The problem with an ACC look-in is that ESPN owns the entire AAC for the price of a single ACC team.
I think you've got the short term reality: Hope that the Big 12 either blows up or needs to expand.
I was thinking about that with regards to the ACC/AAC pay outs per team/whole league.
Hypothetically, by the time this look in would occur, say they grab UConn/WVU (as the Big12 GOR wouldn't be so many years out).
From there you'd have basically the combined Big East (football) and ACC - or what should've happened years ago.
Have all teams under the ACC umbrella from Boston to Miami ( aside from NJ).
I think fan interest and ratings will ultimately suffer as rivalries cease to exist or fade awaay.
Just highlight the rivalry games in both sports - no need for divisions two highest ranked teams play for the ACC CG and in basketball just play your rivals twice.
I've seen Michigan fans complaining about their home slate of Maryland, Penn state, Indiana and Minnesota and I imagine FSU wwon't be happy with a BC, Pitt type double dip, where as vs UConn/WVU those are bigger games.
Just my rambling thoughts tho..
