LB
Redshirt Senior
Iowa State transfer linebacker with 18 career tackles and special-teams value. Klosterman should be framed as experienced depth while Penn State sorts out its 2026 linebacker rotation.
John Klosterman is an Iowa State transfer linebacker whose Penn State value begins with experience and special-teams utility. He is not a headline transfer, but players with older eligibility and coverage-unit work can be important when a roster is being rebuilt.
Penn State lists Klosterman as a redshirt senior at 5-foot-11 and 229 pounds. His college production is more depth-oriented than star-level, with public roster reporting crediting him with 18 career tackles at Iowa State. That makes the profile useful for depth-chart context without pretending he is already locked into a major defensive role.
For 2026, Klosterman should be viewed as linebacker depth and a special-teams candidate. Penn State has to sort out defensive communication, run fits, and substitution packages, and older linebackers can earn trust by handling assignments cleanly even if they are not every-down players.
The page should watch for special-teams participation, second-unit linebacker reps, and whether he becomes a reliable emergency option. Those are realistic signals for his role.
