Former Iowa football DE Brian Allen takes SEC leap
Former Iowa football DE Brian Allen made waves across the Big Ten and SEC landscape after officially announcing his transfer destination, choosing Vanderbilt for his final season of eligibility. The decision comes after Allen entered the NCAA transfer portal despite appearing on track for an expanded role in Iowa’s defensive rotation heading into 2026.

For Iowa, that bowl win carried historic significance. Longtime head coach Kirk Ferentz became the most successful bowl coach in Big Ten history after the Hawkeyes finished 9-4.
