It is ironic. The ACC's first response to this a year ago would have been to lock up the Big East, including ND, to play the ACC Champ in Miami. Having made the Big East less prestigious, the ACC now has to beg one of the big boys to do some deal -- any deal -- with it or look like total idiots.
This is also the first proof that the 4-team playoff deal is assumed to be a "done deal" by the big boys, because this deal kills off the BCS, and reduces money for the sport, otherwise (in that id devalues the Fiesta and Orange).
