GRAPEVINE, Texas -- You think you have it all figured out, don't you?

Four playoff spots, four undefeated Power 5 teams.

Fine.

But, um, who's No. 2?

The first College Football Playoff rankings of 2016 will be revealed Tuesday at 7 p.m. ET on ESPN, and while the playoff picture seems relatively simple with Alabama, Clemson, Michigan and Washington all still undefeated, the selection committee probably won't use alphabetical order to figure out its top four.

There are still some questions for the 12 members of the selection committee, who began their first official rankings meeting Monday afternoon and reconvened Tuesday morning. The evening's reveal will provide the first insight into how they view the top contenders. Here's a look at the most pressing questions heading into the first rankings:

1. Who's No. 2? Alabama has looked like the most complete team in the country and the clear No. 1 for the past nine weeks, but who follows? Not all undefeated records are created equal. Clemson has three marquee wins against ranked opponents in Auburn, Louisville and Florida State, but hasn't looked dominant against the likes of Troy and NC State. Michigan has looked dominant, particularly on defense, but has left its home state only once all season -- and that was to play a 2-6 Rutgers team. Washington's first road win against a ranked opponent in Utah couldn't have come at a better time -- but that's the lone highlight on its playoff résumé. The case can be made for and against each team, so which way will the committee lean?

2. How are the one-loss teams ranked? The one-loss club has grown significantly since West Virginia, Baylor and Nebraska joined this past weekend. Ohio State, Louisville, Florida and Texas A&M are also still clinging to playoff hopes. How the committee initially ranks these teams will give an indication of whether any of them have a shot at cracking the top four without winning a conference championship. The Big 12 is still up for grabs but doesn't have a conference championship game. Ohio State and Nebraska can still win their respective divisions in the Big Ten. Florida would have a monumental task upending Alabama in the SEC title game, should that matchup occur, and the Aggies need to win out and look spectacular in the process.

3. Does any two-loss team stand a chance? Remember last year's Stanford team, which lost to Northwestern and Oregon? The Cardinal were in the mix as a two-loss Pac-12 champion and finished No. 6. -- ahead of one-loss Ohio State -- in the final CFP rankings. Is there a two-loss team out there that the committee views similarly? Auburn is surging, but it needs to win out and have Texas A&M lose again to win the West. LSU's only league loss was to Auburn, so it can still win the West if it wins out and the Tigers lose again. Wisconsin now owns the tiebreaker over Nebraska if the Huskers lose again, and they play at Ohio State this week. Oklahoma hasn't lost a Big 12 game yet, and Utah can still win the South and get a second shot at Washington in the Pac-12 title game.

4. Who leads the Group of 5? Boise State had been the front-runner until its 30-28 loss at Wyoming on Saturday. Will the selection committee reward undefeated Western Michigan, which has road wins at Northwestern and Illinois? A two-loss Boise State team was ranked ahead of an undefeated Marshall in 2014, which spoke volumes about what the committee thought of Marshall's strength of schedule that season. Because of its road wins over Big Ten teams, Western Michigan should be able to make a stronger case this year, but nothing is a guarantee. The highest-ranked Group of 5 champion is guaranteed a spot in a New Year's Six bowl, which would be the Cotton Bowl this season.
