We have a new No. 1 in our Power Rankings, and there's a chance that either of the top two teams on this list could back its way into the BCS title game:

1. Auburn (11-1, 7-1 SEC; last week: 3): Call it luck, but don't forget to call the Tigers good. Auburn won the Iron Bowl 34-28 over No. 1 Alabama on a last-second field goal return for a touchdown by Chris Davis. It was another improbable win for the Cardiac Cats, but Auburn also ran for 296 yards on the SEC's best rush defense. Back-to-back thrillers have Auburn No. 3 in the BCS standings and SEC Western Division champions.

2. Missouri (11-1, 7-1 SEC; LW: 2): These Tigers will meet those Tigers in the SEC championship game on Saturday. After beating Texas A&M 28-21 at home, Mizzou completed its own improbable season in its second year in the league. Missouri now has five wins over opponents that were ranked when it played them. Like Auburn, Mizzou is very much in the national championship picture. The Tigers need help, but a win over Auburn would push a team that was left for dead last season a step closer to Pasadena, Calif.

3. Alabama (11-1, 7-1 SEC; LW: 1): The three-peat is likely over after Alabama was bested by its archrival. Why Nick Saban would attempt a 57-yard field goal with a second left without any speedy athletes on the field is mind-blowing. Saban rarely makes mistakes, but this one will sting for a very long time. Alabama is still very much in the hunt for a BCS bowl game, but a return to the title game is a long shot.

4. South Carolina (10-2, 6-2 SEC; LW: 4): Another year, another win over Clemson. That makes five in a row for Steve Spurrier and his Gamecocks after his guys walked over the Tigers 31-17. South Carolina forced six turnovers, and quarterback Connor Shaw impressed yet again with 246 yards of offense and two touchdowns. The BCS is out of reach for the Gamecocks, but they have a shot at three straight 11-win seasons.

5. LSU (9-3, 5-3 SEC; LW: 5): This is easily the most confusing team to follow in 2013. The Tigers started hot, hit some bumps and then finished strong with an exciting 31-27 win over Arkansas. LSU was without starting quarterback Zach Mettenberger (knee) late, but it didn't matter, as freshman Anthony Jennings drove the Tigers 99 yards, with a 49-yard go-ahead touchdown pass with 1:15 left. This could be another double-digit-win season for the Tigers.

6. Texas A&M (8-4, 4-4 SEC; LW: 6): Johnny Manziel went from carving up defenses to being smothered in his last two outings. In Saturday's loss to Mizzou, Manziel was held to a season-low 216 total yards and a touchdown. The defense was gutted -- again -- allowing 225 rushing yards, including a 57-yard Henry Josey touchdown run with 3:34 remaining. It's been a long November in College Station, but at least Kevin Sumlin is locked up for the long haul.

7. Vanderbilt (8-4, 4-4 SEC; LW: 8): Coach James Franklin might be near the top of USC's coaching list, but for now, he's doing a heck of a job as Vandy's coach. There's no wonder he's on the Trojans' radar. Vandy has won four straight, will make its third straight bowl game and is in line to win nine in back-to-back seasons. The Commodores didn't make it look easy against Wake Forest, but a Carey Spear field goal with 39 seconds left kept the Dores' winning streak alive.

8. Georgia (8-4, 5-3 SEC; LW: 9): Another team that didn't want things to be easy over the weekend, Georgia needed double overtime to beat rival Georgia Tech. The Bulldogs' defense was pushed around for 495 yards, but the offense was there to bring the Dawgs back from deficits of 20-0 and 27-17. When you have a guy like Todd Gurley (158 total yards and four touchdowns), it doesn't matter who you have at quarterback.

9. Mississippi State (6-6, 3-5 SEC; LW: 10): After being on the outside of the bowl picture just a couple of weeks ago, the Bulldogs rallied to win their last two, including an overtime victory against bitter rival Ole Miss on Thanksgiving. It wasn't the prettiest of games, but injured quarterback Dak Prescott came into the fourth quarter and threw for 115 yards, while running for 29, including the eventual winning 3-yard score. Dan Mullen has Mississippi State in the postseason for the fourth straight season.

10. Ole Miss (7-5, 3-5 SEC; LW: 7): Oh, what could have been for this team. Not only have the Rebels lost two straight, but they allowed their archrivals to make it to the postseason. For a season that started 3-0, some poor play in the red zone -- especially near the goal line -- against Missouri and turnovers against Mississippi State cost Ole Miss in its final two games.

11. Tennessee (5-7, 2-6 SEC; LW: 11): A long first year for Butch Jones ended with a nice 27-14 win over Kentucky. The Vols aren't going bowling, but now is the time when Jones has to ramp up the development phase and keep an already stellar recruiting class together. Remember, this team was a fake Vandy jump pass from a bowl berth.

12. Florida (4-8, 3-5 SEC; LW: 12): The Gators' nightmare of a season ended with a 37-7 rout by rival Florida State inside the Swamp. Florida then fired embattled offensive coordinator Brent Pease and offensive line coach Tim Davis. Florida lost seven straight to end the season without scoring more than 20 points. And it isn't going bowling for the first time in 22 years and has its first losing season since 1979.

13. Arkansas (3-9, 0-8 SEC; LW: 13): With that heartbreaking loss to LSU, the Razorbacks have dropped a school-record nine straight and went 0-8 in conference play for the first time. This team fought hard in its final act, but it's clear that development and recruiting need to amp up during the offseason if Bret Bielema is going to have a chance at really competing in this league.

14. Kentucky (2-10, 0-8 SEC; LW: 14): The Wildcats have now gone 0-8 in SEC play in back-to-back seasons for the first time since 1941-42 and have lost 16 straight SEC games. Mark Stoops is building a pretty impressive recruiting class right now, but we all know it takes more than recruiting. The Wildcats need more than talent, as they took steps back on both sides of the ball late in the season.
