A month from now, the 13 members of the College Football Playoff selection committee will reveal their first rankings of the season.
Here is a look at some of the teams who have a chance to earn one of the top four semifinal spots.
Alabama (5-0): The Crimson Tide are becoming a fixture in the playoffs, appearing in the semifinals during the past four seasons. Armed with an offense that ranks among the top five nationally, Nick Saban's team appears to be the only true favorite to return in 2018.
Georgia (5-0): The Bulldogs are projected to win the remainder of their regular season games, according to ESPN's Football Power Index. The perfect run would put them in the SEC Championship Game again. If Georgia is No. 2 in the playoff rankings at that point, could an SEC title game loss to Alabama drop it out of the top four spots?
Ohio State (5-0): The Buckeyes won the Big Ten Championship last season, but they were bumped out of the semifinals by Alabama. It's almost certain that Ohio State returns to the Big Ten title game and if Urban Meyer's team is undefeated, it's hard to see how they could be left out for a second consecutive season.
Clemson (5-0): A down year for the ACC isn't going to help Clemson's case in the eyes of the committee. The Tigers were resilient in surviving an upset bid by Syracuse, but the rest of the regular-season schedule is weak. If Clemson reaches the ACC title game, it will face a Coastal Division challenger with at least one loss.
LSU (5-0): The Tigers are a longshot, especially with a schedule that features three games against ranked teams in the month of October (Florida, Georgia and Alabama). If _ and it's a big if _ LSU can do what Auburn did last season and beat all three, there's no way Ed Orgeron's team isn't in the playoff semifinal conversation.
Notre Dame (5-0): Notre Dame was in the playoff mix last season, entering the rankings at No. 3 despite suffering a loss to Georgia in the second week of the season. The Irish didn't stay long after losing to Miami a week later. This year, the schedule is much easier and the offense is much better.
Oklahoma (5-0): The Sooners are looking to earn back-to-back semifinal bids, but to do so they'll need to survive a regular-season schedule that features showdowns against Texas, Texas Tech, Oklahoma State and West Virginia plus a Big 12 Championship game.
Auburn (4-1): It's possible the Tigers could find their way into the playoff mix, but the margin for error is razor thin. All Auburn needs to do is go undefeated the rest of the season, including wins over Georgia and Alabama, and hope LSU stumbles. Then go win the SEC title. Easy, right?
West Virginia (4-0): If anyone is going to challenge Oklahoma in the Big 12, it could be West Virginia. The Mountaineers would have to finish among the top two teams in the league and win the conference title game. A one-loss Big 12 champion could contend for a semifinal bid.
Washington (4-1): The Huskies are the highest-ranked team in the Pac-12 at the moment and feature one of the weakest schedules among the top 10 teams. Much like any of the other one-loss teams on this list, there's little room for error, meaning Washington needs to win out and hope for some help.
Penn State (4-1): After falling to Ohio State, it will be difficult to earn a Big Ten championship. If the Nittany Lions can earn wins over ranked teams like Michigan and Wisconsin and hope Ohio State slips up along the way, maybe Penn State can still earn a semifinal bid.
UCF (4-0): Playoff director Bill Hancock said UCF has a path the playoff, but considering the Knights were 13-0 last season and couldn't get higher than No. 12 in the rankings, it seems like a longshot — especially as conference opponents Memphis, East Carolina and Temple continue to underperform.
Kentucky (5-0): The Wildcats have a 1.7 percent chance of winning the SEC, according to ESPN's Football Power Index, and it's easy to see why with showdowns against Texas A&M, Missouri and Georgia still on the schedule. Kentucky has been proving doubters wrong all season. Can they keep doing it and earn a shocking playoff semifinal bid?
Stanford (4-1): Stanford's path to the playoff runs through the Pacific Northwest with a mid-November showdown with Washington a major hurdle left to clear. Beat the Huskies and win the Pac-12 title and there's a chance the Cardinal could be in the semifinal mix, especially with Stanford boasting a top-15 schedule.
Michigan (4-1): The Wolverines have managed to bounce back nicely after an early loss to Notre Dame, but October is scary with back-to-back-to-back games against Wisconsin, Michigan State and Penn State. If Jim Harbaugh's team survives and can finally beat Ohio State, that's huge.
Wisconsin (3-1): The loss to BYU hurts — it really hurts. The Badgers overall strength of schedule wasn't great to begin with and losing to the Cougars wasn't ideal. The Big Ten West is winnable, but games against Michigan and Penn State could put an end to any playoff talk sooner rather than later.
Miami (4-1): The ACC isn't doing Miami any favors. The Hurricanes are 0-1 against ranked teams so far this season and with just Virginia Tech as a possible future ranked foe, there isn't much juice left in the schedule. Of course, win out and beat Clemson in the ACC championship and it might not matter.
