Several teams entered play either undefeated or in the national championship picture on Saturday. By the end of the day, several undefeated sides had their first loss and a few more dropped right out of national championship contention altogether.
While No. 1 Alabama, No. 3 Kansas State and No. 4 Notre Dame all passed big tests—and No. 2 Oregon continued to put up as many points as you would expect from the basketball team—several schools weren't able to keep pace.
No. 8 Florida no longer controls its own destiny in the SEC after losing to No. 6 Georgia.
Like every team before them, No. 18 Mississippi State was brushed aside by Alabama.
No. 13 Oregon State's dream season was rustled awake with a glass of cold water in a loss to Washington.
No. 25 Rutgers fell behind No. 10 Louisville in the Big East race after losing its first game of the season to Kent State.
Meanwhile, the dream died for a few teams that came into the game with a loss but still had BCS aspirations. No. 17 USC was shockingly upset by Arizona, ending their national championship hopes, while No. 12 Oklahoma was outclassed in its own building by a Notre Dame team that must now be taken seriously.
The Big Ten had an illuminating weekend as well. While Ohio State remained undefeated by beating Penn State, the Buckeyes aren't eligible for postseason play. Two teams that are and were ranked coming into the week, Michigan and Wisconsin, dropped games to No. 21 Nebraska and Michigan State, respectively.
That leaves Nebraska as the favorite to win the Big Ten title.
Next week will feature more crucial games atop the rankings. Alabama and No. 5 LSU will do battle for SEC West supremacy, while Oregon will face a USC team that could give it trouble (if it has recovered from a disappointing loss, that is).
Kansas State could be in trouble if it underestimates No. 24 Oklahoma State, while Notre Dame must avoid a letdown against Pittsburgh.
