I can't see ND joining a conference. The alums would go nuts.
Oh, I understand. They sure would got nuts. It'd be ugly, ... for about two whole weeks!
But young-to-middle aged ND alums are not as married to independence as the old guard. In fact, they are like almost all of us. They watch College Gameday. They play fantasy sports. They play video games (well, I don't). They like having something to play for during seasons in which they lose twice in their first 6 or 7 games. Which, BTW, is most seasons nowadays.
Remember, Notre Dame for 40+ years, eschewed all bowl invitations. That changed.
Remember, Notre Dame would not allow 5th-year players. That has changed in practice (if not title).
Remember, Notre Dame once played on a grass field. No longer.
Remember, Notre Dame once proudly made no academic concessions for football players. Lou Holtz changed that.
Remember, Notre Dame once distanced itself from Miami and Michigan. They've played Miami (even before the ACC agreement) and there is already talk/momentum about when the Michigan series will be revived.
Remember, Notre Dame was once a true independent. Now they play 5 games against the ACC annually.
Notre Dame is justifiably proud of its traditions, status and standing within the CFB community. They are currently a power broker.
But they are not as insular. They will change. They always have, just at a more deliberate pace than the rest of us.
Otherwise, if they don't change, those traditions ... that status ... their standing will erode over time. And they would not like that.
