I think Kiffin and maybe Dooley could have done that with Mac Jones and Bama-like talent at the OL and skill positions. Maybe even Butch too. You have to remember, at one point Bama’s entire 1st string defense was 5-stars, and the OL is basically NFL. It’s not hard to make average players and average coaches look good with ridiculous talent. Hell - Pruitt was an otherworldly DC at Bama and what is he doing now? The list is long and distinguished of the great coaches at Bama that didn’t squat outside of that system.
Saban gets credit for making it work and putting the system together, which makes him the GOAT with the results. But I don’t think he could replicate what he did at Bama anywhere else.
