Made me think of a weekly lottery.
For OOC games, all 130 or whatever teams have a ball bouncing around in the bubble, and on Tuesday, you see who you're paired up with. They'd televise it and everyone would watch.
Clemson vs New Mexico, Ohio State vs Georgia, Texas vs Texas A&M, etc. Random...maybe good, maybe weak.
Then you'd do it for each conference, the same way. You already played someone, they're removed for your turn.
