Something interesting about the Big 12 and SEC that I just looked up...
So, let's say the Big 12 adds FSU, Clemson, GT, and Notre Dame. If you take the 2012 US News and World Report rankings, the average ranking of schools in the conferences would be...
Big 12: 96
SEC: 96
Both conferences, 14 members apiece, would have 4 AAU schools.
Honestly, we would be mirror images of each other. Almost exactly in every single way.
