I completely agree with Liberty and BYU needing to join conferences to remain relevant, especially Liberty. And I know ND wants to hold on the their independent status, but it seems that they would be in a better place if they were in a conference.
If they were in a conference then they could get into the playoffs if they win the conference or, for example, if they finished as conference runners up with a strong record as an at large (as a conference runner up they would also get an extra game against a strong opponent). ND in a conference gives them two avenues into the playoffs; ND as an independent has one avenue into the playoffs.
