The Ducks and Tigers remained 1-2 in Sunday's latest release of the BCS standings, leaving no doubt they are the schools to beat in the title-game chase. Oregon remained on top with a BCS average of .9764, followed by Auburn at .9682.
Boise State, however, appears poised to take advantage if the Broncos win out and either of the top teams falter.
For the second straight, Boise State took a big bite out of Texas Christian's points lead in the all-important fight for third position.
TCU remains No. 3 in this week's standings with an average of .8995, with Boise State close behind at .8860.
Boise State was the only undefeated team to play this weekend, scoring an impressive 51-0 win over Fresno State on Friday night. The Broncos made up ground on TCU in all three BCS components.
Boise State, which jumped TCU in the polls last week, increased its advantage in the USA Today coaches' poll from 11 to 41 points and from eight to 62 points in Harris Interactive.
Boise State also moved up one spot, to No. 5, in the BCS computer average while TCU remained at No. 3.
It appears inevitable that Boise State, if it wins its last two games, will finish ahead of TCU because the Broncos have an impact game this week at BCS No. 19 Nevada (10-1). Boise State closes the season Dec. 4 at home against Utah State.
TCU has only one game left, against New Mexico, which fell to 1-10 after a Saturday loss to Brigham Young.
Finishing No. 3 in the BCS standings is important for two reasons: If Oregon and Auburn win out and play for the national title on Jan. 10 in Glendale, Ariz., the highest-rated team from a "non-automatic qualifying" conference will replace Oregon in the Rose Bowl.
If either Oregon or Auburn loses a game, the No. 3 team has a chance to earn a spot in the BCS title game.
Nebraska, which was No. 8 last week, dropped to No. 15 after a 9-6 road loss to Texas A&M.;
The BCS standings also might be used to determine this year's Big Ten representative to the Rose Bowl if there is a three-way tie among Wisconsin, Ohio State and Michigan State, which are all favored to win their final conference games.
In that case, the highest team in the final BCS standings will determine the Rose Bowl bid. Wisconsin currently holds the advantage in that scenario.
