The top three teams from the AP poll were all off this week, the first time that's occurred in more than two decades, so the most notable changes in the new college football rankings came from the team that's hoping to re-establish itself as a College Football Playoff contender. 

Georgia jumped from No. 8 to No. 6 in the new AP Top 25 after beating Florida in Jacksonville, Florida,  on Saturday. The Bulldogs are now the top-ranked one-loss team in the country, as they look to carry momentum from the strong performance on toward not only winning the SEC East outright but claiming a second SEC Championship in three years. The Gators fell to No. 10 after the loss, ranked just behind No. 9 Oklahoma but ahead of undefeated No. 11 Baylor. 

LSU remains No. 1 and Alabama is No. 2 ahead of their showdown on Saturday, the first time No. 1 will play No. 2 in the regular season since 2011.

Other movement in the new AP poll included Memphis moving up five spots to No. 19 after beating previously undefeated SMU, who fell eight spots to No. 23 after the loss. Navy, now at 7-1 and right in the thick of that AAC West race along with both Memphis and SMU, also made its first appearance of the season in the AP Top 25, checking in at No. 25. 

Four of the top five teams in the country were off in Week 10, and the only one that wasn't, Clemson, hosted Wofford in a runaway victory. So when the new college football rankings were released on Sunday, it didn't come as a surprise to see no change among the top five in the Coaches Poll. 

But after that, there were changes in the rankings, the most notable being adjustments following Georgia's big win against Florida in Jacksonville, Florida. The Bulldogs, now 7-1, moved up to No. 6 following the victory, just one spot behind the five undefeated teams at the top. The coaches were particularly unkind to Florida after the defeat, dropping the Gators down five spots to outside the top 10 at No. 11. 

Memphis made the biggest move up in the Coaches Poll, now four spots higher at No. 19 following its win against SMU on Saturday night in the Liberty Bowl. The Mustangs, no longer undefeated, had one of the biggest drops of the week but remained in the top 25 at No. 23. Combined with Cincinnati and Navy, making its first poll appearance of the season, the AAC has more teams ranked in the Coaches Poll than the ACC, Big 12 and Pac-12.
