I wrote last week about the four NFL teams that have seen their playoff odds improve most this season, as measured by ESPN's Football Power Index (FPI). Let's go in the opposite direction and take a look at the teams whose chances of making it into the postseason have fallen off most significantly since the season began. If you like optimistic, sunny outlooks about your favorite team, this might not be the column for you.
As you can probably guess, one of the four teams whose playoff odds have declined most since Week 1 is the Kansas City Chiefs, who have fallen from virtual locks to worse than a coin flip.
