The setup

Lions at Cardinals — Sunday, October 11 at 4:25 PM ET on Fox, State Farm Stadium in Glendale, AZ. An in-conference (NFC) matchup with tiebreaker weight down the road. The Lions arrive 2-2 (0-2 on the road); the Cardinals sit 1-3 (0-1 at home). FPI's season projection frames the stakes: the Cardinals at 4.8 wins with 0% playoff odds, the Lions at 9.6 and 51%.

The power ratings

FPI makes the Lions the better team by 6.6 points on a neutral field — +1.3 (No. 10) against -5.3 (No. 30) for the Cardinals. The unit matchups: when the Lions have it, their No. 4 EPA offense meets a Cardinals defense ranked 32nd; the Cardinals No. 22 offense draws a Lions defense ranked 29th.

What the computers think

ThePredictionTracker aggregates 48 computer systems on this game, and their average says the Lions by 3.7. They don't agree with each other: the most Lions-friendly system says Lions -14.5, the most Cardinals-friendly says Cardinals -2.6. Measured against the FanDuel line of Lions -5.5, that's 1.8 points of extra faith in the Cardinals — the kind of gap this model exists to catch.

The market

FanDuel has Lions -5.5 (-115 home / -105 away); the total sits 54.5; moneylines -245 / +200. The number has moved since the open — DK +8.5 to +5.5 on the home side, money leaning Cardinals.

The verdict

Blend the consensus with the ratings and the model's line is Lions -4, with the Lions winning 62% of the time. That's 1.5 points from the market, in the Cardinals' direction. The board's best number is Cardinals ML +205 at DraftKings: the model gives it 38% against a 33% break-even — +17.0% EV, 2.1u at quarter-Kelly.
