The St. Louis Rams have gone from finishing 1-15 a year ago to fighting for a playoff berth in prime time on the final weekend of the 2010 regular season.
Thanks to @michaelaurban for phrasing it that way.
A few others have asked when the last time the St. Louis Rams played in prime time, as if it might have been a long time ago. It's been three seasons.
The chart lists 'em since 2004, with links to recaps on ESPN.com.
