That must be why all these other schools rent out stadiums...oh..wait...
Not all schools have the opportunity to lease professional sports facilities like we do. Sharing stadiums with MLS teams and colleges significantly improves utilization for a facility that would be hardly used. They are in better shape if they can hold concerts, monster trucks, and other short term events. Pitt, Miami, San Diego St, Tulane, UMass, Georgia St, Temple, Tennessee st. all operate using this model. Facilities that host NHL and NBA teams probably have the highest utilization, followed by MLB.
