Absence of powerhouses in AP Poll

It's been a while -- 50 years, to be exact -- since there was an AP poll without Notre Dame, Penn State, Texas and USC. It was the week of Nov. 14, 1960.

Times have certainly changed.

The No. 1 team in that poll was Missouri. Also ranked were Duke, New Mexico State, Rice, Syracuse and Yale. Two weeks later, Minnesota was crowned national champion.

• Saturday's Tennessee-Georgia game marks the first time since 1906 that both teams have losing records entering the game. The date was Nov. 21, 1906, when 1-3 Georgia hosted 1-5-1 Tennessee. Appropriately, they played to a 0-0 tie.

Since then, they've met 36 times and at least one team had a winning record. (Tennessee and Georgia haven't played every season since 1906, but they have met in each of the last 18 seasons dating back to 1992).

As for a pair of games that deal with ranked teams …

No. 7 Nebraska at Kansas State (Thursday, 7:30 ET on ESPN)

It's one of two undefeated matchups this week in FBS along with No. 17 Michigan State at No. 18 Michigan. There are 18 remaining undefeated FBS teams, and the Big 12 has five: Nebraska, Kansas State and Missouri in the North Division, Oklahoma and Oklahoma State in the South Division.

The Cornhuskers are looking for their first 5-0 start since 2003, while the Wildcats haven't started 5-0 since 2000. Nebraska has won the last five meetings -- including four in a row by at least 14 points. Kansas State hasn't beaten an AP top-10 team since 2007 when it won at No. 7 Texas, 41-21.

• The Florida Gators and LSU Tigers meet in the regular season for the 40th consecutive season. The matchup might have lost some luster with Florida's loss to Alabama and LSU's fortunate win against Tennessee, but it's still a matchup of top-15 teams, which should come as no surprise. The No. 14 Gators and No. 12 Tigers meet for the sixth consecutive season with both teams ranked in the AP top 15.

The six consecutive years meeting as top-15 teams is the longest active streak in the nation. The higher ranked team has won four of the five meetings. The next closest is Florida-Alabama, which is now at three consecutive seasons (counting 2008 and 2009 SEC Title games).
