The road to a BCS title leaves very little margin for error; a few teams found that out the hard way this Saturday.
In the landscape of college football, teams can only afford so many mistakes. If you want to make a serious run at the national championship your best bet is to run the table. After this week's action, the BCS rankings should see quite the shakeup as some teams had their weaknesses exposed.
Here's a look at three of the day's biggest upsets that will have a huge impact on the BCS picture.
Kent State 35 Rutgers 23
Considering the schedule that Rutgers has faced this season, it's not at all surprising that Rutgers lost a game. However, not many people saw them losing to a MAC team at home.
The Golden Flashes ruled the day with a physical ground attack that racked up 224 rushing yards. The fact that the defense forced the usually effective Gary Nova to throwing a mind-boggling six interceptions was a deciding factor as well.
With Rutgers experiencing its first loss of the season in such surprising fashion, it wouldn't be surprising to see the formerly No. 15 Scarlet Knights completely disappear from the poll next week.
Arizona 39 USC 36
Thanks to a big name and an opportunity to potentially beat Oregon twice, the Trojans weren't entirely out of the BCS title picture with their 21-14 loss to Stanford.
After losing a shootout to the Arizona Wildcats, you can stick a fork in 'em. They're done.
The Wildcats pulled off a huge upset at home as quarterback Matt Scott executed Rich Rodriguez's offensive scheme brilliantly. The senior had 369 passing yards and 100 more on the ground and outdueled Matt Barkley for the victory.
USC started the season as a trendy pick for a national championship, but after these two losses their BCS chances are all but gone.
Georgia 17 Florida 9
The takeaway here is that the SEC East race is going to get real interesting down the stretch.
The Bulldogs showed that their defense can be just as dominant as anyone's when it is it at its best. The D bottled up Mike Gillislee all game and forced six Gator turnovers to seal the win.
Anyone that questioned Florida's No. 2 rating was validated this week and we can expect to see the Gators take a considerable drop now that they've been handed their first loss.
