Part of the originally rumored Pac-10 expansion to 12 teams (the other school being Colorado), the Utes would actually fit in very well with the new Pac-16.
The first incentive would be allowing the Pac-10 to add the fast-growing Salt Lake City media market. The market, which ranks 31st in the country, would be a nice addition to the Denver market and the potential markets that Texas and Texas Tech would bring.
The Utes are also very competitive in men's basketball in addition to football, with a surprisingly strong tradition of excellence in basketball, believe it or not.
They make a bit more geographical sense, providing a closer geographical rival for Colorado and not being too far away from the Arizona schools in addition to providing a little more geographical balance to the rumored SW division of the expanded Pac-10.
Honestly I feel the Utes are a more attractive option than A&M, and if the Pac-10 could grab the Utes along with UT, TTU, OU, and OKSU, I'd say go for it.
