Notre Dame is obviously the big prize, although I would just as soon see them get left out and end up in a poor situation. It would be a fitting end to their arrogance.
Assuming that the Big Ten leadership is not as spiteful as I am, eventually, Notre Dame will be in the league. That would leave three more spots.
Delaney has been very clear that the Big Ten wants to move south. Texas would have fit the bill, but they are out of the picture. When you look at the members of the Association of American Universities, I believe that the Big Ten's next move will be to raid the ACC.
Georgia Tech, Maryland, North Carolina and Virginia would all be great geographic fits to extend the network south. If the conference could pull in two of those and then round out the 16 with Rutgers, you would have a great geographic presence in football territory and the academic profile the Big Ten is looking for.
As an aside, if the SEC where smart they would grab Cincinnati, Virginia Tech, Miami and TCU or Texas A&M. Their foot print would be an incredible coverage of the best college football states in the nation.
