FGB---I've got lots of VERY mixed feelings about it. First off, just to address the "semantics" of their article, I can't see how they can call it a casualty of conference realignment, since ND never has been, and likely won't be (for my lifetime) in a conference.
But more to the point (about ND leaving the schedule after '14): I've wanted them replaced with another high-profile quality opponent for some time now. And I've always wanted them moved further down the schedule, say, to the last non-B1G opponent we played (the 4th week, rather than the 2nd, or even 1st)...which of course didn't happen.
Hell, we certainly have had some doozies with them lately (like the last 4 years), and it is exciting, but frankly, we've played them what, 30 times in the last 35 seasons? It's time for a change IMO. But it's also very important we don't replace them with another UConn or Akron. But rather, a home-and-home with an SEC school, then maybe one with a USC or Oregon or Stanford, then another SEC home-and-home, etc.
So I'm not really sad the "rivalry", such as it's ever been, is all but over.
