(AP) — For this college football season, the BCS probably would have been fine.

Two days after the College Football Playoff announced it is expanding to 12 teams, the field of four to determine this season’s national champion included two schools that did not even win their conferences.

Georgia, Michigan, TCU and Ohio State were selected Sunday for the playoff, giving the Big Ten multiple programs in the four-team field for the first time.

The top-ranked and reigning champion Bulldogs (13-0) and fourth-seeded Buckeyes (11-1) will meet Dec. 31 at the Peach Bowl in Atlanta. Ohio State got a reprieve, moving back into the top four after losing to Big Ten rival Michigan just a week ago.

“How we got here, at this point, I guess doesn’t really matter now that we’re here,” Ohio State Ryan Day said.

The second-seeded Wolverines (13-0) and third-ranked Horned Frogs (12-1) will play at the Fiesta Bowl in Glendale, Arizona, in the first game of the New Year’s Eve doubleheader.

The Horned Frogs were third coming into the weekend, but had to sweat out their spot Saturday night after losing the Big 12 title game to Kansas State in overtime.

“I was really nervous,” TCU quarterback Max Duggan said about watching ESPN’s slow rollout of the pairings Sunday afternoon.

The Frogs had nothing to fear. They had already built enough equity to stay in the top four, and they erupted with cheers of relief at their watch party in Fort Worth, Texas, when it became official.
