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.
History of the Dallas Cowboys
After a slow start in 1978, Dallas won its final six regular season games to finish the season at 12–4. After an unexpectedly close divisional playoff game against the Atlanta Falcons at Texas Stadium, the Cowboys traveled to Los Angeles and shut out the Rams in the NFC Championship Game 28–0 to return to the Super Bowl. In Super Bowl XIII, Dallas faced the Steelers at the Orange Bowl in Miami. The Steelers outlasted the Cowboys 35–31, despite a furious comeback that saw Dallas score two touchdowns late in the fourth quarter; the game was not decided until the final 22 seconds, when a Dallas onside kick failed. Bob Ryan, an NFL films editor, dubbed the Cowboys "America's Team" following this season, a nickname that has earned derision from non-Cowboys fans but has stuck through both good times and bad.
