Really? You think Utah is too good for the Mountain West? That's your real problem, isn't it?
Sorry, the reason the Pac-10 is NOT expanding anytime soon, no matter what you may want to happen, isn't just to maintain the truthfulness of the "10" part, unlike the Big Eleven. Right now, the Pac is divided into five nice and neat geographic rivalries. Adding Utah and Boise State (the next logical football addition) wouldn't maintain that pattern.
And frankly, as much as I respect the mid-majors, I really think Utah, Boise State, or any other addition from the Mountain West or WAC would be Cal-Oregon-Oregon State-Arizona-State-on-a-good-day level in the Pac-10, not USC level. USC and the good SEC/Big 12 teams are perennially just that good. (Keep in mind, USC beat Utah 16-0 on the road in the Golden Bowl Octofinals.)
Quit worrying about the Pac-10's lack of respect and start worrying about your real problem - the Mountain West's lack of respect and its need to expand with Boise State and maybe Hawaii, Fresno State, or Nevada. Who knows, maybe someday the Pac-10 will be wowed with the prospect of conference championship money and bring on Utah and BYU (both fairly good teams in both football and basketball). But as some of the commenters on this opinion piece suggest, getting more appropriate bowl tie-ins and less reliance on FSN is probably going to have to come first.
