When Illinois faces Indiana tonight, it’s essentially a clash of the Big Ten’s two Playoff dark horses.
Although the instinct is to spotlight the Hoosiers’ offense, my Illinois vs. Indiana predictions point to their defense as the real key in this matchup.

Illinois vs Indiana prediction
Illinois vs Indiana best bet: Indiana -6.5 (-110 at FanDuel)
Blowout wins can cover up flaws. Recognizing those shortcomings can then yield later value.
Such is the case when looking back at Illinois’s route of Duke two weeks ago.
That was only a rout because of the Blue Devils’ five turnovers, obviously a hefty thought, but still a pertinent caveat.
Otherwise, Duke succeeded on more plays, held Illinois in check on the ground, and created havoc at a rate that would have flipped the script to a Blue Devils’ blowout if not for those repeated and egregious errors.
Illinois vs. Indiana, primetime NBC, and I will be most watching the Illinois offense vs. the Indiana defense.

Focus on holding the Illini rushing attack in check — gaining just 0.02 expected points per rush attempt and succeeding on only 15 of 38 rush attempts — and the defensive havoc plays on 18 of 73 snaps.
Illinois’ offense was not moving forward consistently enough. It was consistent enough to win a game with a +4 turnover margin, but without that gift, this offense may have worries.
Against one of the most efficient offenses in the country? That worry becomes reason enough to bet against the Illini.
Indiana’s defensive strength comes against the pass; thus, Illinois will have to rely on that already worrying ground game.
Even if it finds more success, relying on a rushing attack to keep up with one of the most efficient and explosive passing attacks in the country is not a recipe for staying within a touchdown on the road.
Illinois vs Indiana same-game parlay
The season may be young, but teams have been noticeably adverse to throwing the ball against Indiana, ranking No. 15 in rush rate over expected against.
Illinois is already better off running the ball than throwing it, so leaning away from Luke Altymer and toward Kaden Feagin makes sense on both sides of this conversation.

- Kaden Feagin Over 60.5 rushing yards
Our deep-ball SGP: Points Aplenty
Defensive havoc may end Illinois's hopes of an upset or even covering this spread, but defensive havoc can also create short-field scoring opportunities.
Whether that thought becomes reality or not, both these offenses have been relentless in converting quality drives into points this season, which should set up for a reasonably high-scoring game.
Illinois vs Indiana 4-leg SGP
- Indiana -6.5
- Over 52.5
- Luke Altmyer Under 219.5 passing yards

Illinois vs Indiana game predictions
Illinois vs Indiana moneyline prediction
Indiana is 14-0 outright as a favorite under Curt Cignetti, including 5-0 as a one-score favorite, something that should probably get more praise than it does.
Cignetti talks so brashly that it’s easy to overlook the fact that he consistently wins the games he’s expected to — a skill often underrated in college football.
Illinois vs Indiana spread prediction
Furthermore, Indiana is 11-3 against the spread as a favorite under Cignetti, including 5-0 ATS as a one-score favorite.
Illinois vs Indiana Over/Under prediction
Illinois’s possible offensive struggles should not doom this game to an Under. Running into a wall and/or losing yardage to havoc plays could then set up Indiana with advantageous field position.
And the Hoosiers will capitalize on that.
The biggest reason to trust this Over is the ability to capitalize. Illinois ranks No. 1 in the country in points per quality drive, while Indiana sits at No. 46, producing quality drives at the fifth-highest rate in the country.
Illinois vs Indiana odds
- Spread: Illinois +6.5 (-110 | Indiana -6.5 (-110)
