WHAT'S AT STAKE

KEY MATCHUP

PLAYERS TO WATCH

Florida State: S Jalen Ramsey. The gifted sophomore could be the Seminoles' biggest difference-maker against Oregon's high-scoring offense. Along with his coverage and tackling skills, he has been effective lately on the blitz - which might be the only way to slow down Mariota.

Oregon: RB Royce Freeman. The Ducks' inexhaustible collection of talented tailbacks has another star in this freshman from Southern California who has been outstanding from his first game. He racked up 1,299 yards and 16 touchdowns for the Pac-12's top rushing offense, and the Rose Bowl could cement his place on the national stage.
