There is only one compelling reason for Notre Dame to join the ACC, and ESPN has just spelled it out having completed an analysis of which conference would be good and positive for Notre Dame--ACC. The analysis which remains up on ESPN today (and link below) under Notre Dame--has the ACC today but gives ability to go back to previous conferences. There is no reason whatsoever for Notre Dame to go to the Big 12; not a good reason to B1G; and only hope the BE stays together. So as a conference, the ACC is it. Question should not be if but when...and now may be the time the pressue gets applied.

Part of discussion that Notre Dame had with the ACC goes beyond the Orange Bowl (my source indicated). The reason nothing is coming out yet on the Orange Bowl part of the discussion
is the basis for having Notre Dame as partner in the Orange Bowl and what the ACC expects. Although the ACC did not push the boundary; the ACC must protect itself from expansion out.
For example, has ACC indicated that it may go to 16 teams, wants Notre Dame to be one of the final two; perhaps offered Notre Dame opportunity to say which teams it would like as #16...etc etc...and a time frame to come back...or else the bloom is off the conference availability for Notre Dame...whence Notre Dame goes from here? It is now a
game of "chicken" and the risk-reward is very high. What you hear on the agreement between the ACC and Notre Dame on the Orange Bowl is going to be very telling as to what these entities may do around 2015.
