Protip: FSU is actually a higher ranked school in the 2013 US News and World Report rankings than Kansas. So do Oklahoma and fellow AAU member Iowa State.
KSU also gained a net ten spots this year on KU in said rankings.
There were rumors in the last round of AAU voting, when NU got kicked out and Syracuse resigned, that KU was in danger of losing the designation.
So, if the Big Ten really wants to get serious about academics, they'd invite UVA and GT, and they'd call it day.
