Here's a thought:
Nebraska fled the Big 12 for the Big 10 in part because they were sick of being Texas's b****.
Well, if Texas joins the SEC, maybe Nebraska would rejoin the Big 12 (er... Big 8?) since the Texas problem would no longer factor.
We already know that Nebraska and its fans are unhappy in the Big 10 and have whined and complained.
A Big 12 without Texas and OU would see its TV payouts absolutely collapse.
ESPN and FOX would probably force that conference to take a 50%+ pay cut at some point (next contract or current contract if the grant of rights is invalidated).
Big 12 may not collapse entirely, but it's not a viable destination for Nebraska without Texas/OU.
Heck if Texas/OU leave, Nebraska is permanently a Big Ten member; can't ever really see a different conference that would work for them.
This honestly sounds like a worst case scenario for everyone else in CFB; SEC already markets themselves as if they're the NFL of college football; that'd probably be on steroids with Texas/OU.
Competitively, I don't get why SEC schools would want it. Alabama doesn't care, but the rest of them should care about wins and losses.
