Because the fodder is already baked into the conference. If what you're saying were true then why haven't they already given Indiana/NW/Vandy/etc. the boot? The B1G just signed the biggest media deal in history with equal revenue sharing through 2030. Their pieces of the pie would've been a lot bigger if they'd just booted the bottomdwellers. They didn't. Not only didn't they kick them all out, they kept them in with an equal share, through the rest of this decade.
And if you don't believe tOSU or Texas believe they need Indiana or Vandy and are only interested in marquis opponents, why do they all pad their OOC schedules with cupcakes? Why aren't we seeing tOSU v. Georgia, Alabama v. Michigan, Texas v. Oregon up and down all of their OOC schedules?
Sorry, I just think this is something that you hope will happen. But there's zero indication that it will.
