The 1996 St. Louis Rams season was the team's 59th year with the National Football League (NFL) and the second season in St. Louis.
 It was marked by a 59–16 victory over the Atlanta Falcons in week 11.

 The Rams finished the regular-season with a record of 13–3, and the NFC West Championship.
The 2011 San Francisco 49ers season was the franchise's 66th season overall, and 62nd in the National Football League (NFL).
 It is the first season under head coach Jim Harbaugh and general manager Trent Baalke.
 The 49ers rebounded from their disappointing 2010 season to end their streak of eight consecutive non-winning seasons.
 After defeating the St. Louis Rams in week 13 and attaining a 10–2 record, the team clinched the NFC West and made their first playoff appearance since 2002 (under head coach Steve Mariucci).
 The 49ers ended the regular season with a 13–3 record, their best since 1997 and earned a bye in the first round of the playoffs.
 In the Divisional Playoffs they defeated the New Orleans Saints 36–32 and were in the NFC Championship for the first time since 1997 where they lost against the New York Giants 20–17 in overtime, coming just short of returning to the Super Bowl for the first time since 1994.
 Despite their most successful season in years, the 49ers were 31st in the league in third down conversion percentage in the regular season (29.1) and were 17.9 percent in the playoffs.
The 2007 St. Louis Rams season was the 70th season for the team in the National Football League and their 13th in St. Louis, Missouri.
 This was the third worst season for the Rams during their time in St. Louis.
 The team looked to improve on its 8-8 record from 2006.
 However, the Rams slumped early, losing their first 8 games of the season heading into their bye week.
 Following their bye, they would beat both New Orleans and San Francisco on the road before losing 5 of their last 6 games to conclude the season.
 The Rams 0-8 start to the season is the worst in franchise history and matched their 3rd ever longest losing streak.
 The Rams also went 1-7 at home in 2007, the worst in franchise history until it was broken by the 2009 team 2 years later.
 The Rams defense was dismal, and was the biggest scar on the team the entire season, as they allowed the 2nd most points in the league during the season with 438.
Michael Martz (born May 13, 1951) is a former National Football League (NFL) head coach and offensive coordinator.
 He is best known as the offensive coordinator behind the St. Louis Rams high-powered 1999 team which won the Super Bowl.
 As a head coach in the NFL, Martz's St. Louis Rams teams compiled a 56–36 record in his 5⅓ seasons as head coach.
 His teams reached the playoffs four times and won two division titles including a NFC championship and a trip to Super Bowl XXXVI.
The 1976 Los Angeles Rams season was the team's 39th year with the National Football League and the 31st season in Los Angeles.
 The Rams continued their dominance of the NFC West, winning their 4th straight division title as well as their 4th straight playoff berth.
 After a record setting 1975 season in which their defense was nearly untouchable, the Rams were picked by many to win the Super Bowl.
 Despite not improving on its 12-2 record from 1975, the team continued to be one of the best in the NFL.
 This Rams team is quite notable for setting many records during the season.
 One good notable record was breaking the franchise record for points scored in a game with 59 in a 59-0 devouring of the Atlanta Falcons.
 The Rams would ultimately have another year of success, finishing 10-3-1.
 In the playoffs, they would beat Dallas 14-12 in the Divisional Round of the playoffs.
 However, the Rams would lose the NFC Championship game to the Minnesota Vikings 24-13.
Orlando Lamar Pace (born November 4, 1975) is a former professional American football player who was an offensive tackle in the National Football League (NFL) for thirteen seasons.
 He played college football for Ohio State University, and was twice recognized as a unanimous All-American.
 He was drafted by the St. Louis Rams, first overall in the 1997 NFL Draft, and played professionally for the Rams for twelve years.
 Pace started all 16 regular season games eight times in his pro career, and blocked for three straight AP NFL MVPs (Kurt Warner in 1999, 2001; and Marshall Faulk in 2000).
 He was the cornerstone of a Rams offensive line that blocked for an offense that compiled more gross yards than any other team during his 12 years in St. Louis (50,770 in 12 seasons), finished second in completion percentage (61.8 percent) and fifth in touchdown passes (289) over that time.
 Under Pace's protection, the Rams' passing offense compiled more than 3,000 yards in all 12 of his NFL seasons, seven different quarterbacks eclipsed the 3,000-yard mark in a season, including three times surpassing the 4,000-yard mark, and blocked for seven 1,000-yard rushers.
 Pace started 154 consecutive games, playing with the St. Louis Rams and Chicago Bears (2009).
The 2003 St. Louis Rams season was the team's 66th year with the National Football League and the ninth season in St. Louis.
 The Rams were coming off a disappointing 7–9 season and former MVP Kurt Warner was demoted to backup quarterback; Marc Bulger earned the starting job after replacing Warner in 2002 and winning six of his seven starts.
 Though many agree that The Greatest Show on Turf ended after the 2001 season, the Rams nonetheless finished 12–4, winning the NFC West, only to lose to the eventual NFC champions Carolina Panthers.
The 1971 Los Angeles Rams season was the team's 34th year with the National Football League and the 26th season in Los Angeles.
 The team looked to improve on its 9-4-1 record from 1970.
 The Rams would finish one game below their goal, as they finished 8-5-1 and finished 2nd in the NFC West behind the San Francisco 49ers.
 The Rams would start out strong, as they started 4-1-1 in their first 6 games before splitting their final 8 games.
 Despite sweeping the 49ers on the season (the 49ers would win the NFC West at 9-5), a crucial tie against the Atlanta Falcons in week 2 proved to doom the Rams, because had they beaten Atlanta, they would've clinched the NFC West by virtue of their sweep over the 49ers.
