The term "Greatest Show on Turf" was not used to describe the Rams offense until several weeks into the 2000 season; initially the nickname for the Rams offense had been "The Warner Brothers", a play on the movie studio and a reference to new quarterback Kurt Warner, who'd assumed leadership from center after slated starter Trent Green was injured against San Diego in the preseason, and his receivers. The first appearance of the term came when ESPN's Chris Berman, preparing to cover highlights of a 57-31 win over the San Diego Chargers that year, said to television audiences, "Forget Ringling Brothers; the Rams are the Greatest Show on Earth." Over the following weeks, "Earth" was replaced with "Turf" to signify the artificial playing surface of the Trans World Dome and how it magnified and enhanced the Rams' already speedy offense. The term was retroactively applied to the 1999 team, as the offensive philosophy and key players were the same.
