Here are five games St. Louis must win in 2015 in order to have a serious shot at the postseason.

Week 3: 9/27 Pittsburgh Steelers

The Rams need to do all they can to avoid yet another slow start under head coach Jeff Fisher. Fisher has only one season with the Rams that has started over .500 through the first five weeks. Weeks one and two bring the Seattle Seahawks at home and a road game visiting the Washington Redskins. The aging Steelers are a perfect game to flex some muscle with a shot at a 2-1 or even 3-0 start to the season. The loss of defensive mainstays Troy Polamalu, Brett Keisel and Jason Worilds significantly fractured a perennial top 15 defense. The Rams and Steelers have met 25 times in the regular season, with St. Louis leading the all-time series 15-8-2. However, the last time these two teams met in 2011 Pittsburgh shutout the Rams 27-0 in a dominant victory at Heinz Field. The Rams need a strong start and a win hosting the Steelers will turn some heads.
