...If you look at it, there are only 3 conferences that have any sense of geography left: Big Ten, MAC, SEC. The rest are just a travel disaster....
Well, the MAC doesn't make as much sense as it used to, with U.Mass in the mix. That makes it comparable to several other conferences that are most regional, but have one or two teams that don't fit. The ACC isn't bad, but BC doesn't fit the geographical profile. The Big Twelve is the same, with WV not fitting. The Sunbelt isn't bad, either, but the two Florida schools aren't really in the footprint.
I'd call it this way:
Geographically reasonable - SEC, Big 10
Mostly reasonable - ACC (BC), Big 12 (WV), Sunbelt (FAU,FIU), MAC (U.Mass)
Just a big area, not much you can do about it - PAC 12
Make no sense - Big East, CUSA, MWC
