No. 1 Alabama (9-0), No. 2 Notre Dame (10-0), No. 3 Ohio State (5-0) and No. 4 Clemson (9-1) have held on to the top four spots, and the Tigers are the only one-loss team of the bunch.

That should be the same four-team field when the third set of College Football Playoff rankings are released Tuesday, too. The season continues to be impacted by COVID-19, and there will be more scheduling shakeups the next two weeks.

Will there be room for some chaos on the field to break up that field? We look at the five scenarios that could upset the established order:

Notre Dame beats Clemson

No two-loss team has made the College Football Playoff since it started in 2014. Clemson, which has made five consecutive Playoff appearances, wouldn’t be immune to that if it loses to the Irish for a second time in the ACC championship game.

Clemson lost 47-40 to Notre Dame in double overtime on Nov. 7, but that was with backup quarterback D.J. Uiagalelei. Trevor Lawrence should be on the field for the rematch, and the Tigers will be favored.

Can Notre Dame pull off the sweep and win the ACC championship in its first go?

Clemson blows out Notre Dame

While the assumption is Clemson will beat Notre Dame in the rematch, there’s a strong belief the Irish would make their second CFP appearance anyway.

Barring, of course, a blowout.

The Tigers have won the last five ACC championship games by an average of 26.2 points per game. In a game where perception always matters, a blowout loss could open the door for one of those unbeaten or one-loss teams outside of the top four to sneak in.

That’s a scenario the SEC contenders are hoping happens, as well.

Florida shocks Alabama

No. 6 Florida (8-1) was the first SEC team to clinch a conference championship berth when it beat Tennessee 31-19. The Gators close out their regular season against LSU on Saturday. Florida has a Heisman Trophy contender at quarterback in Kyle Trask, and have split eight SEC championship game matchups with No. 1 Alabama.

Can Florida pull a shocker in that game that would possibly prompt the committee to put (gasp) two SEC teams into the Playoff for the second time in seven seasons?

That would be bad news for Notre Dame if it loses the ACC championship game. The Big Ten wouldn’t like that either.

Big Ten fails Ohio State

The Buckeyes improved to 5-0 with a 52-12 victory against Michigan State on Saturday. Ohio State remains the team to beat in the Big Ten, but the question of whether it can play six regular-season games remains.

Michigan did not play Maryland this week because of an increased number of positive COVID-19 tests within the program. The Game — in which Ohio State is favored by 30 points — might not be played.

What if the Buckeyes can’t find an opponent? If that is the case, then the Big Ten must consider waiving the eligibility requirement for the conference championship game. No. 14 Northwestern (5-1) would likely be the opponent in Indianapolis, and again, Ohio State would be a heavy favorite.

If the Wildcats could upset the Buckeyes, then those conversations would be interesting for the conference. The Big Ten needs to do its part to allow that matchup to happen.

Anything else?

No. 5 Texas A&M (7-1) remains in the picture, but won’t play in the SEC championship game. The Aggies can still back-door into the Playoff with victories against Ole Miss and Tennessee and some combination of the chaos mentioned above.

No. 7 Cincinnati (8-0) need to win out and have both Clemson and Florida lose to even get in the conversation. The Bearcats could use a Texas A&M loss on top of that, too. If those three things happen, then the Bearcats could become the first Group of 5 team to play in the CFP. Should we be talking about No. 14 Coastal Carolina (10-0) instead? The Chanticleers added a top-10 win against No. 8 BYU in thrilling fashion Saturday.

No. 17 USC (3-0) is still unbeaten in the Pac-12, but the Trojans need a lot more to happen to crack the field. No two-loss teams have made it, so we’re not ready to put a pair of Big 12 leaders in No. 9 Iowa State (8-2) or No. 11 Oklahoma (7-2) in the mix.
