The 2000 season was the St. Louis Rams' 63rd in the National Football League (NFL) and their sixth in St. Louis. For the first time in franchise history, the Rams entered the season as the defending Super Bowl champions. The Rams finished the regular-season with a record of 10–6 but would go on to lose to the New Orleans Saints 31–28 in the wild-card round of the playoffs. They led the NFL in scoring for a second straight year with 540 points. The Rams became the first team in NFL history to score more than 500 points on offense, while allowing more than 450 points on defense.
The 2001 season was the Kansas City Chiefs' 32nd in the National Football League (NFL) and their 42nd overall. It was their first year under head coach Dick Vermeil and 13th under general manager Carl Peterson. They finished the regular season with a 6–10 record.
The 1997 season was the Kansas City Chiefs' 28th in the National Football League (NFL) and their 38th overall. The Chiefs improved on their 9–7 record from 1996, and finished with a 13–3 record and as AFC West division champions. The Rich Gannon–Elvis Grbac quarterback controversy was a focal point of the team's season. It brewed throughout the entire season and arguably cost the Chiefs a victory in the playoffs. The Chiefs were defeated by division rival and eventual Super Bowl champion, Denver Broncos, in the 1997 playoffs. 1997 was the final season the Chiefs appeared in the playoffs during the 1990s and for the next several seasons, they fell into futility. They did not return to the playoffs until 2003.
The 2005 season was the New Orleans Saints' 39th in the National Football League (NFL) and the sixth and final under head coach Jim Haslett.
The 2011 season was the St. Louis Rams' 74th in the National Football League (NFL), their 17th in St. Louis, and their third and final season under head coach Steve Spagnuolo.

The day after the season finale, head coach Steve Spagnuolo and general manager Billy Devaney were fired from the team.
The 2012 season was the St. Louis Rams' 75th in the National Football League (NFL), their 18th in St. Louis and their first under head coach Jeff Fisher. Finishing at 7–8–1, they improved on their 2–14 record from 2011. In Week 10 against the San Francisco 49ers, the game ended in a 24–24 tie, the first since the 2008 NFL season. It was Sam Bradford's second and final full season as the Rams starting quarterback as two torn ACLs sidelined him for much of the next season and the entire 2014 season.
The 2013 Tennessee Titans season was the franchise's 44th season in the National Football League (NFL), the 54th overall, the 17th in the state of Tennessee and the third and final under head coach Mike Munchak. It was also the final season under the ownership of founder Bud Adams, who died on October 21. The Titans slightly improved on their 6–10 record from 2012 but missed the playoffs for a fifth consecutive season.
The 2013 season was the St. Louis Rams' 76th in the National Football League (NFL), their 19th in St. Louis and their second under head coach Jeff Fisher. The Rams equaled their win total from 2012, but missed the playoffs for a ninth consecutive season.
The 2014 season was the St. Louis Rams' 77th in the National Football League (NFL), their 20th in St. Louis and their third under head coach Jeff Fisher. The Rams attempted to reach a playoff berth for the first time since their 2004 season, but were officially eliminated in their loss against the Arizona Cardinals in Week 15. The Rams failed to improve on their 7–9 record from 2013, finishing 6–10 in 2014. The Rams' 2014 season was notable for their numerous starting quarterbacks including Austin Davis, Shaun Hill, and Sam Bradford, the last of whom was injured before the season began. Despite the lack of stability at the position, the Rams defeated both defending conference champions, Super Bowl participants, and 2014 division winners, the Seattle Seahawks and Denver Broncos, plus also shutting out two teams in consecutive weeks: the Oakland Raiders and Washington Redskins. This represents the most recent last-place finish in the NFC West for the St. Louis/Los Angeles Rams.
