If we are to believe the story being presented, Texas and OU approached the Big Ten about joining. The Big Ten said OU isn’t an AAU school, so it’s a non-starter. If that is all true, then there is pretty good evidence that the Big Ten does not want non-AAU members regardless of their value considering they turned down two top ten brands that were going to come in a package deal.
Now, if they were smart, they would have declined anyway because Texas would immediately destabilize a conference that has Northwestern, Purdue, Rutgers, and Maryland in it.
