Iowa returns eight players on its defense from a group that finished the 2021 season as the 13th-ranked scoring defense (19.2 points allowed per game) in the country. Star linebacker Jack Campbell returns to anchor the unit.

Ohio State looks to rebound this 2022 season with on defense after finishing 38th in points allowed per game (22.8). Jim Knowles was brought in as DC to fix the unit and is tasked with producing a top-10 unit immediately.

Wisconsin lost 8 full-time starters from last season on a defense that finished 4th in points allowed per game (16.2) and 1st in rushing yards allowed per game (64.8) and total yards allowed per game (239.1). The Badgers will have a defense that will potentially replicate those numbers.
