Again I have no insight as to what conversations are happening internally with the PAC12 only some details as to what the alliance consists of. I have no idea of what a scheduling plan would look like or even if the schools would all agree to it. The PAC could very well add some big8 schools but if it were obvious that those schools would increase the media payouts it would have already happened. The alliance is to keep the Big Ten from stealing USC and Oregon and to provide political power in setting up the terms for a new playoff and keep ESPN from consolidating their power. Its possible that grabbing some schools from the Big8 would be allowed but I haven't heard anything from the big ten side that says that is happening. If it did I imagine the Big8 schools would be getting a far smaller media cut then the rest of the schools but that is just speculation on my part.
Your funny, you say if the Pac was going to add someone they would have done it already, but at the same time say the B1G is going to add Pac Schools. Wouldn't the same thing have to be said, if the B1G was going to add Pac schools they would have done it already.
Fact of the matter is, no way this is true. There are way to many things in motion right now and too many things to figure out to get it done in a week or two. And saying hey we are going to just jump at a decision without actually discussing and and figuring out all the data, is just plain ignorant.
The same thing with all the posts that said that KU and ISU made a run at the B1G in the first few days and were shot down, No way anyone is making those kind of decisions in the first few days. While there may have been conversations no decisions were ever made that early.
My guess is no one outside a very small circle know what is really going on, or being discussed in any of these conferences and schools. And some of the initial ideas are just starting to be planned now. If the PAC says they are a couple weeks away from a decision, I would guess they will have who they want decided at that point, whether they offer right away if they do decide to offer will see.
I could see their "decision" could coincide with an announcement of the alliance. Meaning they announce the alliance and to or not to expand to strengthen etc the alliance at the same time. Same for the other conferences, in similar fashion.
Your sources probably tell you what you want to hear, the same non info that is all over fan boards and social media, just to appease you. Whether they have actual inside info or not. Sorry but no one is giving real info to just blab on boards to make him sound important. If they did information would be all over everywhere, this stuff is just kept too close to the chest for that.
