There was only one FBS team that went undefeated during the 2017 college football season and that was UCF, which went 13-0 with an AAC title and Peach Bowl win against Auburn. Can any team(s) repeat the Knights' perfect season in 2018?
Here are the six remaining undefeated college football teams for the 2018 season, listed in order of their AP Top 25 ranking, then alphabetically.
No. 1 Alabama (8-0)
Next game: Nov. 3 at LSU
The Crimson Tide got off to a quick start in their game against Tennessee with 28 points in the first quarter alone. They went on to score 30 more points, ending in a 58-21 win. With the win, Alabama moved to 5-0 in the SEC. Nick Saban moved to 15-0 in games against his previous assistant coaches.
The toughest game left: Week 10 at LSU – This SEC West matchup has even more hype after LSU rocked previously undefeated No. 2 Georgia, 36-16, in Death Valley. That made the Tigers 6-1, with LSU rushing for 275 yards against the Bulldogs.
LSU is the only remaining road games for Alabama, and the Tigers are the Tide's highest-ranked opponent left on its schedule and a division rival (even if Alabama leads the all-time series 52-25-5 and has won the last seven matchups).

No. 2 Ohio State (7-0)
Next game: Oct. 20 at Purdue
It wasn't easy for most of the game, but the Buckeyes pulled away from Minnesota for a 30-14 win. Ohio State led by only 3 points at the half, but Minnesota missed two field goals before a late Dwayne Haskins touchdown pass added insurance points.
The toughest game left: Week 13 vs. Michigan – The Buckeyes still have three conference road games left against Purdue, Michigan State and Maryland, so we're highlighting their regular season finale against The School Up North.
Sure, Ohio State has won six straight against Michigan and the Wolverines haven't won in Columbus since 2000, but they've looked impressive since losing to Notre Dame to begin the season.
No. 3 Clemson (7-0)
Next game: Oct. 27 at Florida State
Clemson was ready to put up some numbers after resting during their bye week. They held NC State scoreless for the first three quarters before allowing just a single touchdown in the fourth in a 41-7 beatdown. NC State, which was also undefeated going into the game, was the Tigers' toughest remaining opponent. With no more ranked teams left on its schedule, Clemson should feel very good about its road to the ACC championship and chances of making the CFP.
The toughest game left: Week 13 vs. South Carolina – Clemson faces no more ranked opponents the rest of the regular season. South Carolina, Clemson's final game of the regular season, will be their toughest game left. The Tigers have won four straight head-to-head matchups in the annual rivalry.
No. 4 Notre Dame (7-0)
Next game: Oct. 27 vs. Navy
One week after routing ranked Virginia Tech on the road, the Irish escaped at home against Pitt, 19-14. Notre Dame trailed by eight early in the second half after a Maurice Ffrench kick return touchdown. But Ian Book passed for two touchdowns in the final two quarters to keep Notre Dame unbeaten.
The toughest game left: Week 13 at USC – Depending on how the second half of the regular season plays out, you could make the case that Notre Dame has already played (and beaten) three of the four toughest opponents on its schedule this season. The Fighting Irish already beat Michigan, Stanford and Virginia Tech, with a regular-season finale at USC still looming.
The Trojans, who were ranked in the preseason, have a top 30 defense, the benefit of home-field advantage and the potential motivation to play the role of spoiler if Notre Dame enters the game undefeated. Without a conference championship game, the Irish's College Football Playoff fate could be decided in Los Angeles.
No. 10 UCF (6-0)
Next game: Oct. 20 at East Carolina
The Knights rallied to win at Memphis, as they trailed by 16 points before scoring the final 17 points to win, 31-30. McKenzie Milton passed for 296 yards and a touchdown and added another rushing touchdown.
The toughest game left: Week 13 at South Florida – You could make a case that two games could be the toughest. Cincinnati and South Florida are both undefeated and ranked.
South Florida has already beaten Georgia Tech and Illinois, former Alabama QB Blake Barnett has filled in nicely for Quinton Flowers under center and a trip to Tampa could be the last game standing in the way of back-to-back undefeated regular seasons for UCF.
No. 21 South Florida (6-0)
Next game: Oct. 20 vs. Connecticut
The Bulls trailed Tulsa by 14 points before scoring 15 points in the fourth quarter to win, 25-24. Coby Weiss made a 22-yard field goal in the final moments to complete the rally.
The toughest game left: Week 13 vs. UCF – UCF has won 19 straight games and shows no signs of slowing down. That win streak has to mean something. With all due respect to a road game at Cincinnati in early November, a home showdown against the Knights could be the battle of undefeated teams. UCF won 49-42 last year.
