Super dumb take by that writer. The basis for no expansion is largely that if the other leagues rescue the teams they would be "plundering" the Big 12, thus being predatory and contradictory to the "Big 12 matters" statement. Nobody, including the ACC or the Big 12 member institutions think the Big 12 as an entity matter. If all the schools got snatched up nobody is going to be saying, "man, those other conferences were predatory." Everybody would view an invite as a lifeline. Only teams left behind would view it negatively. What a stupid conclusion to draw.
And second, like the others, it's the typical "no value" argument. Again. If the team that would be third in your league in viewership would not add value, your league is as good as dead. Only a PAC homer would think they can stick with the status quo and not die.
You are correct it is complete "double speak". Of course it means the B12 institutions received something of value if they are all placed somewhere but that's not what the remaining leagues seem to want. Instead they are trying to diminish the B12.
Also, note two of those quotes are from the ACC & PAC commissioners not the writer.
I can't see how at the end of the week now the PAC will announce its moving forward with considering expansion.
