I believe I heard during the ASU president interview with the press he mentioned that ASU had another option out in the East, which I assume it was the ACC.
If true, Yormark getting Colorado to join was the key, which provided better option for the other corner schools to join the B12 vs. the ACC. Had ACC offered Colorado from the start, things might look different today. Since B12 had the pro rata with the media companies while ACC didn't with ESPN, it made sense 3 corner schools went with the B12 for the sure thing vs. being in an unknown situation with the ACC.
ACC's lack of vision, and the fact it didn't have the pro rata media pre-negotiated, means they simply could not move as fast as the B12. ACC is just the ACC
Things start to make some sense from the B12 point of view if this is true. Let's hope we are 17th or 18th.
