Two of the worst offenses in the NFL are experiencing contrasting finishes to the season.

The St. Louis Rams have finally found a rhythm and will seek their fourth straight victory when they visit the inept San Francisco 49ers on Sunday.

St. Louis (7-8) averaged 10.8 points during a five-game losing streak that stretched into Week 13, plummeting to second-to-last in the NFL in scoring ahead of only San Francisco. However, the Rams have shown offensive potential during a three-game winning streak, including last week's 23-17 upset of division rival Seattle that snapped a four-game skid on the road.

St. Louis has scored more than 20 points in three consecutive games for the first time this season, drawing a chance to finish with a .500 record for the first time since 2006. The Rams can also win four straight for the first time since posting seven consecutive victories in 2003.

The 49ers (4-11) remain the lowest-scoring offense in the NFL at 14.6 points per game, two spots below St. Louis (17.6). San Francisco is also tied for the fewest touchdowns (23) and ranks second-to-last with 240 first downs, only ahead of St. Louis' 220. The only two teams to average fewer than 300 yards are the 49ers (293.5) and Rams (293.3).

San Francisco has lost three games in a row and five of six.
