re: Once the playoffs expand, what SEC teams will constantly be in?

Let's go by conference:

ACC - 2 at most: Conf Champ, maybe RU (Clem & FL St/MI, UNC/NC st)
B12 - 2 at most: Conf Champ, maybe RU (TCU/Bay/K-State)
Pac12 - 2: Champ and Runner-Up (USC, Oreg, Utah, Wash)
Big 10 - 2: Champ and Runner-Up (OH st, Mich, Penn, Wis(Fickle),N (Rhule))
G5/At Large - Only Highest ranked team if Top 15 (ND, Cinn, etc...)

So that's 9 BEFORE SEC
Leaving SEC to almost always have 3 - Champ, RU and 3rd best who missed Atlanta by 1/2 game(s)
I expect to see: AL, GA, with rotation of LSU,Tenn, Ole Miss as #3 then once/4 yrs FL, T&AM,K, Aub, Ms State
