If the B12 were to add teams from the ACC I like this order:

1) Notre Dame - a man can dream, right?
2) UNC - not happening because they are also a desired target by both the B10 and SEC

(realistic options)
3) FSU - if they can be a good partner
4) VT - normally have a good football team
5) Georgia Tech - I think they can be good again
6) Clemson - if they don't completely become irrelevant
7) Louisville

(teams that add stability)
8) Miami
9) Pitt
10) UVa
11) NC State
12) Duke - for bb

The rest of the ACC should then become a part of Conference USA (Syracuse, Wake Forest, and BC)
