Week 15 of the college football season marks the final opportunity for teams to change their BCS fate, as a full slate of conference championship games are on the schedule.
These final games will likely stir up the BCS standings, and we're still feeling the reverberating pulse of Auburn's huge last-second victory over Alabama in Week 14.
Speaking of Alabama, the Crimson Tide had been atop the BCS rankings since the first release, and most people expected Nick Saban's bunch to win a third straight national title.
So which team is the new No. 1?
Here's an updated look at the latest BCS rankings, followed by a closer examination of what transpired in Week 14 to shape them.
Obviously, Alabama's loss to Auburn was the biggest story of last weekend's happenings. Truth be told, given the fact that we're in the final year of the BCS, it's fitting that one of the best teams in the nation won't have a chance to compete for a title after that loss.
The entire system has been embroiled in controversy since its inception back in 1998, and most fans can't wait for the playoff system next year.
Back to the game, 'Bama had a chance to play for overtime, but Nick Saban's decision to attempt a 57-yard field goal to win it as the clock expired backfired on him in embarrassing fashion.
As noted by Bleacher Report, Chris Davis returned the kick from nine yards deep in his own end zone and returned it the distance to give Auburn one of the most thrilling victories in school history.
The loss dropped Alabama down to the No. 4 spot, bumping Florida State, Ohio State and Auburn up one spot apiece.
The Seminoles easily downed the toothless Florida Gators in Week 14 to improve to 12-0 on the season, but Ohio State barely got past Michigan at The Big House on Saturday.
It took an interception on a last-second two-point conversion attempt to pull out the win, and the Buckeyes escaped with a one-point win.
Clemson dropped seven spots after losing badly to South Carolina, 35-17. It was only the second loss of the season for the Tigers, but after getting slammed by both FSU and South Carolina this year, the No. 13 rank seems about right.
According to ESPN Stats & Info, it was the fifth straight win for the Gamecocks over Clemson:
South Carolina has won 5 straight meetings vs Clemson, the longest South Carolina win streak in series history— ESPN Stats & Info (@ESPNStatsInfo) December 1, 2013
All the teams below Clemson until the No. 13 rank received a one-spot bump—including Oregon, which barely got past Oregon State, 36-35, to maintain a 10-2 record.
UCLA received a nice boost after taking down USC, moving up four spots, and Duke did the same after taking down North Carolina, but the Blue Devils have a huge test upcoming in the ACC Championship Game against FSU that will likely knock them out of the rankings altogether.
Wisconsin dropped precipitously, losing by a touchdown to Penn State, and Fresno State also received a huge bump down the list after getting beaten by San Jose State.
There's just one more weekend of action to go before the final BCS standings are revealed, and fans can expect an incredible finish to the season. The conference championship games will likely shake up the rankings, and you can be sure there will be plenty of controversy to discuss afterward.
