After Alabama lost at home to Texas A&M on Saturday, Oregon climbed to No. 1 in both the AP and the coaches' poll, the latter poll counting in the BCS standings.
The Ducks are also expected to be No. 1 in the Harris Poll, which will be released later today.
The top three in both polls is the same: Oregon, Kansas State and Notre Dame, the three remaining unbeaten teams. Alabama is No. 4 and Georgia No. 5 in the AP poll, but their order is reversed in the coaches' poll.
Oregon was an overwhelming No. 1 in both polls, earning 45 of 60 No. 1 votes in the AP and 44 of 59 with the coaches. Kansas State got 14 No. 1 votes in both polls, and Notre Dame got one No. 1 vote in both polls.
While Oregon is in control in the polls, it still is projected to be behind Kansas State in the BCS standings, which will be released tonight. The Wildcats are ranked higher by the computers, which make up 1/3 of the BCS formula.
Oregon's computer ranking should go up substantially over the next three weeks, as it plays ranked teams Stanford and Oregon State the next two weekends before playing a presumably ranked team in the Pac-12 title game.
But it doesn't really matter: Ranked No. 1 or No. 2, that means the Ducks would play for the national title for the second time in three years.
As for the rest of the Pac-12 in the AP poll, Stanford was 14th, Oregon State 15th, UCLA 17th and USC 21st.
