There was a changing of the guard in some circles of college football on Saturday, and those changes have been reflected in the latest edition of the AP Top 25 rankings that were released on Sunday.

Three teams in last week's Top 10—LSU, Florida State and Georgia—got knocked from the ranks of the unbeaten.

LSU and Georgia at least have the luxury of losing to teams also ranked in the Top 10,—Florida and South Carolina—but Florida State laid an egg in the second half against N.C. State. The Seminoles were outscored 17-0 in the last 30 minutes, including 14-0 in the fourth quarter.

The Big Ten and Big 12 also provided plenty of drama that has been reflected in these rankings. Not only did you have a shootout in Texas between Heisman favorite Geno Smith against the Longhorns but Ohio State and Nebraska stole the show in prime time with 101 combined points.

As much fun as we have at the expense of the Big Ten, at least we finally got to see a shootout that made the conference watchable, even though it really is dreadful football.

Further down the chain, TCU and Northwestern each lost its first game of the season. It was a crazy, unpredictable weekend, though not an entirely unexpected one. This is the time of year when you start to see the wheat separated from the chaff.

Next week doesn't let up on marquee battles, as Notre Dame hosts Stanford, LSU and South Carolina duel in Baton Rouge and the Red River Rivalry gets renewed between Texas and Oklahoma.
