That's exactly the point. If USC intends to play ND in 2027, why aren't the Irish on the schedule right now? They had plenty of time to schedule UNLV and Nevada. Why not ND too? Especially amid all of the current controversy and doubt. As I said previously, USC has dropped ND from its schedule. You domers just haven't figured it out yet.
And please don't worry about Purdue. Purdue is not only a charter member of the Big Ten, it is the founding member. Actually, Purdue President James Smart invented college athletic conferences in 1895. There were none at that time and he started the first one:
"On January 11, 1895 he (Smart) organized a gathering of the presidents of seven Midwestern universities (Purdue, Michigan, Northwestern, Illinois, Minnesota, Wisconsin, and Chicago) with the purpose of cracking down on many of the improprieties happening in football at the time. It was a monumental step, as the idea of an organized conference of collegiate athletics was almost laughable. Even the closely associated Ivy League did not form a formal conference until 1954."
"On February 8, 1896, one faculty member from each of those seven universities met at the same Palmer House (in Chicago) and officially established the mechanics of the "Intercollegiate Conference of Faculty Representatives" or "Western Conference."
