What would conferences look like if travel costs dictated what teams played each other? It might look a lot like conferences of old.

I struggled with where to put South Carolina, Maryland, Cincinnati, West Virginia, and a few others. You can rearrange these teams however you like. All that matters is we have thirteen conferences with ten teams each. Everyone plays a nine game conference schedule plus a home game versus a FCS team. Make it a 10 game schedule or keep it at 12 and allow for two non-conference games. That doesn't really matter.
There would be no conference championship game. The first place team in the seven major conferences would make the playoffs plus one at large team. Instead of conference championship games, the six champions from the "Group of Six" conferences would play six of the eight playoff teams, with the top two teams getting a bye. The higher ranked team would host the play in game.
For example, say Alabama, Clemson, Texas, Miami, Ohio State, Oklahoma, and Oregon won their conference and Georgia was the at large. Let's say Alabama and Clemson get byes. The play in game (or first round game) format could be:
Texas vs. New Mexico
Georgia vs. Appalachian State
Oklahoma vs. Troy State
Oregon vs. Fresno State
Miami vs. UCF
Ohio State vs. Toledo
Alabama vs BYE
Clemson vs BYE
Ninety-Nine times out of 100, the team from the major conference will host this game. Since this game is replacing conference championship games, I would think its reasonable to let the "Group of Six" have this chance. The major conference team will treat it like a final home game; a warm up for the quarterfinal round. The smaller conference schools would treat it like their Super Bowl, but who doesn't like Cinderella?
