I read somewhere that with 4 pods, the conference championship could be a Final 4 of the pod champs. I hadn't thought of that, but it would be awesome AND it's realistic, because it would mean more $$$.
.
To piggyback on that idea, maybe 10 years down the road, if/when there are 4 superconferences of 16 teams divided into 4 pods, you could have the national playoff be 16 teams - all pod champs.
The 1st round would be the conference semis, the quarterfinals would be conference championships, and then you have your final 4. It ends up very neat.
