Some very interesting insight into the ND scheduling process and some specific mentions of when Clemson can and can't play ND. The video is shot after the regular season but before the bowls.
Looks pretty clear that, in the future, when Clemson plays ND, Clemson will host ND in odd numbred years (when Clemson travels to South Carolina) and will travel to ND in even numbered years (when Clemson hosts South Carolina).
I'm not a fan of the lack of equality in college athletics.
Whether it is Notre Dame's partial ACC affiliation, the Longhorn network, Tobacco Road's influence in the ACC, The University of Oregon's bank roll, or South Carolina's lobbying efforts in Columbia. It all comes down to who has more money or the right connections. (and therefore more power)
I suppose it's different if your team is the one with the advantage.
