Blueblood means very little in today's CF when it comes to making money and survival. It's about eyeballs and the huge TV revenue. Kinf of like "what have you done lately."
Start with NYC, Chicago, Philadelphia, Pittsburgh, Cincinnati, D.C, Baltimore, Detroit, Milwaukee, Columbus, Cleveland, Indianapolis, Minneapolis, Los Angelas, and I know I've left out a few more. Those are all multi-million markets. Now they're eyeballing Seattle and Portland. Huge money for the conference members. Now look at the markets and money if Nebraska was still in the Big 12 or whatever it is now, Like night and day
BTW, it's being reported on 247 Sports that Nebraska has taken the lead in the B1G in bringing Oregon and Washington aboard which makes sense since NU will probably be more in line with developing rivalries (and travel considerations) - going forward - with those schools
With all of that said, I fully expect ND to be in the B1G within the next 2 to 3 years. Just don't see any way around it money and survival wise
