The P12 has made it quite clear they will explore expansion and that will happen when the OUT settlement is reached with the B12.
The only R8 expansion target for the ACC is WV, no geographic absurdity there. Also no geographic absurdity with the P12 adding 4, 6 or 7 of the R8.
Suggesting a Pac9 merger with the BIG is ludicrous on multiple counts including blowing up the Rose Bowl tie ins, the geographic absurdity associated with it and the political barriers of excluding non AAU flagships in AZ State, Oregon St and Wazzu.
And as pointed out repeatedly to you, if the B10 expands, it will be KU and ISU.
