Florida State entered the game No. 3 with Miami at No. 7. Voters in the coaches poll and Harris poll took notice, giving coach Jimbo Fisher's team a boost in two components of the BCS equation.
Neither Alabama nor Oregon played in Week 10. However, both teams will be tested by Top 25 opponents this week.
Thursday, Oregon takes on No. 5 Stanford. Saturday, Alabama meets No. 13 LSU. The following week the Tide meet No. 9 Auburn.
Florida State doesn't have another ranked opponent on its schedule until a possible rematch against the Hurricanes for the ACC Championship.
The Seminoles' lead is thin and their stay at No. 2 could be short again. An Oregon victory over Stanford would likely to push the Ducks back into second.
Florida State (.9525 BCS average) is third in both the USA Today coaches' poll and Harris poll, and No. 1 in the computer ratings.
Oregon is second in the polls and third in the computers.
Alabama is first in the polls by a hefty margin and second in the computers with five weeks left in the regular season. The Crimson Tide remains on course for a fourth trip to the BCS title game in five seasons. Alabama was won three of the past four national championships, including the past two.
Unbeaten Ohio State is fourth in the standings, followed by Stanford and unbeaten Baylor. The rest of the top 10 is Clemson, Missouri, Auburn and Oklahoma.
Baylor plays host to Oklahoma on Thursday night, in the other huge game.
Of the potential BCS busters, teams from non-automatic qualifying conferences looking to earn an automatic bid, Fresno State from the Mountain West is in 16th place and Northern Illinois from the Mid-American Conference is 18th. Both the Bulldogs and Huskies are unbeaten. The highest-rated team from the non-AQ conferences earns an automatic bid by finishing in the top 12 of the final BCS standings or by finishing in the top 16 ahead of a champion from an automatic qualifying conference.
Louisville (20th) and Central Florida (21st) are the highest-ranked teams from the American Athletic Conference, which gets an automatic bid.
