enough that two plays move the rate a lot, but the direction matches every other efficiency number from this game.

Denver had beaten Kansas City three straight times. The Chiefs answered with one of only seven wins by 20 or more in the series since 1999.

2026	1	Home	31	10	KC

That is the complete list of 20 point Chiefs wins in the series since 1999. This one ranks fifth by margin. It also ended a run of three straight Denver wins, which started with a 38 to 0 shutout in Week 18 of 2024 and included a 20 to 13 Denver win at Kansas City in Week 17 of 2025.

Why it matters. Three straight losses to a division opponent is unusual for this Kansas City era, and the three came by 38, 3, and 7 points. A 21 point response in the first meeting of the new season does not erase the streak, but it is the fifth largest Chiefs margin in the series since 1999, and the first Chiefs win over Denver since Week 10 of 2024.
