According to ESPN radio host Colin Cowherd he said that Utah and Colorado is a done deal to join the Pac-10. I expect a lot of expansion gossip to happen including U Conn to the Big 10 with the BCS meetings starting today. Not sure who Cowheard's source is, but unless the Pac-10 is doing the complete opposite of the Big 10 then Larry Scott of the Pac-10 is doing a good job of keeping it very quiet. It is known that the only two candidates that fit the Pac-10 academically is Utah and Colorado.
I'll try to grab the audio about this and post later today or tomorrow.
