...but you have to expand the field.
At least 8 teams...5 conf champs get auto-bids and 3-at large.
Why is this so difficult for people to grasp.
And you can leave it up to the conferences how the 'conf champ' is determined.
The 'must have' conference championship games maybe aren't how a conference wants to determine its champion.
The conference championship games are only for money.
