Ranking college football coaches is something we've been doing at CBS Sports for years now, which makes our rankings ahead of the 2021 season particularly interesting as they may be the least volatile we've ever seen. There's still plenty of movement, don't get me wrong, but there are usually numerous coaches moving in and out of the top 25 each year.

With the 2021 season approaching, there are only two new entries into this year's top 25. Part of the reason for a lack of volatility inside the top 25 may have been a hesitancy to punish coaches with established track records too harshly for any possible setbacks during a strange 2020 season ravaged by the COVID-19 pandemic.

Still, while the names are the same, there are some dramatic swings regarding where these coaches are ranked.

As for how the rankings are decided, a panel of college football writers from CBS Sports and 247Sports submit ballots and vote. The ballots are compiled, and the rankings are final and irrefutable. OK, so they aren't irrefutable, that's impossible. Every single voter has their own criteria for ranking coaches. Some value accomplishments on the field above all else, while others may give greater weight to recruiting prowess or the possibility of future success.
