LSU edges past Alabama to become college football's new No. 1

Meanwhile: Oklahoma became the third top-six team in the past three weeks to lose to an unranked opponent, falling at Kansas State and dropping five spots to No. 10. And it didn't help them that Texas lost and fell out of the top 25, either.

• Yes, but: 14 of the past 20 College Football Playoff semifinalists had a loss, so the Sooners aren't dead. They just need some serious help (i.e. run the table and beat a ranked team in the Big 12 title game, at the very least).

The big picture: The eight-point margin between the top three teams is the closest since 1978. But it's a toss-up after that, with vastly different teams résumé-wise vying for that fourth and final spot in the playoff.

• The rankings don't show it, but Georgia had a brutal bye week. Their marquee win is against Notre Dame (destroyed by Michigan) and their biggest loss was to South Carolina (lost by 20 to lowly Tennessee).
• Minnesota is 8-0 for the first time since 1941 and will be off this week before hosting undefeated Penn State two Saturdays from now in the program's biggest game in decades.

In: No. 22 Kansas State and No. 24 Memphis returned to the rankings after brief stints earlier this season, while No. 25 San Diego State entered the top 25 for the first time since 2017.

• Out: Texas fell out of the rankings for the first time this season after losing to unranked TCU, while Iowa State (lost to Oklahoma State) and Arizona State (lost to UCLA) also dropped out.

Saturday's slate:

• (8) Georgia at (6) Florida
• (15) SMU at (24) Memphis
• (7) Oregon at USC

What's next: The first CFP rankings come out in a week. With Oklahoma's loss, consider the potential debate over the following one-loss teams come Selection Day:

• Oklahoma
• Oregon
• The loser of LSU-Alabama (Nov. 9)
• The loser of Penn State-Ohio State (Nov. 23)
