Perhaps the BEST B1G Forum anywhere, here at College Football Fan Site, CFB51!!!

the PAC isn't a good CFB partner and has the same problem as the Big 12

better to approach programs that add value

perhaps Mizzou, Kansas, Notre Dame, and/or UNC

Not going to pry Mizzou out of the SEC, and depending how strong the ACC GoR is, may not be able to get UNC. 

There are teams of value in the PAC. But as @TamrielsKeeper suggests, it's hard to just pick and choose. You can't just take USC and Washington, for example, because now you've got two severe outliers that have nothing in common with the rest of the conference and they're way out of the footprint. If you're going to blow up the footprint and take someone out west, you have to go all out.

That may not be necessary though... There are smaller moves that could make sense. It all depends how much you want to blow up college football all at once.

If you can't get ND, perhaps taking Kansas and ripping Colorado out of the PAC? UC-Boulder might be a good fit and they're narrowly on the same side of the Rockies as the rest of our conference. They're not a college football powerhouse, but it's a great school in a populous [and quickly growing] state. I think they'd be willing to consider leaving--the B1G can offer more money and I'm not sure they're any better of a cultural fit out West as in the B1G.

think B1G, take UNC and Clemson

Precisely, an expansion to 20 would be borderline required for any expansion from the P12 to really function in a way that you end up competing for national titles as a conference against the SEC.

I think USC/UCLA/Oregon/Washington are clearly the four most valuable, I'm not sure who #5 is from an athletic standpoint.  From a research grant standpoint probably Cal or Stanford.

I think we're looking at a conference that is really two conferences with some links.

Is UCLA in lockstep with Cal? That could be the answer right there. But, would Cal want to leave Stanford behind?

Of the schools you list, only Oregon is not an AAU member, but I don't think that matters anymore.

Chicago already pulled out of the CIC, so their input and insistence on only AAU members in that group is gone.

No idea on the politics of the Cali schools, but Oregon is listed on the AAU website as a member?

I get it probably doesn't matter, but might make it more palatable to the university presidents.

While CFB drives the bus, other sports can contribute a good bit, MBB.

I'm still all astonishment this is more than a rumor apparently.

Could the Big 12 survive by poaching the Arizona teams and Colorado (back)?

Throw in Cincinnati?

Colorado left for a reason, what makes you think they would have any interest in going back?  Maybe they would be intrigued by the idea of being the big fish in a small pond but that doesn't make much sense from a revenue perspective.
