Power-rating comparison
Reading the Week 1 line on Falcons–Steelers
Week 1 is the widest-error week of the season for every model, ours included — nothing about 2026 is on tape yet, and the ratings are priors, not measurements. With that stated plainly: the Steelers rate -0.5 (19th), the Falcons -0.3 (16th), and the model opens on the Steelers by 2.5, 57% to win. Every number on this page will move more between now and kickoff than it will in any week that follows.
Season-long, the model can barely split them: 8.2 projected wins for the Steelers against 8.6 for the Falcons, favored in 10 and 8 of their 17 respectively. Two teams heading for the same neighborhood in the standings tend to produce exactly this kind of line. This game sits 14th-hardest on the Steelers' schedule and 3rd-hardest on the Falcons'.
No unit matchup in this game separates by even a point on our scale. The Steelers grade -0.5 on offense (21st of 32) and -0.5 on defense (13th); the Falcons +0.2 (19th) and -0.6 (17th). Evenly-graded units on both sides of the ball is exactly the profile that produces a model line built from nothing but home field.
One team has owned this series: the Steelers are 5-1 in 7 regular-season meetings since 2002. They last met in 2024: Steelers won 18-10 in September. Over their last 4 meetings the Steelers are 4-0. 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 Steelers at 57% are in that band. A margin that thin is why we would rather wait for a price than call it a lean.
Kalshi's KXNFLGAME-26SEP13ATLPIT contract implies 59% for the Steelers against our 57% — a 2.3-point gap. That is inside our 5-point threshold, so we pass — the market and the model are telling the same story.

Falcons vs Steelers — frequently asked
Who is favored in Falcons vs Steelers in Week 1?
Our power-rating model favors the Steelers by 2.5 points, a 57% win probability over the Falcons. Kalshi's KXNFLGAME-26SEP13ATLPIT market implies 59% for the Steelers — a 2.3pp agreement with the model.
How reliable is a Week 1 model line?
Less reliable than any other week, and we would rather say so. The -0.5 / -0.3 ratings behind the 2.5-point line are preseason priors built from prior-season performance and roster change — no 2026 snaps are in them. Week 1 is the point of maximum uncertainty for the model and for the market, which is also why prices move most in it.
