What happened: No. 14 Iowa hosts Ohio State in a Top 25 matchup in Iowa City. The prior GameDay visit also featured the Buckeyes, a 38-17 Ohio State win.

Why it matters: The ranking puts Top 25 positioning on the line early in conference play. The combination of a sellout, stripe-out and national pregame show gives Iowa rare home spotlight against a road-tested visitor.

What to watch: Kickoff is set for 3:30 p.m. ET Saturday on CBS.
