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

Mine is in the early 90s, but it's tough, because my idea structure never actually existed. 
Ideally, I'd prefer the old SWC, old 10-team SEC, but with FSU in the ACC and ND and Penn State as the major independents.  Miami in the Big East (they didn't play a full conf schedule until 1993, I believe).

Nailed it, except for that I'd add some set scheduling procedures for the SEC, instead of teams scheduling whoever they feel like from wherever they feel like, while acting like being in a conference meant something.  

Imagine a Big 12, without Baylor.

For this exercise, I don't want the B12, I actually want the SWC from the 80s.

Without Baylor would be nice.

Then it's an 8- team league, just like the Big 8 was at the time.  Worked out just fine.

9 conference games, 3 ooc games.  No CCG.

Perfection.

13 is better than 12.

Now you're just arguing to argue.

It would be interesting to collect opinions from CFB fans back in 1992 to see what they thought they wanted.

I'm pretty sure a playoff would have been on that card. 

never been a lack of fools

Oh wait, just saw OAM was opting for expanded SEC.

I'd prefer the year prior with Arkansas still in the SWC, that was a better alignment IMO.

I liked the Big Ten prior to adding PSU. That said, I think they were a strong add. And once they were added and the conference became odd-numbered and imbalanced, I felt like Nebraska was a good fit athletically and culturally [if not academically], and also balanced the East with the West. And 12 made room for a CCG, which I don't need, but I don't absolutely hate. 

So I'd be fine with the 10 schools prior to adding, or the 12 schools post. Anything beyond 12 it ceases to feel like a unified conference, and the post-12 additions don't "fit" very well with the Big Ten's historic identity. 

However, the bigger structure is that I want the postseason to go back to pre-BCS. Ideally even before the Bowl Alliance or Bowl Coalition. 

So either 10 or 12 teams in the conference is fine, paired with 1997 (or 1991) bowl alignment.
