Power-rating comparison
Why the model has the Lions by 7.5
The model does not think this one is close. The Lions rate 8th of 32 at +2.4, the Saints 26th at -2.4, and once home field is applied the line lands on the Lions by 7.5 — 70% to win. That is the 1st-widest gap among the 16 games on the Week 1 board. A preseason rating spread this size is not a promise: it says nothing about turnovers, health, or a defense that shows up different than last year. What it does say is that the Saints need the price to be wrong, not the matchup.
The defense wins the headline matchup here: the Lions grade +0.6 on that side of the ball (7th of 32) against a Saints offense at -1.6 (27th) — 2.2 points the wrong way for the offense. Going the other direction, the Lions offense (+1.2, 10th) meets the Saints defense (-0.5, 14th), a 1.7-point gap. One more tilt worth noting: special teams favors the Lions +0.6 (11th of 32) to -0.3 (32nd).
Zoom out to the full season and the model projects the Lions at 9.8 wins (favored in 13 of 17) and the Saints at 7.7 (favored in 7) — 2.1 wins apart across the year. By win probability this is the 14th-hardest game on the Lions' schedule and the 1st-hardest on the Saints'. Nothing on the Saints' schedule projects harder than this one.
Recent history, for context only: 11 regular-season meetings since 2002, 6-5 in the Lions' favour, plus 1 playoff game. They last met in 2023: Lions won 33-28 in December. Over their last 4 meetings the Lions are 2-2. It is not an input to the line — rosters turn over faster than series records do.
A note on confidence this high: the model has only been this sure 312 times in 3266 walk-forward games from 2013-2024. Teams it put in the 70-75% range won 71% of those. So a 70% Lions number is well supported by the record, and still loses about 29 times in 100 — which is exactly why the position is a price question, not a certainty question.
Kalshi's KXNFLGAME-26SEP13NODET contract implies 75% for the Lions against our 70% — a 4.5-point gap. That is inside our 5-point threshold, so we pass — the market and the model are telling the same story.

Saints vs Lions — frequently asked
Who is favored in Saints vs Lions in Week 1?
Our power-rating model favors the Lions by 7.5 points, a 70% win probability over the Saints. Kalshi's KXNFLGAME-26SEP13NODET market implies 75% for the Lions — a 4.5pp agreement with the model.
What would it take for the Saints to win?
The 7.5-point line comes from a 4.8-point rating gap, and a single-game margin has roughly a 13.5-point standard deviation around it — which is why the Saints still project at 30% rather than zero. Their best structural path is the unit matchup they win on paper. Ratings do not price injuries or turnover luck, which is where most upsets actually come from.
