Yeah I'm a fan of the 3+6/6 model. Each team has 3 permanent "rivals" and then plays 6 more teams for 2 years, and then alternates to the other 6 for 2 years. Or those 6-6 could alternate EVERY year but either way, you're playing every team in the conference at least 2 years out of every 4, and getting one home and one away game with them.
It's not a pod system because they're not all forced to play one another. For example, LSU's 3 rivals could be A&M, Ole Miss, and Alabama, but A&M could have LSU, Texas, and Kentucky, and Texas could have A&M, OU, and Arkansas, while OU could have Texas, Arkansas, and Mizzou. Mix and match however you like but the general idea is you play 3 teams every year, but you're not stuck in a pod with those 3 teams.
