Jack Campbell’s impact at Iowa isn’t just about stats—it’s about leadership, work ethic, and setting the standard for those who came after him. As the 2025 NFL Combine wrapped up, several Iowa prospects reflected on how the Detroit Lions linebacker shaped their journeys.
Linebacker Jay Higgins, defensive back Jermari Harris, safety Sebastian Castro, tight end Luke Lachey, and running back Kaleb Johnson are among the Hawkeyes hoping to hear their names called in the upcoming draft. For them, Campbell wasn’t just a standout on the field—he was the example to follow.
“Jack was always in that elite group,” Higgins said, crediting Campbell for teaching him what it means to be a leader. The Lions’ 2023 first-round pick dominated at Iowa, racking up 305 tackles and winning the Butkus Award as college football’s top linebacker. Two years into his NFL career, he’s already made a name for himself in Detroit, tallying 226 tackles and earning a Pro Bowl alternate nod.
Campbell’s influence wasn’t just about performance—it was about mindset. His former teammates recall how he approached every detail with professionalism, treating college football like a stepping stone to the pros. Higgins, who took over as Iowa’s MIKE linebacker after Campbell, leaned on him for advice ahead of the Combine.
“He became a professional in the sense that everything matters,” Castro said. “Either you’re getting better or you’re getting worse.”
Campbell’s quiet, lead-by-example style pushed those around him to improve. Now, as his former Iowa teammates chase their NFL dreams, they’re hoping to follow the same path.
