The two teams
Iowa
Iowa is in year 13 under Kirk Ferentz, whose offenses have been balanced. The strengths are on both sides of the ball, led by 8th at keeping everything in front of them. The way in is 137th at hitting chunk plays.
On fourth down he goes for it less often than his peers do from the same spots (−4.5%). Against what the expected-points model recommends he is −43.0% — the profession as a whole is negative on this.
Iowa has played 1 game against an average slate, adjusted for here. That football carries about 0% of what is below; the rest is still the preseason projection.

Ranks are national. Nothing here is last season's number — carrying one forward is measurably worse than saying nothing — and in-season figures are adjusted for who was actually played. This describes the matchup; it is not a prediction and not a pick.
Head coaches only — there is no free feed for coordinators, so on a program where the head coach does not call the offense this describes the staff he hired. Play-calling identity is a style, not a grade: throwing more than the situations warrant is not better than throwing less than they warrant.
Model prediction
how the number is builtOur model simulates the game drive by drive from each side's opponent-adjusted efficiency (ILL Elo 1587, IOWA Elo 1841 for reference), with home-field advantage. That projects ILL +3 (42% to win), essentially in line with the market.
Why that percentage is worth reading: across 604 graded in-season games, the calls this model put near 58% came in at 58.2%. The full calibration table is published, bin by bin. Early in the season the cold-start path runs instead and calibrates less well (Brier 0.2028 against 0.1889).

Each bar runs from last in the country on the left to 1st on the right. The filled span is the gap between the offense and the defense it faces.

Bold is the side ahead. CORE strips the situation from every play and solves the schedule out across the league, so these compare two teams that never met.
