The BCS rankings are composed of three equal components - the USA Today Coaches Poll, the Harris Poll, and an average of several computer rankings. The teams that are ranked No. 1 and No. 2 in the BCS rankings at the end of the regular season will meet for the national championship on Jan. 9 in New Orleans.
Fellow SEC West Division power Alabama, which will play LSU on Nov. 5 in Tuscaloosa, Ala., was No. 2. Oklahoma was No. 3 and Oklahoma State was No. 4 and those teams will meet Dec. 3 in Stillwater, Okla. The fifth spot went to Boise State, which is considered a long shot to climb any higher because of a relatively weak schedule, which will hurt it in the computer rankings.
The Tigers will play defending BCS champion Auburn, which is 20th in the BCS rankings, on Saturday afternoon in Tiger Stadium. LSU, which will play No. 9 Arkansas on Nov. 25 in Tiger Stadium, has played one of the toughest schedules in the country, meeting four teams that were ranked at the time of those meetings. The Tigers haven't won any game by fewer than 13 points.
The rest of the top 10 consists of No. 6 Wisconsin, No. 7 Clemson, No. 8 Stanford, Arkansas, and Oregon, which lost to LSU, 40-27, in the season opener Sept. 3 in Arlington, Texas.
The next five are Kansas State, Virginia Tech, Nebraska, South Carolina, and West Virginia, which lost to the Tigers, 47-21, on Sept. 24, a victory that elevated LSU to the top spot in the AP poll.
Michigan State is No. 16, followed by Texas A&M, Michigan, Houston, Auburn, Penn State, Georgia Tech, Illinois, Texas, and Washington.
