Power Rankings where nothing matters except what happens in between the white lines. No preseason rankings, recruiting talent composites or programmatic expectations are accounted for, the only formula is wins and losses as we dissect college football's top conference.

Following the Week 4 college football slate, ESPN has updated its Football Power Index (FPI) computer-generated rankings. The top three teams in the country, No. 1 Texas, No. 2 Alabama and No. 3 Ohio State, kept their positions, while Georgia moved into the No. 4 slot, and Tennessee got bumped to No. 5.

Miami, Clemson and Louisville all picked up big wins as they continue to separate themselves as the top contenders in the ACC. Meanwhile, teams like North Carolina and NC State both fell down the rankings this week as they suffered embarrassing losses.
