Even though Oregon rose to the No. 1 spot in all the major polls, the Ducks are No. 2 in this week's BCS standings.
Kansas State rose from second to first in the BCS standings released Sunday night, thanks to Alabama's loss to Texas A&M.
Perhaps more of a concern for the Ducks is that Notre Dame, which is third in the BCS this week, is not far behind the Ducks.
The Irish are ranked first by the BCS computers, while Oregon is only No. 4 in that category, and that has pushed Notre Dame within striking distance of Oregon, which has an overall BCS average of .9497 compared with Notre Dame's .9396.
All three unbeaten teams have a sizable lead over No. 4 Alabama, which was knocked out of the top spot by virtue of its loss.
The teams are merely interested in finishing in the top two, because those two will meet in the national championship game. Oregon has a clear advantage in the polls, with the Ducks ranked first in both the USA Today and Harris polls - the two polls used in the BCS ranking formula. But the computer are holding the Ducks back.
That is likely to change if all three teams stay unbeaten, however, as Oregon's remaining schedule is more challenging than that of K-State and Notre Dame. Oregon has games left against No. 13 Stanford and No. 16 Oregon State and a possible Pac-12 title game against No. 17 UCLA or No. 18 USC.
Kansas State has one ranked opponent left - No. 15 Texas - and Notre Dame's toughest remaining game is against USC.
