Purdue vs Iowa prediction and pick

Our Purdue Boilermakers at Iowa Hawkeyes pick: Iowa by 24.3, 93% to win. The forecast rates every team against the opponents it has played, this season and last, and adds home field. No betting information goes in.

An early look, 7 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 ±17.0, so about 50% 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.
