Florida recruits get split between three major schools in state, and others nearby of course. UGA doesn't have that, with about half the population as FL. It's an advantage in recruiting. Ohio State has the same kind of advantage. But, yes, any program can slip, we see how USC has done of late. Texas is still recruiting well.
The most stable program in my view is Ohio State, I can't see how they are likely at all to slide very far. And they have never been bad for long.
