Estimate is uncertain

Comparable games put Iowa's chance of winning by at least 28 at about 59%. Historically, the market shaded about 2.7 points toward Northern Illinois (average-estimate range 1.9–4.1), but actual results were too noisy to treat that as a dependable OV Line adjustment.

Estimate revised after kickoff

This locked page preserves the estimate OnVarsity showed before kickoff. The study was revalidated afterward and contributes zero points to new matchups.

Jeremy Hecklinski is expected to start at quarterback for Iowa with only 2 career passing attempts. In 17 comparable FBS-FBS openers with a named starter below 50 career attempts, markets averaged about 0.9 points away from that team after ordinary game-flow context was accounted for.

Other conditions we evaluatedNot included in the estimate

These conditions were relevant to this matchup, but their studies did not justify a separate Factor estimate. That does not mean they never matter: some may already be reflected in preseason information or the opening market, may overlap with another Factor, or may simply lack a reliable additional effect.

Season Opener with a New Head Coach No separate adjustment

Rob Harley begins his first Northern Illinois season; Iowa returns Kirk Ferentz. Across 38 comparable games, markets averaged 0.86 points toward the returning coach at the final recorded line in the full sample. However, the 24 games with provider-level opening data centered near zero at opening, at the final recorded line, and in later movement. We identify the condition for transparency but apply no Factor points.
