The Oregon Ducks came into Saturday with the No. 5 spot in the BCS rankings, but that will change this week after a bad loss against the Arizona Wildcats.
The Wildcats had two straight losses heading into this game and hadn't beat a ranked team all year, but that didn't keep them from winning 42-16 over the Ducks. Ka'Deem Carey was a monster on the ground, carrying the ball 48 times for 206 yards and four touchdowns for Arizona.
Marcus Mariota hadn't thrown an interception all season, but he threw two on Saturday, including this incredible first one by Arizona in the first quarter. To make things worse, he left the game in the fourth quarter after taking a big hit to the head.
The loss for the Ducks moves them to 9-2 and 6-2 in the Pac-12. More importantly, it takes Oregon out of the top spot in the Pac-12 North and will likely keep them from going to the conference championship game.
The rankings are clearly going to shake up quite a bit, and it's not going to be a pretty slide down standings for the Ducks. Not only did they lose their second of their last three games, they also got demolished by an unranked opponent. With that in mind, it's certainly realistic to think that the Ducks fall out of the Top 10.
Since the Auburn Tigers didn't play this week, they should be able to move into the No. 5 spot, but even if they do, it will be tough for them to hold onto the spot with an upcoming game against Alabama. The Tigers could also be jumped by Clemson, a team that just won 52-6 this week.
Stanford just had a big 42-13 win over California, and considering they also beat the Ducks, it makes sense to put Oregon behind the Cardinal. Missouri has a big game on Saturday night against the Ole Miss Rebels, and a win there would be big enough to have them move ahead of Oregon as well.
South Carolina will likely move into the Top 10. Oregon's loss certainly helps, and the potential for another Top 10 team losing in the game between Baylor and Oklahoma State will help as well. A 70-10 win over Coastal Carolina certainly didn't hurt, either.
The most logical spot to put Oregon at after their loss would be No. 11 just behind the Gamecocks. The only team in the Top 10 with two losses is Stanford, and with the struggles of the Ducks, they will move out of the that top group of teams in the country.
