FWIW, Sagarin & Massey both agree SoCon sits well ahead of the Ivy League & just behind Conf USA.
Here's a breakdown:
Positions 1-6 filled by P5 & Big East
Positions 7-10 filled by American, Mtn West, West Coast, and A-10
Positions 11-13 filled by MVC, Conf USA, & SoCon
Positions 14 -(orders vary between Massey & Sagarin): Ivy, Colonial, Sun Belt, WAC, Big W, MAC, etc.
We can argue whether those in positions 7-10 are mid-majors or power conferences, but by the numbers SoCon looks impressive. Perhaps someone not as cheap as me, who's registered with KenPom, might confirm whether his conference rankings agree with those of Massey & Sagarin.
