If the sec went to 9 conference games who would be LSU secondary cross division rival

Who is our primary?

By rival, do you mean permanent cross-division opponent?

Alabama would tell the SEC what to do. Bama would get Vandy. LSU would get Georgia.

We’d have to play Florida, Georgia, and Alabama twice in the regular season. Then possibly again in the playoff

A 9-game SEC schedule would include two rotating East opponents instead of the one we have now (along with Florida as a permanent), like it was before 2012. But to answer your question, if a second permanent East opponent were put in place, my guess would be Kentucky, since we used to play them every year.

What I would do is home and home with Georgia and south Carolina or Kentucky and just rotate the other 4 teams

I’d like to see us play every SEC team within a 4 year span. I don’t care how, just make it happen.
