As a college football enthusiast, I've always been curious about how the rankings are calculated. After doing some research, I learned that the rankings are determined by a combination of human polls and computer algorithms. The two main polls are the Associated Press (AP) poll, which is voted on by sports journalists, and the Coaches Poll, voted on by a panel of college football coaches. Meanwhile, the computer algorithms take into account factors like win-loss records, strength of schedule, and opponents' performances. Ultimately, these factors come together to form the rankings we see each week during the season.
