Cowboys vs Rams prediction and pick

Our Dallas Cowboys at Los Angeles Rams pick: Rams by 4.7, 64% to win. The forecast starts from what each team’s play has been worth once the luck is adjusted for, adds last season, who starts at quarterback and who is out hurt, and home field. No betting information goes in.

An early look, 12 weeks ahead: it sharpens as the game comes up. Updated every day until kickoff, then frozen and scored. After the game this page shows who deserved to win.

Why the curves are so wide: luck. Even with both teams’ strength known exactly, one game’s bounces, kicks, calls and sequencing move the final margin by about ±12.1 points (one standard deviation, measured from every play since 2019). These forecasts carry ±13.4, so about 81% of the width is that luck; the rest is what nobody knows yet about the teams. That is why a 7-point favorite still loses about 3 times in 10.
