After an action-packed weekend of college football that saw some highly-ranked teams on the losing end of things, here is your updated look at the ESPN top 25 rankings as we head into Week 8.

Football Power Index (FPI) college football rankings and computer prediction model are a measure of team strength that predicts a team’s future performance. 

Rankings and scores predictions are based on 20,000 simulations of a team’s season and games, using a combination of key analytics, including scores to date, quality of opponents, team talent, recruiting, and a team’s schedule.

Teams are ranked not in order of talent like in other rankings, but by a projected point margin per game against an average team on a neutral field.
