With the exception of a lone few, many of the best teams in college football have tripped up in November, and Week 13 was no exception. The results greatly shook up the Week 14 BCS standings.
But just as common as the improbable upsets were the stellar performances on the big stage, with a number of teams putting themselves into position for BCS, and perhaps national title, glory.
Here is a look at the schools that saw the biggest shifts in positioning from Week 13 to Week 14 in the BCS standings.

Oregon Drops from No. 5 to No. 13
The title of top dog in the Pac-12 has shifted back and forth between Oregon and Stanford every weekend since the two teams played. The Ducks held the top perch until they were throttled by the Cardinal, only to see Stanford lose to USC the following week and put Oregon back into the title picture.
Then, of course, Oregon went on the road against Arizona and was beaten soundly by the Wildcats, 42-16. Marcus Mariota's already small chances at a Heisman Trophy are gone, and the Ducks defense that was once a force is now diminishing by the week.
The Ducks, despite getting beaten up by Stanford a few weeks back, entered Week 13 with fringe national title hopes, still ranked in the Top Five. All of that is now over with, and it will be an uphill battle for the Ducks to get into the BCS hunt and even into the Top 10 after this woeful result.
Oklahoma State Rises from No. 10 to No. 7
The race for the Big 12 seemingly came down to Saturday night's highly anticipated showdown between Baylor and Oklahoma State, and it wasn't even close. The Cowboys pulled out a 49-17 victory in a game that was over by the end of the third quarter.
Defense hasn't been a strong point in the Big 12 as of late, but the Cowboys held the potent Baylor offense to just 17 points, and Oklahoma State quarterback Clint Chelf out-dueled Baylor's Bryce Petty in a game that was sure to be a shootout.
Whether it's the impressive defense or an offense that can go the distance on any given play, Oklahoma State is undoubtedly the most dangerous squad in the Big 12. The Pokes are a win against Oklahoma away from securing the Big 12 Championship and an automatic BCS bid.
Texas A&M Drops from No. 12 to No. 21
Although Oregon's loss shook up the top half of the standings, no school fell more over the weekend than the Aggies.
Texas A&M went into Baton Rouge with a chance to knock the LSU Tigers out of the Top 25 and keep its BCS hopes alive but was knocked around on both sides of the ball. Les Miles' squad walked out with a 34-10 victory.
With Johnny Manziel's NFL draft decision looming and a defense that has more holes than not at the moment, this team has quickly shifted from a national title contender to a squad fighting for a spot in the Top 25.
The Aggies nearly came out with wins in each of their two previous losses to Alabama and Auburn, and Manziel played some of his best games in those losses. But that couldn't be further from the truth against LSU, as Texas A&M was kicked around for the entire 60-minute contest.
