Larry Scott was the one that moved the search to the Big 12. Prior to Larry Scott the Pac was more interested in travel partners than tv markets. So its definitely possible.
There is no info in the media regarding pre-Larry Scott expansion, so the posters that are saying nothing was reported about it are only half right. Reporting on the Larry Scott expansion efforts would not include this info.
Thanks for sharing your info and I think I am going to buy your book for my uncle who is a huge Rose Bowl fan
