Ohio State vs. Indiana Preview
Polymarket traders currently price Ohio State as a 2.5-point favorite with a 62% chance to win outright, despite Indiana’s unbeaten record and raucous home environment. That gap reflects a clear offensive talent edge, where Jeremiah Smith continues to produce explosive plays that few defenses in the country can contain. Indiana’s 22-game winning streak looks impressive on paper, but the schedule softened considerably after last year’s title run, and Saturday marks the Hoosiers’ first true test against a roster built with Ohio State’s level of speed and depth.
The pick here backs Ohio State -2.5. Ryan Day’s offense has shown it can control tempo against physical Big Ten fronts, and Indiana’s defense hasn't faced a receiving threat anywhere close to Smith’s caliber this season. Road environments have also rattled Ohio State before, but this group has responded well after its lone loss, tightening up on defense and leaning on a ground game that keeps Indiana’s pass rush off balance. A one-score margin feels right, and the value is with the Buckeyes covering a number still under a touchdown.
Indiana’s path to covering runs through its own home crowd and a defense that has forced issues all year, but matching Ohio State’s skill talent snap for snap remains the bigger obstacle. The over/under sits at 50.5, and both offenses have shown enough big-play ability to push this total north, though a tighter, more physical second half fits both coaching staffs' identities. Expect Ohio State to pull away late and cover behind a strong fourth quarter, with the final score landing in the 30-24 range.
Ohio State vs. Indiana Prediction: Ohio State -2.5 (54%)
