I believe the Pac-10 commissioner has already said they are not looking to expand any time soon. For my interpretation of that, it means not until 2015 will anything happen. Maybe by then BYU will have enough good seasons in football and basketball, that the Pac-10 will want to take BYU and Utah. Any other choices seem illogical. Nobody else comes close. Plus, it seams like each Pac-10 school is in it with its rival, OSU & Oregon, USC & UCLA, so you can't take BYU without Utah. They would dominate the Utah/Salt Lake media market if they took both schools.
