ESPN’s computer model has a new No. 1 team, as the Ohio State Buckeyes dropped out of the No. 1 spot, after Ryan Day’s team gave up a ton of yards in a win over Illinois on Saturday afternoon.
How does ESPN’s FPI work, though?
Here’s how ESPN’s computer model works
“The Football Power Index (FPI) is a measure of team strength that is meant to be the best predictor of a team’s performance going forward for the rest of the season. FPI represents how many points above or below average a team is. Projected results are based on 20,000 simulations of the rest of the season using FPI, results to date, and the remaining schedule. Ratings and projections update daily. FPI data from seasons prior to 2019 may not be complete,” ESPN writes.
