What a difference a week makes in college football, especially one marked by statement wins by and against new rivals created by conference realignment, and as expected, there was some movement in ESPN’s top 25 rankings heading into Week 5.

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.

Here is where things stand in ESPN’s new top 25 college football rankings looking ahead to the Week 5 games.

Rankings change: Down 3

Win projection: 6.5 games

Rankings change: None

Win projection: 8.2 games

USC's defense is certainly better than it used to be, but a loss at Michigan in the school's Big Ten debut proves there's still room for improvement as the unit was bossed around early on, and especially late in regulation when it couldn't hold a fragile 3-point lead.
