We're down to 11 undefeated college football teams this season, with Illinois shocking No. 6 Wisconsin. But some of these teams could go down this week.
So let's have some fun. Here's a look at the toughest home, road (or neutral) games for the 12 undefeated teams, with our pick for the toughest opponent remaining in bold. All rankings are from the AP Poll unless otherwise noted.
Here's when the 11 undefeated college football teams could lose this season
No. 1 Alabama
Record: 6-0 (3-0 SEC)
Toughest remaining home game: vs. LSU (Saturday, Nov. 9)
Toughest remaining road game: at Auburn (Saturday, Nov. 30)
Trap game: at Mississippi State (Saturday, No. 16)
The good news if you're Alabama is you're not going to be an underdog. But that doesn't mean a 12-0 record and a spot in Atlanta for the SEC Championship Game is fated.
If both Alabama and LSU remain undefeated, the Nov. 9 game in Tuscaloosa will probably get hyped as the "Game of the Year," especially since the winner is likely headed to the SEC Championship Game.
Other than that, after the Tide won at Texas A&M this weekend, there aren't many daunting games left on the schedule besides LSU and then the Iron Bowl at Auburn on Nov. 30. It probably is a two-game season for 'Bama.
No. 2 LSU
Record: 7-0 (3-0 SEC)
Toughest remaining home game: vs. Auburn (Saturday, Oct. 26)
Toughest remaining road game: at Alabama (Saturday, Nov. 9)
Trap game: at Ole Miss (Saturday, Nov. 16)
There's no debate here: Alabama. The Tigers also play Auburn this month, but the Nov. 9 date at the Tide is the big one.
LSU has lost eight in a row to Alabama, with the 9-6 OT defensive struggle in 2011 the most recent triumph. But since beating Alabama 24-21 in 2010, LSU has averaged 9.1 points per game against the 'Tide. However, LSU might finally have the offense needed to win thanks to Heisman candidate Joe Burrow.
No. 3 Clemson
Record: 7-0 (5-0 ACC)
Toughest remaining home game: vs. Wake Forest (Saturday, Nov. 16)
Toughest remaining road game: at South Carolina (Saturday, Nov. 30)
Trap game: at N.C. State (Saturday, Nov. 9)
Clemson has dropped from its preseason No. 1 perch, but the Tigers might have the best chance of reaching the College Football Playoff. There are no teams currently ranked that are ahead on Clemson's schedule.
If Clemson misses out on the CFP semifinals for the first time since 2014, it could be the biggest shock of the season. If we have to pick one opponent to be the toughest, it's rival South Carolina — especially now that the Gamecocks shocked Georgia.

No. 4 Ohio State
Record: 7-0 (4-0 Big Ten)
Toughest remaining home game: vs. Penn State (Saturday, Nov. 23)
Toughest remaining road game: at Michigan (Saturday, Nov. 30)
There are two difficult home games left: Wisconsin and Penn State. But with Wisconsin losing to Illinois, getting Penn State on Nov. 23 one week before going to rival Michigan looks like the biggest trouble. Still, when two of our toughest remaining teams are coming to your place, it's difficult to not be confident.
With Ohio State's CFP troubles the last two seasons stemming from blowout road losses, the only one that looks even remotely possible to continue that streak is Michigan on Nov. 30. But OSU has lost only once to Michigan on the field since 2003 (forfeit in 2010 and 40-34 loss in 2011).

No. 5 Oklahoma
Record: 7-0 (4-0 Big 12)
Toughest remaining home game: vs. Iowa State (Saturday, Nov. 9)
Toughest remaining road game: at Baylor (Saturday, Nov. 16)
Trap game: at Kansas State (Saturday, Oct. 26)
OU got by Texas in what was probably the toughest hurdle on the schedule. But because everyone in the Big 12 play everyone else, the Sooners still have to play the league's other top teams.
That means the road trip to Baylor stands out from the rest, though the Sooners also visit rival Oklahoma State for Bedlam.

No. 7 Penn State
Record: 6-0 (3-0 Big Ten)
Toughest remaining home game: vs. Michigan (Saturday, Oct. 19)
Toughest remaining road game: at Ohio State (Saturday, Nov. 23)
Trap game: at Minnesota (Saturday, Nov. 9)
Ohio State handed Penn State its first loss in both 2017 and 2018. Any undefeated Nittany Lions season talk starts and ends with the Buckeyes. But that showdown is not until Nov. 23, with Rutgers the only team left on the schedule after that game.
So it might make more sense to focus on a possible trap game. Michigan comes to Beaver Stadium for a night game. Michigan State upset the Nittany Lions in each of the last two years. But PSU won't be overlooking those two — so they they might not fit the "trap game" label. Instead, that trip to Minnesota two weeks before Ohio State game stands out. And now the Gophers are ranked.
No. 14 Boise State
Record: 6-0 (3-0 Mountain West)
Toughest remaining home game: vs. Wyoming (Saturday, Nov. 9)
Toughest remaining road game: at Utah State (Saturday, Nov. 23)
Trap game: at BYU (Saturday, Oct. 19)
The Broncos are the Group of Five's top New Year's Six candidate (with the AAC contingent right there, too). But the schedule isn't easy.
After beating Hawai'i this week, Boise State has tough road game ahead at BYU and later Utah State. That Nov. 23 game at Utah State is probably the toughest, as the Aggies have QB Jordan Love and lost by only 9 on the Blue Turf a year ago.
If you're looking for a potentially dangerous home game, Wyoming makes the most sense. The Cowboys and upset an undefeated Boise State team in 2016.
No. 18 Baylor
Record: 7-0 (4-0 Big 12)
Toughest remaining home game: Oklahoma (Saturday, Nov. 16)
Toughest remaining road game: at TCU (Saturday, Nov. 9)
Trap game: at TCU (Saturday, Nov. 9)
Matt Rhule had to rebuild this program, and after going 1-11 in 2017 he took the Bears to a bowl win and a 7-6 record in 2018. This year, Baylor is back in the Top 25.
But it might be difficult to stay on this list much longer. The Bears scored the final three touchdowns to defeat Oklahoma State, but there are three consecutive weeks of TCU, Oklahoma and Texas to start November.
No. 19 SMU
Record: 7-0 (3-0 AAC)
Toughest remaining home game: vs. Tulane (Saturday, Nov. 30)
Toughest remaining road game: at Memphis (Saturday, Nov. 2)
Trap game: at Houston (Thursday, Oct. 24)
SMU is ranked for the first time since 1986. The Mustangs are the last remaining undefeated AAC team, but the conference looks tough. Of all the hard games, the Nov. 2 matchup at Memphis is above the rest. The Tigers have defeated the Mustangs by 38, 63, 44, 21 and 10 in the last five years.
No. 20 Minnesota
Record: 7-0 (4-0 Big Ten)
Toughest remaining home game: vs. Penn State (Saturday, Nov. 9)
Toughest remaining road game: at Iowa (Saturday, Nov. 16)
Trap game: vs. Maryland (Saturday, Oct. 26)
The Gophers are 7-0 after routing Nebraska (34-7) and Rutgers (42-7) in consecutive weeks. But Minnesota still has to prove itself against a ranked team.
Still, 8-0 is looking very possible for the Gophers. The problem is that Minnesota plays Penn State, Iowa and Wisconsin in November. Take your pick out of that lot, but Penn State might be the toughest out.
No. 24 Appalachian State
Record: 6-0 (3-0 Sun Belt)
Toughest remaining home game: vs. Georgia Southern (Thursday, Oct. 31)
Toughest remaining road game: at South Carolina (Saturday, Nov. 9)
Trap game: at Georgia State (Saturday, Nov. 16)
App State impressively drove 97 yards in 10:11 on 19 plays to win at Louisiana in Week 7 in likely the toughest conference game on the schedule.
But it's the Mountaineers' road game at South Carolina that is now the most likely stumbling block — and the Gamecocks just beat then-No. 3 Georgia. Appalachian State beat North Carolina earlier this season.
The Mountaineers have a surprisingly deep history against South Carolina. They are 1-8 against the Gamecocks, winning 39-34 in 1975.
