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.
Super Bowl LIII
The Patriots are making their third consecutive Super Bowl appearance, their fourth in five years, their record 11th overall, and ninth under the Belichick–Brady head coach–quarterback tandem; the Patriots are also the first team to play in three consecutive Super Bowls since the Buffalo Bills played in four straight from Super Bowl XXV through Super Bowl XXVIII. The Patriots are only the third team overall to play in three consecutive Super Bowls, after the aforementioned Bills and the 1971–73 Miami Dolphins. The Rams are making their fourth Super Bowl appearance in franchise history, their first appearance in the Super Bowl since moving back to Los Angeles in 2016, and their first as a franchise since Super Bowl XXXVI.
