Kelly's system is opposite of what Richt runs...which is antiquated as hell.
Fitzgerald and Sweeney would def. listen, hell almost every coach in the country would at least listen.
If you fire Richt...you have to go get a big time, established coach that's shown he can win.
Richt's system with Bobo put up 42 PPG last year. Seemed to do fine then. An NFL system isn't antiquated as hell, it's just different than what is en vogue in CFB right now. Everything is cyclical. NFL systems will become popular again in CFB in time once defenses adapt enough to the spread.
