Big 12 presidents say there's no rush to make decision on expanding conference. The presidents are hearing from two consultants, Navigate Research and Bevilacqua Helfant Ventures, that the Big 12 hired to assess expanded league models. The Big 12 is also considering forming its own television network and adding a conference championship game. Boren said it would be "wrong" for league presidents to view expansion as the only method for solidifying the conference's future.
