ND is a ACC member and when they can get more money as a member than as a nonmember they will join for football as well ... When the ACC network kicks in they might.... If the ACC put 2 into top level bowl (formerly BCS bowls + 2) on a regular basis and ND is not in a on of the top bowl they may join for football. ND is a member as far as bowl games are concerned except for the top bowls (THE 6) . If ND can get in a top bowl every year and the 4 team playoff on a consistent basis they likely will stay independent in football. The will not join another conference any time soon, the ACC holds the media rights for ND sports other than football and hockey.
