"Per Rittenberg, the Big Ten is only interested in adding schools from the Association of American Universities (AAU). Per the AAU’s website, the only Big 12 teams included in that group of schools are Iowa State and Kansas. Rittenberg also pointed out that the Big Ten would have interest in Pac-12 schools that are AAU members, such as California, Washington and others, and that Notre Dame, while not included, would be an exception to the requirement."
