Week 6 of the college football season is in the books. 

ESPN has updated its Football Power Index (FPI) after a wild week in college football. Six Big Ten teams are included in the top 25 this week.

Four of those six teams won this weekend. The two teams that didn’t — Nebraska and Penn State — each played a fellow member of the FPI top-25, and lost by a field goal in both instances.

Ohio State, Michigan and Iowa have now established themselves as College Football Playoff contenders, and Michigan State isn’t far behind. The Spartans also became one of the first teams to clinch bowl eligibility this year.

Here’s the full FPI top 25:

  1. Georgia
  2. Alabama
  3. Ohio State
  4. Oklahoma
  5. Michigan
  6. Florida
  7. Clemson
  8. Iowa State
  9. Texas
  10. Cincinnati
