There really aren't any (sorry BYU) premium teams/markets left for the picking in the non P5 world. So the next step is to pillage each other. The SEC and Big10 learned this and know what they are doing.
The B12 needs to wake up and realize somebody might start stealing the rest of their teams. And it may not be Texas or OU they are after. Teams like Kansas, K-State, Ok. State, and Baylor do have value in football and basketball. Other conferences could go after them just to start the implosion process which would be to their benefit.
If those teams were snatched up, the B12 would have slim pickings for replacements. Future tv revenue would go down the toilet.
