Written before the game and kept as published. Final: Denver Broncos 30, Arizona Cardinals 16 — the graded call is above.
The Broncos come in with 3 more days off — 7 days' rest for the Cardinals against 10 days' rest for the Broncos. We measured what that is worth across 3,120 games since 2013: about a tenth of a point per day, so roughly 0.3 points here. The market already charges for rest — closing lines move about 0.14 points per day of it — and rested teams have not beaten the close for it. The rest gap is real but small. What moves this game is the 6.2-point ratings gap, which has the Broncos by 2.5, 57% to win.
The Broncos come in off the Seahawks, the Cardinals off the Rams. Rest measures at about a tenth of a point per day (2013-2025), and the closing line already charges for it, so a normal-week gap is not where an edge comes from.
The sharpest unit gap in the game runs one way: the Broncos offense grades +0.4 (17th of 32) against a Cardinals defense at -3.8 (30th) — 4.1 points of separation on our scale, and the single biggest reason the line sits where it does. Going the other direction, the Cardinals offense (-0.6, 22nd) meets the Broncos defense (+1.2, 5th), a 1.7-point gap.
Zoom out to the full season and the model projects the Cardinals at 6.0 wins (favored in 2 of 17) and the Broncos at 10.9 (favored in 13) — 4.9 wins apart across the year. By win probability this is the 12th-hardest game on the Cardinals' schedule and the 13th-hardest on the Broncos'.
One team has owned this series: the Broncos are 5-1 in 6 regular-season meetings since 2002. They last met in 2022: Broncos won 24-15 in December. Over their last 4 meetings the Cardinals are 1-3. Worth saying plainly — the model does not know any of that. It reads 2026 ratings and nothing else, so a lopsided series is a story, not a number on this page.
Calibration check, because a near-even number is the easiest kind to overtrust: across 3266 walk-forward games (2013-2024) the model gave a side 55-60% in 797 of them, and those sides won 57%. The Broncos at 57% are in that band. A margin that thin is why we would rather wait for a price than call it a lean.
