College Football Playoff: The storylines to watch

Georgia is the defending national champion. It is playing in the Peach Bowl. The Bulldogs are riding a 15-game winning streak. They are heavy favorites to become the first repeat champion since Alabama in 2011-12. Ohio State is seeded fourth. The game will be played on New Year's Eve at Mercedes-Benz Stadium.

After 13 games, it's still hard to know what Ohio State is. The team was good, but it played down to the competition. It's loaded with talent, even if top receiver Jaxon Smith-Njigba and top running back TreVeyon Henderson are out for the season. They were 13th in scoring defense, second in points scored and features the nation's top quarterback (C.J. Stroud) in passing efficiency. Ohio state is a 6.5-point underdog against Georgia in the Bulldogs’ backyard.

Stetson Bennett is already a legend in Athens, Georgia. He led Georgia to its first title since 1980. Last season he was even better, posting career-highs in completion percentage (68.1%) and yards (3,425) and finishing fourth in the Heisman Trophy voting.

Jim Harbaugh has brought Michigan back to national relevance. There are vacancies in Denver, Indianapolis and Carolina. Last year, Harbaugh interviewed for the Vikings job, but he stayed at Michigan after getting a raise.

TCU was unranked in the preseason Associated Press poll and picked to finish seventh in Big 12. The Horned Frogs won their league title and are considered the worst team in their conference. They are a 7.5-point underdog to Michigan in Fiesta Bowl.
