Like I said, firing him and straddling the program with a huge buyout does nothing honestly. If anything, I'd bring in a GM that Mario would report to and the GM would oversee the program and Mario would have limited say so over all personnel decisions. This would be done so Mario can focus ONLY on game day preparation and in game management. His greatest deficiencies and that needs improvement. The portal, NIL, and building a roster of players should be overseen by someone else entirely. This follows the pro sports model. See Pat Riley for the Miami Heat. Or other set ups like that.
As far as names, I've always been an admirer of Chris Petersen and his leadership style and his approach to roster building. You could pull from the NFL ranks in terms of general managers or other personnel guys. I think Ohio State's GM could be persuaded if you gave him more power and a semi-bump in pay. Would Saban be interested in a non-coaching role but be given authority to build his roster and have the ability to hire and fire as he sees fit? I don't think so, but I would have never guessed that Belicheck is at North Carolina in 2024. So why not inquire. This is a win-win. Mario can stay as HC, but you have a more capable football mind making the bigger decisions and this allows Mario to narrow his responsibilities.
