Good point, but there is a USF coaching staff you could make that have people with actual experience
HC: Jim Leavitt
DC: James Rowe - played baseball at USF. But since then was DC at Valdosta State and they led D2 in interceptions, 3 year defensive assistant for the Washington Commanders, Broyles award nominated DB coach at App State, DB's coach for the Colts, and now DB's coach for the Bears
Co-OC: Larry Scott - interim HC at Miami, OC at Tennessee, HC at Howard
Co-Oc: Marquell Blackwell (Co-OC at Houston and now RB's coach at Ole Miss)
LB coach: Auggie Sanchez - cerebral player who is the HC @ Seminole in Pinellas, leading them to 8-2 currently
Then you'd have the guys like Flowers & Kayvon Webster who have mentioned they would like to get into coaching be lower level assistants.
