Details: how the model pick works
Projected margin SEA by 2.74; the line implied SEA by 3.00. Difference 0.26 points toward DEN (tiny). Differences under 0.5 points are labelled tiny and are within normal noise; 0.5–1.5 small, 1.5–3 moderate, 3 or more large.
The model pick is the side of the market line on which the model's unrounded projected margin fell when it was locked, at the first forecast with a market line (the rule for games from 1 to 20 October 2026). It stays the same if the line or the forecast changes later, and it is graded against the line it was locked at. Market line, model line, totals and the projected winner are from the latest forecast. The win probability belongs to the projected winner only; it is not a probability of finishing on that side of the line. For analysis and education only.
Result: Model pick correct · margin error 5.2 (actual margin DEN by 3.0).

Market inputs: SEA −2.5, total 40.5 · source: The Odds API (median of 9 US market lines) · provider updated 15 Oct, 22:45 UTC · retrieved by us 15 Oct, 22:45 UTC. These two numbers are inputs to the combined model; nothing else from the market is used.
Where the stats-only margin comes from
Points each part of the football data adds, in the colour of the team it favours.
From the football-only model, which uses no market line. Each bar points toward the team that part of the data favours; together they add up to the stats-only line. 4 groups under 0.05 points not shown. The groups overlap (a team that passes well also tends to score well), so read them together; this describes the fitted model, not football cause and effect. The model line is built from the market line and is not split this way.
How they rate
Percentile among the 28 teams playing this week, as of this forecast: 100 is the best in that measure, 50 is average. Defence measures are turned round so that higher is always better.
Offence
Defence
Quarterback
Per-play efficiency entering the game (EPA = expected points added), weighted towards recent games and, early in the season, still partly last season. These are the same football inputs the stats-only line is built from. Display only.
Coaching staff
SEA
| Head coach | Mike Macdonald | 3rd season |
| Offensive coordinator | Brian Fleury | New this season |
| Defensive coordinator | Aden Durde | 3rd season |
DEN
| Head coach | Sean Payton | 4th season |
| Offensive coordinator | Davis Webb | New this season |
| Defensive coordinator | Vance Joseph | 4th season |
Seasons in that role with this team ("+": at least, our records start in 2015). Staff from Wikipedia season pages (CC BY-SA); who calls the plays on game day is not always the coordinator. Display only: a test of giving last season less weight after coaching or roster changes (2019–2024) did not improve the forecasts, so the model does not use this.

From the official NFL injury report as carried by nflverse (data last changed 15 Oct, 12:37 UTC; we last checked 15 Oct, 23:45 UTC), shown as of kickoff. Most serious first. Depth chart: position and order on the team's latest depth chart before this report (usual starters in bold: first at the position, receivers 1–3). For this game, game statuses (Out, Doubtful, Questionable) come with the final report on Wednesday 14 Oct. The data feed can lag the league's own report, at times by a day or more, so check the official injury report on NFL.com and team announcements before kickoff. Display only: injuries other than at quarterback are not model inputs (tested; the market line usually reflects them).
What moved the combined model
| Feature | Effect (pts) |
|---|---|
| DEN offensive starting field position (yds to goal) | +0.03 |
| SEA pass defense EPA/dropback allowed | +0.02 |
| SEA opponent-adjusted defense rating | +0.02 |
| SEA defense success rate allowed | +0.02 |
| SEA defense EPA/play allowed | +0.02 |
Largest contributions to the model's adjustment of the market margin (positive favours DEN). This explains the fitted model, not football cause and effect. The adjustments are small because validation showed the market line is hard to improve on.
Weather (display only)
10.6 °C, wind 10.2 km/h (gusts 20.9), precipitation 0.0 mm at kickoff.
Open-Meteo forecast observed 2026-10-15 21:15 UTC, 3.0 h before kickoff. Weather is not a model input: it did not pass the feature-group evaluation (see Performance).

Every version is kept. The information cutoff of each version is its generation time. The highlighted row is the current version: the latest valid version generated before kickoff. Before kickoff it may still be replaced; at kickoff it is locked; once the game is final it is scored. Versions that failed validation are never shown as current or scored. "Public evidence" is GitHub's own record of when the file was first pushed, independent of this project's clock. Each version is also archived outside GitHub Actions: its SHA-256 hash, an RFC 3161 trusted timestamp (proves the exact file existed at that time) and an Internet Archive copy of the public file (checked byte-for-byte against the hash).
