1. Qb play is the most important and biggest factor for recent slump in the SEC downturn.
2. Recruiting around the country has improved especially on offense. The south still tends to have elite talent along the D-Line but not at every position any longer.
3. Scheduling: take a look at an ACC schedule or Pac 12 schedule, these teams do have to play in an enviroment like UGA and then AU back to back weeks.
4. Lack of dynamic offenses, I think that a lot of schools outside of the sec have better offensive schemes.
5. Saban: The fact that they recruit at such a high level and have 5 star guys two and three deep is bad for college football and especially the SEC.
6. Coaching: who would want to deal with the pressure at a school like LSU who are already talking about firing a coach 3-4 games in to the season?
There is a lot of truth in this post, but I would like to add one more thing.
Almost every school outside of Alabama that maybe could challenge Saban does is going through a tough time. Most have made bad choices for their head coach.
It would take the right guy given time to build something close to what Alabama has. Ole Miss tried to do it cutting corners. Tenn hired the wrong guy, so did LSU. The only one right now that is close to taking that next step is Kirby Smart, but he still has some way to go.
You have to have the right combination or coach, tradition to get the recruits and patience in the fan base. The likely hood of that happening is slim in the SEC. Dabo seems to have done it in the ACC, but he doesn't have to recruit against all of the SEC.
I think that Saban will rule unless he retires, moves to another position, get embroiled in an NCAA investigation or some other major shitstorm, or dies.
