It looks like BC and Pitt will play ND every third year, as will the other 12. Albeit, they may assume preferred status by playing in the first year, similar to the NFL scheduling old rivals (Ariz-Dall, Denv-Sea) in the first year after the 2002 realignment.
The ACC and Notre Dame announced the schedule matching the Irish and its ACC opponents for the 2014 through 2016 seasons.
The games are part of an agreement for Notre Dame to play five ACC teams each year in football.
Because of previous commitments for 2014, Notre Dame will face four ACC teams this season, then will play six in 2015 and five, starting in 2016.http://www.journalnow.com/sports/colleges/football/article_452dfefc-f9dc-5451-99c6-34d019251788.html
