several Pac-12 schools. 4-6 with USC and UCLA being two of them. Colorado also would be included. And this is just me speculating, but I can't imagine UW, UO, ASU, Cal and Stanford wouldn't be included.

“4 to 6 PAC top brand PAC schools to Big Ten is the move everyone is working on. If it does succeed in a strange twist it will be USC, UCLA and Fox Sports doing the selecting for Warren & Big Ten Presidents. Colorado would most assuredly get a spot”

BTM:
“Fox Sports is playing heavy hand in next move. They want top PAC brands to move into Big Ten. If it doesn’t happen it won’t be because of Fox Sports. The money is there. Main hurdles are California state politics and Big Ten eastern schools balking at travel requirements.”

There's more details. But this is the gist of it.

The whole thing is a complete cluster****. If this would happen, between the XII and the Pac leftovers, there would be a bunch of quality schools left abandoned from the Mississippi to the Pacific.
