As of right now you have 6 major bowls
Rose Bowl
Sugar Bowl
Cotten Bowl
Peach Bowl
Orange Bowl
Fiesta Bowl
8 teams
First 4 bowl (could be any of them no specifics) on week after the Navy and Army week. Also, it'll be considered as the quarterfinals
Than the Semifinals will be on New years day like every year.
Then the National title will go to the highest bidder venue.
8 teams give every big sponsor and venue every year. No less or No more. It's the best scenario. Like Hokdawg said Conference Champs with 3 at-large bids perfect. Football does not need to be basketball or should never be a basketball playoff system.
