I apologize for the poor quality above but that's supposed to be a compilation of the Kansas City Chiefs rankings on ESPN's Power Rankings over the last seven years (2002-2008).
You can find this database here.
That line way at the top is from the Chiefs 13-3 season in 2003. The line way at the bottom is from the Chiefs 2-14 season in 2008.
I'd say they pegged the Chiefs about right. One great season (2003) and one (or a couple) terrible season and a bunch of mediocre seasons.
Other interesting notes:
- Patriots lowest ranking was 17th in week seven of the 2008 season.
- The Raiders chart is funny looking
- The Colts have a few straight lines at the top
- The Chiefs were 11th in week nine of the 2007 season
