A data-backed preview built from the committed 2026 preseason SP+ snapshot, the CFBD schedule, and Bill Connelly's extracted conference preview tables. Every projection traces to a stored payload.
Illinois Fighting Illini enters 2026 rated 9th in the Big Ten (#33 nationally). The profile is an above average defense (#44) paired with a strong offense (#28). Schedule math puts the season at 7.1 expected wins, against Connelly's independent 7.0. 2 games project as clear underdog spots (Ohio State, Oregon). The season turns on 4 close games: Maryland, UCLA, Iowa, Northwestern.
Bars run left (worst) to right (best): a longer bar is a better national rank. Special-teams ratings are volatile year to year.
