The two teams
Illinois
Illinois is in year 6 under Bret Bielema, whose offenses have been balanced. The strengths are on both sides of the ball, led by 22nd on first and second down. The way in is 133rd at hitting chunk plays.
On fourth down he goes for it about as often as his peers do from the same spots (−0.1%). Against what the expected-points model recommends he is −27.5% — the profession as a whole is negative on this.
Illinois has played 2 games against a genuinely tough 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 (OSU Elo 1983, ILL Elo 1589 for reference), with home-field advantage. That projects OSU -25.5 (96% 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).

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.
