Everyone knows the biggest prize in the Big 12 is OU, Tx & KS. I don't see the PAC 12 winning the competition for those schools. I definitely see the B1G & SEC as the leader for those schools and I think even the ACC edges out the PAC 12. So if that leaves the PAC with a Nevada school, New Mexico, Hawaii or Houston, why not consider 6 or even 8 Big 12 schools to try and lock in the big prizes and add some content in CST?

With 6 schools they could take Texas, TT, OU, OSU, KS & ISU.
or if they went with 8 schools add KSU & TCU.

The only reason I could see the PAC thinking there is any other quality expansion is if they thought eventually the SEC & ACC merge and the B1G & PAC eventually do.
