We literally just witnessed fake social media messaging cause lunatics to try to overthrow the government of the United States after the last national election--yet people like you are still trying to pretend social media has no influence?!?! in what universe exactly?
Texas and Oklahoma could have left any day of the week. Could have left any year. Just a few years back OU was trying to get the conference to expand and add a conference network. And social media trolls came in, proclaimed no value, don't associate with this or that school, BIG 12 doesn't need to do anything--if you do anything OU/UT will leave. People such as yourself were all too eager to jump on the train and promote the ideas that the BIG 12 couldn't, shouldn't do anything, no schools have any value-and bash anyone that thought differently--and now the results are clear--absolute disaster.
The only thing that made the BIG 12 "unstable" is people coming onto every message board for years on end proclaiming it was unstable while they convinced the fanbases--and through the fanbases, the leadership of OU and Texas that they should be with someone else.
Now, Arkansas, Missouri, Mississippi, Mississippi State, South Carolina, Kentucky, Vanderbilt and others will reap the rewards of the value of those schools. You'll never see them supporting that Alabama could do better i.e. in the Big Ten or something like that.
And to top it off, now trolls are coming in to try to stear WVU et al into the G5 at G5 wages and tell fans which schools to associate with or not. Just sad how the sheep follow.
