Still trying to get their first win of the year, the Rams came home for their Week 8 interconference duel with the Cleveland Browns.  In the first quarter, RB Steven Jackson (in his first game back from a groin injury) helped St. Louis off to an early start with a 2-yard TD run.  Afterwards, the Rams added onto their score with QB Marc Bulger completing a 1-yard TD pass to WR Torry Holt.  The Browns would get on the board with kicker Phil Dawson getting a 35-yard field goal.  In the second quarter, St. Louis' struggles continued as Cleveland took the lead with QB Derek Anderson completing a 12-yard TD pass to WR Braylon Edwards and a 21-yard TD pass to TE Kellen Winslow.  The Rams' remaining response of the half was kicker Jeff Wilkins getting a 40-yard field goal. In the third quarter, St. Louis continued to strain itself as Anderson and Edwards hooked up again to give the Browns a 5-yard TD pass.  The Rams tried to come back as Wilkins kicked a 46-yard field goal.  Unfortunately, St. Louis once again fell as Dawson nailed a 45-yard field goal for Cleveland. With the loss, not only did the Rams enter their bye week at 0-8, but they became the first team since the 2001 Detroit Lions to begin a season 0-8 after finishing the previous season at .500 or better.
