Here's how that hypothetical pod system would likely play out:
Eastern Division
"Southwest" pod: Oklahoma, Oklahoma State, Texas, Texas Tech
"Mountain" pod: Arizona, Arizona State, Colorado, Utah
Western Division
"Coastal" pod: Cal, Stanford, USC, UCLA
"Northwest" pod: Oregon, Oregon State, Washington, Washington State
Don't know why people bring this up as something that is likely. A CCG is only allowable if the divisions play a round robin. It's a rule that makes sense and isn't going to be changed. It's even more ridiculous to suggest there will be a 2 round playoff to crown a conference champion. If the NCAA were to allow another week of play, it's going to be for a NCAA playoff, not to allow a conference to have 4 divisions of 4 teams for no good reason.
Pods might work for basketball, but that's because NCAA bids are not determined solely by being a conference champion so no one really cares about the conference tournament in the grand scheme of things.
