There has already been some quarterback shuffling in the Big 12 after only two games. Skylar Thompson’s sixth year in Kansas State’s program is on hold because of a knee injury that will keep him out indefinitely. Fourth-year Iowa State starter Brock Purdy was benched in the fourth quarter of the biggest home game in program history, though he is expected to be stay the starter. First-year Texas coach Steve Sarkisian is already changing starters. He’ll replace inconsistent redshirt freshman Hudson Card with junior Casey Thompson.
