Salt Lake (Utah, BYU) is a pretty big city, especially relative to Pullman, Eugene, and Corvallis. So is Denver (Colorado) or any of several California schools mentioned as possibilities.
The conference is also going to be big on academics/research. Every school in the Pac is a research institution in addition to academics. Cal/Stanford/UCLA/USC/and UW are either public ivies or very highly ranked private schools. They will have big issues with letting in, say, a Boise State. So any candidate would have to have both serious academic and research credentials.
Again, the Pac 10 already has a few schools that don’t rate well in that regard. Neither Oregon State or Washington State show up on “research university” rankings. Colorado and Utah do.
BYU is a no-go. Stirke One: Not a significant research institution. Strike Two: The big problem is that they won’t play sports on Sundays, and a lot of non-football sports (which the Pac-10 excels in and love) do. And the third strike is another biggie: the entire Mormon religious affiliation will rub the liberal (in both the classical and literal sense) schools the wrong way. Again, you just need one Pac-10 school saying no, and it’s not going to happen.
The only thing there that is even slightly relative is the Sunday issue. But the big sporst aren’t affected by that rule, and the various conferences that BYU has been part of have managed to deal with it. Sure, you can put it on the “downsides” list, but you are completely ignoring what BYU would bring into the conference, like its national following.
When you get down to it, there are only two or three schools that would barely make the cut, and the problem with those schools is that they’re not natural rivals on one another. Each Pac-10 school has its natural pair (UW/WSU, OU/OSU, Cal/Stanford, UCLA/USC, UA/ASU), and that’s going to rub traditionalists the wrong way.
Depends entirely on who gets brought in. Utah/BYU solves that problem nicely.
Finally, assuming you do find two schools, how you divide the conference is going to provoke a knife fight. Anyone who suggests a typical North/South split are idiots who don’t understand the West Coast. UW/Oregon/Oregon State/Washington State will vote no because that kind of split would cripple their presence and recruiting in Southern California, which has a larger population than Washington, Oregon, and Arizona. In other words: that’s where all the best talent is. Washington’s big recruiting class that was signed last week had 16 kids from California, most from SoCal. A North/South split would relegate the Pac-10 North into Big-12 North status, crippled from the main sources of talent and otherwise irrelevant.
That means an unorthodox split, which would be controversial. And everybody would be jockeying NOT to be in USC’s division. And, again, one school says no and it’s not happening, period.
It’s not like the divisions wouldn’t play each other. Right now Pac 10 football plays 9 conference games in a 12 game season. In a two division alignment, only 5 would be divisional games, meaning you could play 4/6 teams from the other division each year. Rotation would mean you’d only miss playing a given team in the other division maybe every other year. I don’t see that impacting recruiting as negatively as you seem to think.
The Pac-10 almost let Texas in, after the SEC formed up and sent Texas’ old conference into the dustbin. And Texas fits. Public ivy/massive research/huge TV audience. Stanford vetoed it and it was dead. So now you know why Pac-10 expansion is going to be a nightmare.
There are various reasons why Texas didn’t join the Pac 10 at that point. The big obvious one is that it isn’t a geographical fit. So it’s not a good example.
Under their previous commissioner the Pac 10 was extremely conservative. They made a choice to bring in someone with a different perspective and that means looking at all of this. There seems to be a serious willingness to look into moving to a “Pac 12,” even if that does mean thinking beyond the conservative viewpoints that have ruled the conference for the last 30 years.
