versatile Iowa road grader with tackle-to-guard flexibility
Kallenberger built his Iowa profile on versatility, toughness, and a coach’s trust—he started nine of 22 career games across tackle and guard, including four starts at right tackle in the 2020 season, and he also handled left guard and right guard duties when the Hawkeyes needed help upfront[14][10]. He missed two games in the 2020 season because of injury, then chose to forgo a fifth year, so the big question is less about raw traits and more about immediate depth-value: if your room needs a reliable, multi-position lineman with proven Iowa-style grit, he fits the bill[14].
