The only way the PAC deal would even look somewhat appealing is if Texas, OU, OSU and Tech were the four that formed a pod with the Zona schools.
Baylor and TCU can go hump somebody else's' leg...
So ya, there are a few ways to put the puzzle together and your idea would be fine but I don't think it's the best. Here's why:
1. The first time around the Big 12/Pac 10 union did not work because not all of the universities invited on the Big 12 side wanted to be a part of the PAC 10. I would say that Aggy really, really did not want it because the left coast does not jive with their fake army culture. Secondly, the second university not wanting to be involved with the left coast would have been OU. OU is more of a midwestern state than a southwestern state in terms of culture and I would argue that there are parts of Texas that are more midwestern than southwestern; however, Austin definitely leans southwestern. OU will never join the PAC. They will go SEC b4 PAC.
2. This is the biggest reason imo... recruiting. If OU and OkSU go to the B1G, it's a step down in recruiting exposure. They will have locked themselves out of playing football in Texas. The reason the Oklahoma teams have such great success in recruiting Texas is because they play here regularly so family members can drive to games within Texas and to OK. The greatest example of what the Oklahoma teams will be doing to themselves is Piggie. Need I say more?
3. The B1G western division is going to be the arm pit/black hole of college football. Take a gander at the teams:
Nebraska - Former blue blood but quickly fading into the abyss.
Iowa - Sometimes ok but meh...
Minnesota - What's their mascot again?
Indiana - See Kansas
Illinois - puke
Purdue - puke
Northwestern - puke
Do you ever envision planning a vacation around one of these road trips?
The B1G eastern div will be stellar but they already have their club and we wouldn't be in it... We would be the ones making the western div look better.
4. I stated the puzzle pieces earlier. If Texas, TTech, OkSU, and OU go Pac then where do TCU and Baylor go? They would clearly be prime prizes for any league because of their exposure to Texas recruiting. These schools are private Christian universities and would be an easy fit in the SEC. The SEC would snatch them up in a heartbeat. They would take them over KU and Kstate in a millisecond.
5. We need to button up Texas as much as possible. Keeping Texas, TTech, TCU, and Baylor together would be a home run long term. We keep some in state rivalries and have a pod / division that would be much more manageable. Our potential divisional foes would include AU, ASU, CU, and Utah... these teams are not a great draw for Texas kids so we keep more recruits in-state among the 4 Texas PAC schools. As a group we would get more pub than aggy and aggy would become more irrelevant over time.
****So, keep Texas teams together and push out B1G / SEC while limiting PAC exposure because of distance = a recipe for success. IT's all about recruiting and this will keep more Texas blue chips in state.
