4 pods

West: BYU, Texas Tech, Oklahoma St
South: Baylor, TCU, Houston
North: Iowa St, Kansas, Kansas St
East: Cincy, UCF, West Virginia

Every team has 3 OOC games and then 8 scheduled conference games, playing their pod and 2 of the 3 other pods (with the missed pod rotating each year).

Then for the last game of the year, the teams in each pod are ranked 1 through 3 and match up with the same rank in the pod they didn't play.

So if the teams finished in the order listed above you'd end up with the 9th conference game being (assuming West/East and North/South were opposite in this season)

West #1 BYU vs East #1 Cincy
South #1 Baylor vs North #1 Iowa St

West #2 Ok St vs East #2 UCF
South #2 Houston vs North #2 Kansas

West #3 Texas Tech vs East #3 WVU
South #3 TCU vs North #3 Kansas St

This would allow for a mini-playoff among #1 seeds to go to the CCG and would ensure that whoever wins the conference finishes very strong for higher seeding.  It would also be useful for the 3 seeds, since those would be the teams mostly fighting for bowl eligibility and they would get an extra "easier" game against one another.

Until Texas and Oklahoma leave, you just go with 2 divisions. Add Oklahoma to the West/North pods for one division of 7, and add Texas to the South/East pods for the other division
