Team
Denver Broncos
AFC West
Winning despite a negative interception ledger is the signature of a defense strong enough to absorb mistakes, and 2025 Denver had one. But it is also a fragility marker: the games a team wins while losing the ball battle are exactly the wins that vanish when the defense has an ordinary day. It is one more reason the 14-3 record overstates the baseline.
The 14-3 season, examined
Denver went 5-2 on days it lost the interception battle. Almost nobody survives that.

Few things decide a single Sunday like the turnover battle, and Denver spent 2025 on the wrong side of it more often than a 14-win team should: the offense threw 11 interceptions against just 10 taken, and the team lost the interception battle outright in 7 games. It went 5-2 in those games anyway. The pass rush and the one-score magic papered over a ball-security ledger that, for most teams, is where seasons go to die.
Why it matters. Winning despite a negative interception ledger is the signature of a defense strong enough to absorb mistakes, and 2025 Denver had one. But it is also a fragility marker: the games a team wins while losing the ball battle are exactly the wins that vanish when the defense has an ordinary day. It is one more reason the 14-3 record overstates the baseline.
The margin says Denver is an 11-win team that went 14-3. Expect the record to come back to the margin.

| Won 2.5+ more games than points said | 19 | avg 12.2 wins became 9.4; 13 of 19 fell |
Denver's +90 point differential is an excellent number that maps to about 10.9 wins, not 14; the extra three came from an 11-2 record in one-score games. Both of the relevant histories point the same way: 12-win teams since 1999 fell to an average of 9.6 wins the next year (barely three in ten repeated), and teams that beat their points expectation by 2.5+ wins fell by an average of about three. The gradeable call: Denver stays a contender in 2026 but lands closer to 10-11 wins than 14.
Why it matters. This is a regression call about the record, not the roster: the differential says Denver's true level is that of a 10-11 win team, which is still playoff-grade. The distinction matters for expectations, because a fall from 14 to 10 wins with the same underlying quality will read as decline when it is actually just the close-game coin returning to center.
The pass rush identity
Denver got to the quarterback more than any defense in football, and it came out of nowhere.

| 2024 | 9.4% | 63 | 1st |
| 2025 | 10.3% | 68 | 1st |
Denver's 8.9% sack rate leads the entire NFL over 2023-2025, and the recent surge is violent: from 26th in 2022 to first in both 2024 and 2025. The 68 sacks in 2025 are the 2nd-most by any team in a single season since 1999, trailing only the 2022 Eagles (70). Two years before that, this was a middle-of-the-pack pass rush.
Why it matters. Sack rate per dropback is a cleaner pressure signal than raw totals because it adjusts for how often a defense faces a passer. Denver did not inherit this identity; it built it across two drafts and a coaching change, and the jump from 26th to first is one of the steepest pass-rush rises in the league. A defense that gets home on nearly one in ten dropbacks dictates the down without help.
Best pass rush in football, and one of the easiest to throw over. Denver's defense is a study in extremes.

| 22 | CAR | +0.419 | 155 |
Denver wins the line of scrimmage like nobody else, 1st in sack rate, 2nd in 3rd-down stops, then gives most of it back over the top: 21st in deep-ball EPA allowed. It is the natural cost of an aggressive front. When the rush gets home, drives die; when the quarterback survives the first beat, the safeties are exposed. Forcing turnovers (17th) is also not part of the recipe.
Why it matters. A defense this good at pressure but this soft deep is a coverage-versus-rush tradeoff, not a contradiction. The blitz and four-man pressure that produce the league's top sack rate leave fewer bodies deep, so the chunk plays Denver allows are the price of the chaos it creates. Beating them means protecting long enough to find the shot, which few offenses managed.
On 3rd down, only one defense in the league gets off the field more often than Denver.

| 2 | LAC | 13.4% | 66 |
| 3 | MIA | 12.3% | 57 |
| 4 | DEN | 12.3% | 64 |
Denver stops 64.4% of 3rd downs, 2nd only to Cleveland (65.5%) over the three-year span, and the lever is the pass rush: it sacks the quarterback on 12.3% of 3rd-down dropbacks (4th in the NFL). The down made for conversions is the down Denver wins. Get to 3rd-and-medium against the Broncos and the most likely outcome is a punt.
Why it matters. 3rd-down defense is the truest down-to-down measure of a unit that ends drives, and Denver's elite rate is fueled by a front that turns obvious passing downs into sacks. Pairing a top-2 stop rate with a top-4 money-down sack rate is the mechanism, not a coincidence: pressure on the most predictable pass of the series is how you finish ranked just behind the best defense in football.
Mile High's real edge is the 4th quarter: nobody's home defense strangles you late like Denver's.

|---|---|---|
| Home (Mile High) | -0.107 | -0.266 |
| Away | -0.017 | -0.060 |
Denver's defense allows -0.266 EPA per play in the 4th quarter at home, the stingiest closing-quarter home defense in the NFL. The split is brutal: the same unit allows -0.060 away in the 4th, so the altitude edge is worth roughly 0.2 EPA per late play. Visitors run out of air exactly when the game is decided. Home margin since 2023 is +8.0 per game; away it is -2.4.
Why it matters. The Mile High advantage is usually framed as a thin-air offense or a loud crowd, but the data points at the defense and at one quarter in particular. Opponents arriving from sea level fade physically late, and a pass rush this good compounds a tiring offensive line. That is why Denver wins the nervy ones at home and grinds on the road.
Nix and the lead formula
Bo Nix's offense ranked top-10 in efficiency while throwing the ball less accurately than expected. Scheme, not aim.
Anomaly2025 offenses: EPA/play vs completion % over expected (CPOE)
| Off rank | Team | EPA/play | CPOE | CPOE rank |
|---|---|---|---|---|
| 1 | NE | +0.159 | +10.68 | 1st |
| 3 | BUF | +0.136 | +3.82 | 5th |
| 6 | SF | +0.088 | +5.43 | 3rd |
| 8 | CHI | +0.079 | -3.43 | 29th |
| 10 | DEN | +0.050 | -1.33 | 23rd |
| 11 | KC | +0.035 | -0.89 | 21st |
Denver's 2025 offense finished 10th in EPA per play while its passes landed 1.33% below expectation, 23rd in CPOE. Almost every top-10 offense paired efficiency with accuracy; Denver and Chicago were the exceptions, producing points despite below-average ball placement. The value came from elsewhere: shotgun snaps graded +0.072 EPA versus +0.009 under center, and the offense was sharpest while trailing (+0.083 EPA).
Why it matters. CPOE isolates the quarterback's accuracy from scheme and play-calling. Denver's gap between strong efficiency and weak CPOE means Sean Payton's design, spacing, run threat, and shot selection, was doing the heavy lifting more than pinpoint throwing. That is a sustainable model if the structure holds, but it flags accuracy as the clearest place a young passer can still add value.
Denver still takes its shots downhill. It just rarely connects: 21st in deep-ball completion %.

| 2024 | 74 | 36.5% | +0.35 |
| 2025 | 72 | 34.7% | +0.42 |
Denver does not avoid the deep shot. With 220 attempts of 20-plus air yards over three years, the volume is upper-middle of the league. The connection rate is the problem: 34.1%, 21st in the NFL, in the same neighborhood as Carolina and Chicago. The encouraging note is that when the shots do land, they pay (+0.42 EPA per deep ball in 2025), so the cap here is accuracy and timing, not aggression.
Why it matters. A healthy deep-ball completion rate stretches a defense and opens the underneath game; a poor one lets safeties cheat down. Denver keeps calling deep shots, so the ceiling on this offense is tied to a young quarterback's downfield accuracy improving. The decent EPA-per-completion says the routes and matchups are there. The misses are leaving points on the field.
The formula: get in front, then hand the game to the run and the defense. It even won the ugly ones.
SplitDEN 2025 run rate by game script (regular season)

DEN 2025 record by points scored
| Points scored | Record |
|---|---|
| 20 or more | 10-3 |
| Under 20 | 4-0 |
Once ahead, Denver leaned on the ground game (46.4% run rate with a 7+ point lead versus 31.4% trailing) and let the league's best pass rush close. The wildest line on the ledger: 4-0 in games where the offense never reached 20 points. Across the last quarter century, teams that fall short of 20 usually lose; Denver won all four times it happened, which is the defense's achievement and a very hard trick to repeat.
Why it matters. The run-rate split is mostly the scoreboard talking, not a philosophy: leaders run, trailers throw. What is genuinely informative is the under-20 record. Winning four games without reaching 20 points requires a defense playing at a historic level, and it is precisely the kind of result that does not survive an ordinary defensive season. It marks 2025 as a ceiling outcome for this formula.
