All 10 FBS conferences now have championship games, with the Sun Belt joining the fray this year as the last to adopt the format. Out of those 10 games, only the Big 12 title game does not pit division winners against each other.

Four of the 10 games feature double-digit favorites, and the four most competitive spreads are all in Group of 5 leagues. Six games are played at neutral sites, while four are hosted at campus sites. Only one game is a rematch of last year's conference championship game, and only one (besides the new Sun Belt game) features two conference title game debutants.
