One reason why this rumor makes sense is because of an irrational fear of a CCG knocking out a team. (yeah the Big 12 got burned before, but its just as likely to help a team that needs a win)
If the Big 12 can just play their 12 games, they are probably fine with selecting best 4 available and presuming they'll always have a 12-0, 11-1, or strong 10-2 team make it. If you force them to play a CCG, which again they are irrationally afraid of, it would make sense for them to respond by insisting on conference champs. Whether or not they ultimately cave on that demand is another story, but you can see why they would make the demand in that case.
So the Big 12 is vital, but the ACC doesn't even get consideration? Try again. ACC teams have won a lot more NCs in the past few decades than current Big 12 teams.
