Saban is a really good coach, but give him 6-6 talent, he's going 6-6. He's never, ever upset anyone. Bowden used to say, of great coaches "he can take his'n and beat yours'n, and take yours'n and beat his'n". Saban is not that guy. He's a guy that will step on anyone and break every rule to get Saban the players to get the wins.
At least 7 #1 recruiting classes in a row because of massive payola to players, cars, condos, "go if you want, and it doesn't interfere with football" academic requirements. He's running a pro organization, with a rabid fan base that will pay anything, and do anything, to win.
He cleared an extra 36 scholarships in his first four years by cutting players. Who else has been able to do that with impunity? Ole Miss started to under Freeze and he got crushed, then the SEC stepped in and stopped (or mildly slowed) it. By then Saban's cupboards were already overflowing. Ole Miss is also under investigation for Laremy Tunsil texting a coach that he needed more money ASAP. The exact same thing happened at Bama a few years before and the NCAA has yet to come within 100 miles of Tuscaloosa.
Bottom line, having your BFF as the NCAA president has allowed Bama to break every rule out there with impunity. That's why Bama is, has been and will continue to be the dominant force in CFB. Not because Saban is the GCOAT.
