Here's what the five remaining unbeaten teams need to do in order to reach the BCS championship game in Glendale, Ariz. (Teams are sorted by BCS standings.)
1. Oregon (8--0)
The Ducks will be heavily favored to beat Washington and Cal the next two weeks before two tough tests to end the season: Arizona at home and Oregon State away. If Oregon runs the table, it won't have to worry about being left out of the title picture.
2. Auburn (9--0)
Like Oregon, the Tigers will be in if they win. However, they face the most difficult road to perfection: Georgia on Nov. 13 and Alabama in Tuscaloosa on Nov. 26 in a de facto national title play-in game.
3. TCU (9--0)
Running back Ed Wesley (above) and TCU leapfrogged Boise State in the latest standings, making them the non-BCS team most likely to make the title game. Even if they win out, the Horned Frogs must hope for a stumble by at least one of the top two teams (Oregon would help them more), then get a lot of love from the poll voters and computers to fend off the one-loss programs.
4. Boise State (7--0)
To reach Glendale, the Broncos need a finish similar to the one in their shocking 2007 Fiesta Bowl upset of Oklahoma. Besides winning out, that would require at least missteps by Oregon and TCU and some favorable BCS math.
5. Utah (8--0)
