AAU membership is a huge roadblock for UConn to Big 10. Some will say Nebraska is not in the AAU and they are in the Big 10, but they were in the AAU when the Big 10 accepted them and, before Nebraska, no school had been EVER voted out of the AAU, so Big 10 had no reason to think Nebraska would or could be voted out. The reasons Nebraska got voted out were largely technical, so I can see them returning to the AAU in the future.
Here are some facts:
1. The head of the CIC and former President of Wisconsin was quoted as saying she'd be lying if the AAU or academics were a consideration when Nebraska was added.
2. The committee that ousted Nebraska was headed by a Big10 president and other Big10 presidents provided the crucial votes to oust them.
3. The committee was scheduled to vote on Nebraska's ouster PRIOR to Nebraska joining the Big10, but the vote was delayed (even the Nebraska President thinks this was done because the committee as was constituted a year ago did not have the votes to oust Nebraska). So, Big10 presidents delayed the vote until the NEW committee met 9 months later with enough NEW votes to oust them.
4. Nebraska's reasons for being ousted were not technical at all. Their research funding is far behind a good number of universities. And even if you count the agricultural research grants (which you shouldn't, because those are political pork, not reviewed) they are still very very far behind.
5. Notre Dame is not AAU and the Big10 has invited them in.
6. I'm sure UConn is trying to get in, but since research grants are way down in the current economic climate, you can't expect any new members whatsoever. The AAU is not an academic organization. It's a lobbying group that tries to push for an increase in gov't research funding.
