From a UCLA fan site:
"Colorado to the Pacific 10? By no means is this out of the question. The Kansas City Star, in its recent series on the Big 12, considered the possible jump of the Buffaloes. Wrote Blair Kerkhoff: "Colorado, the only Big 12 school in another time zone, often looks West. Could it resist an overture from the Pac-10?" If Colorado headed West, it likely would do so with another team to maintain balance in the new conference and give the Buffaloes a travel partner. Although Air Force, Colorado State, Utah and Brigham Young are mentioned as candidates to join Colorado in the new league, the Utes and Cougars make the most sense to the Wiz. Now why would the Pac-10 even consider expansion? First, the conference could split into North and South divisions, with Colorado and its partner joining the Washington and Oregon schools in the North. This in turn would create a lucrative football title game without disturbing cherished league rivalries (Oregon-Oregon State, USC-UCLA, etc.). The second reason is that a beefed up Pac-10 -- with the addition of the Denver and Salt Lake City markets -- would be a television juggernaut. Consider this: outside of San Diego, Las Vegas and Albuquerque, the league would have every major TV market in the West."
