I think the AAU membership will always be a criteria due to the research funds the Big Ten Academic Alliance controls. The addition of AAU schools can only increase that funding and the research funding dwarfs what the athletic payouts are.Good point. The AAU aspect would be desirable but may no longer be the deciding factor for the B1G, however academic standing will probably still be a deciding factor.
when there is a move , IMHO Clemson would end up in the SEC
