I believe not only has it changed forever, its still in the middle of that major change. Some programs like Alabama and Georgia had a head start with solid foundations in administration and real depth on the field. While we were wandering in the wilderness, They have been at the very top, for a long time, so its had a different affect on them. Sooner or later it'll all catch up to them and things will be a little more even.
Not making excuses, it just is what it is. And a little nugget for the haters, Heupel hasn't been as good as Saban and Smart. Maybe he never will. Nobody knows. But he beat Saban and he came close to beating Kirby this year. It hasn't been this exciting in years on the Hill and my mind won't comprehend some of the hate being spewed by some.
I don't like most of the changes, but I know its like everything else I have zero control of, like the woo. Enjoy it best I can or just suck it up. Bitching whining and moaning about it does nothing but make everyone around you as miserable as you are.
