UVA: Charlottesville, is now a DC 'burb and also brings in the Richmond Market down to Williamsburgh, Portsmouth, Norfuck. Plus UVA grads are all over the country, much like Big Ten schools and unlike most ACC/SEC schools.
Definitely not. Way too far and no transport links, no interstate in an area where interstates go everywhere. Richmond will be a burb, if they ever execute the HSR plans (they won't, oil lobbyists own DC), before Charlottesville.
From DMV perspective, Charlottesville may as well be geographically in WV.
And that's part of the point of going down there for UVA and UNC. Maryland brings in the DMV but not an inch farther. VMI isn't the State Flagship, UVA is. It's a large school with a ton of alum that will pay even when they're 3-9. That's what makes a stable conference member; not flash-in-the-pans like Baylor or TCU that may occasionally be highly competitive, but have a very very low floor (if they suck, the coffers are empty) and easily saturate their ceiling (even if they're undefeated, there's only so many Baylor alum).
You didn't bring up Miami, but others have. They can't even fill the stadium when they're above average.
Corn has frequently been worse than Rutgers and Maryland since joining; yet still fill out their stadium, still draw eyeballs to games, still get their massive alum base to spend in various forms.
When looking for quality additions, consider what these schools potential are when they suck. Not when they're competitive. Because most schools will suck most years... only 10% can be in the top 10%.
Don't look at their potential to drop Wisconsin or MSU out of the top 10%, look at what their revenue and ratings situations are the other 90% of the time.
UCLA has been invisible for most of my lifetime. But we know their alum will keep them in good standing, regardless of their on-field performance.
UVA and UNC fit in that same field. And they also belong academically (UNC cheating notwithstanding they're an outstanding public Uni), as Ord noted. AAU membership is a cultural touchstone for the conference.
