I don't agree with their scheduling strategy, I absolutely hate the FCS crap, but it's not much different than other leagues. Maybe one game. When you've got a 90,000 seat stadium I suppose that makes a difference too in how you approach scheduling as for the willingness to play road games, just from a financial standpoint.
I just think it's ignorant to think that the SEC's success is tied to their scheduling or some other bias in the media or whatever. They get the best players because they are right in the backyard of so many good recruits and they fill huge stadiums every weekend, they pay their coaches the most money so presumably they have the best staffs, they have the largest budgets, football is easily the number one sport in the region, etc etc etc. Of course it's going to be the best league, how could they not? And it's honestly not all that close. The top half of the Big 10 is certainly on par but the bottom half is a good ways behind the bottom half of the SEC. Do they win all their games? Of course not. Do they have some teams that end up just not being very good? Yes.
LSU, Florida, Auburn and Arkansas went 6-18 in the SEC last year. Those are 3 programs with some pretty damn good history and resources, all of which have won national championships in recent history. Mississippi State isn't a terrible team and is 2-22 in the past three years. Even Arkansas, they start the year with two blowouts over cupcakes, lose by less than a FG at Ole Miss, then lose at 8-4 Memphis by a point, and end up 0-8 in the SEC. If you slip up a little in that league, you are dead.
