Well, unless things get really strange, the 2 situations would be about as far apart as the edges of the universe.
2006: Fresh off a debilitating probation, multiple poor choices at head coach, and the rise of regional rival programs, made Alabama a not-too-enticing project for a quality head coach.
20XX: Decade plus of championship level football, loaded roster of talent, constantly upgraded facilities to be in the upper echelon of College Football programs.
The only things I could see getting in the way of the future, is expectations driving away coaches and the university administrations/Good Ole Boy Network deciding they know what's good for the football program and attempt to run it (one of the ongoing issues after Bryant was this). Saban worked because he came in and he runs the show.
Next guy needs to be some sort of CEO type, and hope he hires good people.
Personally, I'd put Jimbo or Kirby over Dabo, simply because Dabo is a little bit too "goofy" but he could work. I doubt Alabama would make any push on Urban or Harbaugh.
