Based on this data, Michigan's Great Lakes Conference was arguably the weakest last season - a case could also be made for the Ohio Valley and Gulf conferences. The Mid-Atlantic, NorthEast and SouthEast were the strongest.
I was curious if there is a built in bias towards BCS schools. The Mid Atlantic conference does have 11 BCS school out of the 12 (poor ECU) at the other end of the scale The Rio Grande and the Ohio Valley only have 4 BCS schools. The GL has a respectable 7 of 12 (counting Notre Dame).
I hope to follow these proposed conferences this season to see how they fair.
