Los Angeles Rams
After the 1994 NFL season, the Rams left California and moved to St. Louis, Missouri. Five seasons after relocating, the team won Super Bowl XXXIV in a 23–16 victory over the Tennessee Titans. They appeared again in Super Bowl XXXVI, where they lost 20–17 to the New England Patriots. The Rams played in St. Louis until the end of the 2015 NFL season, when they filed notice with the NFL of their intent to relocate back to Los Angeles. The move was agreed at an owners' meeting in January 2016, and the Rams returned to the city for the 2016 NFL season.
2007 Dallas Cowboys season
This would mark the first time since their Super Bowl year of 1995 that the Cowboys began a season at 8–1, and only the third time in franchise history that Dallas began at 8–1; the other times were during the 1977 season, and the 1983 season. The Cowboys won the Super Bowl in 1977 and 1995, but lost the wildcard game to the Los Angeles Rams in 1983.
