The AAU thing will only be used for schools that don't want UConn. Those same schools would probably overlook it for other schools. That's UConn's problem, that it doesn't have a sufficient football program to override those concerns. If you see the emails from PSU's, Northwestern's and Iowa's presidents to Nebraska's president(unsealed with a FOIA request) long before Nebraska joined the B1G, it was clear that everyone in the B1G knew that Nebraska was in the process of being ousted from the AAU (mainly by the Pres's of Michigan and Wisconsin) prior to joining the B1G. The former Pres. of Wisconsin, now Pres. of Amherst College, said that in the discussion of Nebraska's candidacy, she never once recalled anyone mentioning its AAU status.
Now, that is not to say that AAU status won't be a topline item with any other candidate because it could be that people avoided talking AAU when discussing Nebraska because they knew it was a minefield.
