College football rankings: Georgia tops list of 13 remaining undefeated teams after six weeks of 2021 season

There are 13 undefeated college football teams left with eight weeks left to play in the 2021 season, including the all-important conference championship games. While history tells us that number will drop rapidly in the coming weeks, this point provides an opportunity to see how the teams without a blemish on their record stack up against each other. 

Since the season has been defined by dozens of upsets of ranked teams and the kind of chaos that has fans invoking the spirit of 2007, it should come as no surprise that this number is down from where it was at the exact same point in 2019 (16 undefeated). All of the programs listed below enter the weekend believing that continuing their winning ways will provide the opportunity to compete for a College Football Playoff spot in November and early December. However, we know that not everyone carries the same margin for error, and even the first loss can lead to a swift drop from the category of playoff contenders. 

We are guaranteed to see at least one of these undefeated teams lose in Week 7 as Georgia and Kentucky square off in the SEC on CBS Game of the Week. The Bulldogs are heavily favored in the game, as they will be the rest of the way, which is why Kirby Smart’s squad leads off our power ranking-style breakdown of the remaining unbeaten.
