Florida State (.9525 BCS average) is third in both the USA Today coaches' poll and Harris poll, though the Seminoles gained ground on the Ducks after a 41-14 victory against Miami on Saturday night. Florida State is No. 1 in the computer ratings.
Oregon is second in the polls and third in the computers.
