Would the Big Ten invite Syracuse even though they're not an AAU university? I know Notre Dame and Boston College aren't either but Kansas and Missouri are as is Rutgers.
Nor is Nebraska now.
But there status was recently revoked. They had been an AAU member since 1909 and had their status rescinded by just two votes. Plus, the Big Ten had already voted to accept Nebraska in as the 12th member before their AAU membership was taken away.
Big Ten commissioner Jim Delany, speaking at last year's spring meetings as expansion was heating up, had this to say about the Big Ten and its AAU ties: "AAU membership is a part of who we are. It’s an important part of who we are."
So I guess the Big Ten must be working on the papers right now to banish Nebraska out of the Big Ten. Course not. And I'm sure the Big Ten had no clue that for the past couple years, Nebraska has been threatened to be boosted from the AAU...decision to boot them did not happen overnight.
Because the pure academic factor is a non-factor. If the Big Ten were to expand to 16 as a reaction to other conferences expanding to 16, then it would be quite clear that AAU would not be the deciding factor, revenue would be. And last summer, Big Ten decided that only likely outgoing AAU member Nebraska was worth adding, not committed AAU schools like Rutgers, etc.
