On the P5 forum, I floated an idea which was triggered by the suggestion that the PAC may be more open to change than previously suspected. Because that idea affects some teams not now in the P5, I thought I would float it here as well.
Essentially, the Big 12 - often thought to be in its death throes - would remain intact in my proposal. Instead of the Texhoma schools moving west to the PAC, as some have suggested, I propose that the 4 California schools plus Washington and Oregon move east to the B12. That would bring the B12 to 16 members, and quell talk of megaconferences of 18, 20 or even more.
The remaining 6 PAC members would rebuild by adding Boise State, San Diego State and Fresno State from the MWC plus independent BYU. These schools could never have hoped to be invited to the current PAC largely because of resistance from the California schools. Fresno isn't a critical add here, but it would add a second school in the behemoth that is the state of California to help recruiting. This new PAC, which I presume would still legally own the PACN, would sell that albatross to the B12 which could make it very profitable where the PAC never could.
A 7th bowl would be added to the New Year's Six, allowing for both the new PAC plus the AAC to get autobids. Now, we can redesignate the six autobid conferences as the NY6 instead of the P6, and that's how I will refer to them.
At this point, there really aren't any more truly viable expansion candidates for the SEC, ACC and B1G, bringing some long term stability to the realignment process.
At 81 schools, the new NY6 would have produced more than 99% of all the appearances in the BCS/CFP top 14 (7 NY bowls X 2 teams) rankings over the past 15 years. No team outside the NY6 would have been ranked in the top 8 during that period. By every metric, the remaining four FBS conferences lag far behind the NY6, eliminating any reasonable complaints about exclusion from "the club".
The only downside I see is that it could kill the CR board, forcing us all to find something else to talk about.
