The 2005St. Louis Rams season was the team's 68th year with the National Football League and the 11th season in St. Louis. The season proved to be a "dark" year for the Rams as they won only six regular season contests.
The news broke on October 10 when head coach Mike Martz announced he would be leaving the team indefinitely as he was diagnosed with a bacterial infection. A day before, he coached his last game in a home loss against Seattle. The Rams later announced that Martz would not return again for the rest of the season as he would be dismissed at season's end. Nevertheless, the Rams enjoyed having Martz as their head coach. Joe Vitt took over the sidelines for the rest of the season.
As running back Steven Jackson earned the starting position, this year was likely the last for future Hall of Famer Marshall Faulk, who scored just one touchdown, as reconstructive knee surgery forced him to miss next season.
