In my opinion Virginia "wins" that spot. Large state flagship (Miami is a private University) better aligned with the majority of the league, strong academics (better than Miami's which are also strong); adds a new state market that is continuing to grow in population.
The a-tier of ACC schools is Clemson, Florida State, UNC and I think UVa is perceived on that level. Miami, NC State, Virginia Tech and Georgia Tech are the next tier. Duke is kind of its own space and everyone else (Cuse, BC, Pitt, Louisville, Wake) has no hope of moving.
