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.
1978 Dallas Cowboys season
Later that same season, they met the Rams again in the NFC Championship match. Both teams entered the game with a 12-4 regular season record. Both teams dominated their first round playoff opponents, which included a Rams 34-10 blowout victory at home over their other long time playoff nemesis, the Minnesota Vikings. And now, because of that emotionally charged week-3 loss to the Rams, the Cowboys were forced to play for the NFC Championship on the road in Los Angeles, California - in order to give themselves the chance to defend their Super Bowl title in Miami against the Pittsburgh Steelers, who had already won the AFC Championship against the Houston Oilers earlier that same day. But, as far as the Rams and their fans were concerned, the Cowboys would never get that chance because this was definitely going to be the year the Rams finally got over the hump, and became "this years champions".
