UVA is big time academics. Hate to say it but definitely more recognized for academics than TCU.
Their football is usually mediocre, but they sell a lot of tickets for a small-enrollment undergraduate school.
It's a clone of the typical Big Ten institution in a state that the Big Ten doesn't currently have an institution: populous state's 'flagship' R1 school. It's a no-brainer for the Big Ten, which makes it appealing to the SEC as well, most likely.
Plus, they won't threaten Ohio State in football.
I think the no-brainer ACC schools will be UNC, UVa, Clemson, and FSU. The 'maybe' schools are NC State, Miami, Duke and Georgia Tech or Virginia Tech. The 'SOL' schools will be Wake, Pitt, Syracuse, BC, and Louisville.
I tend to think the Big Ten is only goin to want two of those, and the SEC at most four. That leaves the possibility of some enticing programs for an expanded Big 12 (assuming things with the Pac 12 go as we think they will sometime in the next 5 years or so). My (realistic) dream list would be: NC State, Miami, VT, and Pitt. I kind of doubt Miami is that realistic, frankly, and I'd be just as happy with Louisville.
