Big 12 football schedule has some very big games on it. Here are 12 of the biggest, including Arizona State vs Iowa State, BYU vs Colorado.

On Tuesday morning, the Sun Devils released their official 2025 schedule, which includes several tough matchups as well as some favorable ones. Toward the end of the season, the schedule's degree of difficulty ramps up, so Arizona State will need to be playing its best ball come November.

ASU will play Iowa State in Ames on Nov. 1. That will be one of four road games, the others coming against Colorado, Utah, and Baylor. The Baylor game will be ASU's conference schedule opener on Sept. 21. Unlike last season, ASU does not have back-to-back road games this season.
