LSU (12-0) knocked Arkansas from No. 3 in the standings all the way down to eighth after dumping the Razorbacks, 41-17, on Saturday.
That was the last regular season test for the Tigers, who play Georgia in the SEC Championship Game next week. Regardless of that outcome, LSU is likely to compete in the BCS title game as it holds a perfect 1.000 BCS average.
The Tigers' opponent, however, is still up for grabs. The Crimson Tide (11-1) currently hold a significant advantage over third-ranked Oklahoma State (10-1), which can possibly improve its position with wins over Oklahoma next week and in the Big 12 title game. Alabama, though, has a .955 average, compared to .871 for Oklahoma State.
Stanford (11-1) and Virginia Tech (11-1) round out the top-5, while Houston (12-0), the only other undefeated team in the nation, jumped into the sixth spot in the standings. The Cougars have one game remaining, the Conference-USA title game against Southern Mississippi.
Boise State, Arkansas, Oregon and Oklahoma completed the top-10.
The BCS system, in place since 1998, is computed by averaging the percentage totals of the Harris Interactive poll, USA Today poll and computer rankings. The top two teams at the end of the season will square off in the national championship game.
