I am saying who knows... anything is possible these days.
I also am saying if they ever came to a super conference, and they had a separate national championship, I am sure there would be another championship for the others not in the super league. Similar to FCS having their own championship.
The other thing is, they still have to fill content spots on media partners. So there will still be B12 football on TV etc. It would not be that much different than today.
It will just be another league, just like we have NFL, FBS, FCS, they all have separate champs. So it would be NFL, SCL (super college league), FBS, FCS. Not plausible that it happens but definitely possible.
