Written before the game and kept as published. Final: Arizona Cardinals 18, Los Angeles Rams 16 — the graded call is above.
The model does not think this one is close. The Rams rate 3rd of 32 at +3.0, the Cardinals 31st at -4.4, and once home field is applied the line lands on the Rams by 9.5 — 75% to win. That is the widest gap among the 14 games on the Week 6 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 Cardinals need the price to be wrong, not the matchup.
The sharpest unit gap in the game runs one way: the Rams offense grades +2.9 (5th of 32) against a Cardinals defense at -3.8 (30th) — 6.6 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 Rams defense (+0.3, 6th), a 0.8-point gap.
Zoom out to the full season and the model projects the Rams at 8.8 wins (favored in 13 of 17) and the Cardinals at 6.0 (favored in 2) — 2.8 wins apart across the year. By win probability this is the 17th-hardest game on the Rams' schedule and the 2nd-hardest on the Cardinals'. It is the softest spot on the Rams' entire schedule.
On the standings side, NFC West games are the ones that decide the tiebreakers. Head-to-head record is the first tiebreaker between two teams in the same division, and division record is the next — so the value of this result is not just the win column. They meet again in Week 10, which makes a sweep the outcome with real leverage on the NFC West race.
Recent history, for context only: 48 regular-season meetings since 2002, 28-20 in the Rams' favour, plus 2 playoff games. They last met in 2025: Rams won 37-20 in January. Over their last 4 meetings the Rams are 3-1. 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 75% Rams 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.
