College football rankings: How preseason AP Top 25 polls shape the CFB Playoff
Top 25 rankings can make or break teams in college football. Early in the season, the AP Top 25 preseason poll gives fans an idea of which are the best teams in the country. And from there, the College Football Playoff selectors reveal their own rankings for the semifinal games that go on to determine the national champion.
But how important are the preseason rankings, really? Well, during the College Football Playoff era, they're actually a good predictor for whether or not a team will make the semifinal at season's end.

Preseason No. 1 rankings and the College Football Playoff
Of all the preseason AP No. 1 ranked teams during the College Football Playoff era, all but two have made the final four.
2014: Florida State (made CFP)
2015: Ohio State (didn't make CFP)
2016: Alabama (made CFP)
2017: Alabama (made CFP, won title)
2018: Alabama (made CFP)
2019: Clemson (made CFP)
2020: Clemson (made CFP)
2021: Alabama (made CFP)
2022: Alabama (didn't make CFP)
Ohio State in 2015 was the first preseason No. 1 team to not make the College Football Playoff, but it was close: the Buckeyes were in the top four rankings all season until Nov. 22, a day after losing to No. 9 Michigan State at home.
Alabama, the preseason No. 1 team in the AP rankings prior to the 2022 kickoff, didn't make the final four after losing two games during the regular season.
But notably, only one preseason No. 1 team has won the national championship in the CFP era: Alabama (11-1) made the Playoff despite not playing for the SEC Championship (it lost to No. 6 Auburn, the SEC West champion), jumping ahead of Big Ten champion, two-loss Ohio State.
Bama went on to win the national championship in overtime that year over Georgia (preseason No. 15), which also lost to Auburn in the regular season before winning the rematch against it in the SEC Championship Game.
Where else should you be ranked?
Few teams get the honor of being ranked No. 1 in the country in the AP preseason poll, and it's clearly not a good predictor of who will win the national championship.
So where else is a good place to be ranked? Let's take a look at where the College Football Playoff champions placed in their respective preseason polls.
2014: Ohio State (preseason No. 5)
2015: Alabama (preseason No. 3)
2016: Clemson (preseason No. 2)
2017: Alabama (preseason No. 1)
2018: Clemson (preseason No. 2)
2019: LSU (preseason No. 6)
2020: Alabama (preseason No. 3)
2021: Georgia (preseason No. 5)
2022: Georgia (preseason No. 3)
If history is any guide, future national champions need to be ranked in the top five in the preseason poll. Or if you want to get really specific, taking all the preseason polls into consideration and averaging out the eventual national champions, the best place to debut in the preseason rankings is exactly 3.333.
But it's not just top teams
Sure, everyone wants their team to rank at or near the top of the AP Top 25 poll. But it turns out, being just average could also be a good place to start out if you want to make the playoff.
One team from outside the preseason top 10 generally has a chance to make the final four College Football Playoff rankings, based on recent seasons. Provided, of course, they play a good schedule and win all their games. Which schools made the CFP ranked No. 10 or lower in the preseason?
2015: Clemson (preseason No. 12)
2015: Oklahoma (preseason No. 19)
2016: Washington (preseason No. 14)
2017: Georgia (preseason No. 15)
2018: Notre Dame (preseason No. 12)
2020: Notre Dame (preseason No. 10)
2021: Michigan (preseason unranked)
2021: Cincinnati (preseason No. 10)
2022: TCU (preseason unranked)
Of those, Clemson (2015), Georgia (2017), and TCU (2022) advanced to their respective national championship games. However, they are a combined 0-3 in those final matchups.
