Alabama split the games and swept the titles.
The Crimson Tide was voted No. 1 in the final AP poll for the eighth time, tying Notre Dame for the most of any team in college football, after winning a rematch with LSU in the BCS championship on Monday night.
Alabama's 21-0 victory easily offset the Tigers' 9-6 win on Nov. 5 in Tuscaloosa, Ala., and gave it the top spot in the AP ranking to go along with the No. 1 ranking in the USA Today coaches' poll.
The Tide received 54 first-place votes and No. 2 LSU got one.
Big 12 champion Oklahoma State (12-1) was No. 3 and received four first-place votes.
Oregon finished fourth and Arkansas was fifth, giving the SEC three of the top five teams in the country.
