Throughout the years, a number of teams in the National Football League (NFL) have either moved or merged.
In the early years, the NFL was not stable and teams moved frequently to survive, or folded only to be resurrected in a different city with the same players and owners, while the Great Depression era saw the movement of most surviving small-town NFL teams to larger cities to ensure survival, and franchise mergers were also popular during World War II in response to the exodus of players to war service. Few, if any, of these relocations and mergers were accompanied with widespread controversy.
Franchise moves became far more controversial in the late 20th century when a vastly more popular NFL, free from financial instability, allowed many franchises to abandon long-held strongholds for perceived financially greener pastures.
Despite a Pete Rozelle promise to Congress not to relocate franchises in return for a law exempting the league from certain aspects of antitrust laws, thus making possible the AFL–NFL merger, several franchises have relocated since the merger and the passage of the law (Public Law 89-800) which sanctioned it. While owners invariably cited financial difficulties as the primary factor in such moves, many fans bitterly disputed these contentions, especially in Baltimore, St. Louis, and Cleveland, each of which eventually received teams some years after their original franchises moved.
Within the United States, the San Diego–Tijuana market is currently the largest metropolitan area (and only one with over 3 million residents) without an NFL franchise. The only other city to be seriously considered in the country in recent times was San Antonio, Texas, which the Raiders seriously considered as a relocation candidate in 2014 before choosing Las Vegas.
Additionally, with the increasing suburbanization of the U.S., the building of new stadiums and other team facilities in the suburbs instead of the central city became popular in the 1970s.
The NFL considers these continuous franchises that relocated to different metropolitan areas.
The list also includes franchises from the 1960s American Football League that moved during that league's existence. The NFL and AFL agreed to merge in 1966, with the merger taking effect in 1970. All AFL franchises were accepted into the NFL, and the NFL incorporated the AFL's history, records, and statistics.
Newark Tornadoes: The Newark franchise was forfeited to the league and ordered to be disposed of to the highest bidder after the 1930 season. With no takers, the league owned-and-operated Cleveland Indians of 1931 took the Tornadoes' place, which in turn was filled by the Boston Braves (now Washington Commanders franchise) in 1932. So, while it is possible that Newark or Cleveland franchise was sold to the Boston group in 1932, there is no documentation available. The Tornadoes themselves joined the minor-league American Association later in the 1930s and adopted the name Newark Bears.
Philadelphia Eagles and Pittsburgh Steelers corporate entities and players (but not franchises) swap cities after the 1940 NFL season after complex ownership deal.
Boston Yanks franchise to New York City as the New York Bulldogs in 1949 (separate franchise but same owner and players)
Dallas Texans: operated out of Hershey, Pennsylvania for the last five games of the 1952 NFL season, playing their last three games in Akron, Ohio. Franchise folded after season's end and players awarded to new Baltimore Colts franchise in 1953
Cleveland Browns: to Baltimore as the Ravens in 1996. In 1995 Browns owner Art Modell announced plans to move the Cleveland Browns to Baltimore for the 1996 NFL season. The NFL, the city of Cleveland and Modell reached an agreement whereby the Browns franchise and history would remain in Cleveland to be resurrected by 1999. Modell was given a new franchise for Baltimore, made up of players from the 1995 Cleveland Browns. For more information on this particular move, see Cleveland Browns relocation controversy.
The Brooklyn Tigers (the same Brooklyn team that moved from Dayton in 1930) and Boston Yanks, merged initially for the 1945 season, as simply "The Yanks." The team split home games between Brooklyn and Boston. The merger became permanent, as the Boston Yanks, after relocation of the Brooklyn franchise in 1946.
New York Jets: from Manhattan (Polo Grounds) to Queens (Shea Stadium) in 1964 and to East Rutherford, New Jersey (Giants Stadium/MetLife Stadium) in 1984
The following are not actually relocations, but temporary moves because these teams' home stadiums were either under construction or otherwise adversely affected:
New York Jets: The Jets' October 21, 1973, home game vs. the Pittsburgh Steelers was moved to Three Rivers Stadium due to the New York Mets' participation in that season's World Series. Even though the Mets' last home game in the World Series was on Thursday, October 18 (Game 5), the contract between New York City, the Mets and Jets required the stadium be available for the Mets until the conclusion of their season. Game 7 of the World Series, on October 21, was at the Oakland-Alameda County Coliseum.
New York Giants: The Giants played their home games at the Yale Bowl for most of 1973 and all of 1974, and in Shea Stadium in 1975 while Giants Stadium was under construction. The Giants were left Yankee Stadium following week two of the 1973 season when the stadium in The Bronx was closed for renovations which lasted over two years.
Seattle Seahawks: Played three games in 1994 at Husky Stadium as the Kingdome was undergoing emergency repairs, and returned there for the entire 2000 and 2001 seasons before Seahawks Stadium (now Lumen Field) was completed.
The roof of the Metrodome collapsed from heavy snowfall and high winds on December 12, 2010, forcing the Vikings' home game against the New York Giants to be postponed and played on Monday, December 13 at Ford Field in Detroit. Minnesota's next home game was relocated to TCF Bank Stadium on the campus of the University of Minnesota while repairs to the roof took place.
The Vikings returned to TCF Bank Stadium for the 2014 and 2015 seasons after the Metrodome was demolished and U.S. Bank Stadium was being built on that site.
Due to a severe snow storm in late November 2014, the Buffalo Bills' home game against the New York Jets in week 12 was moved to Ford Field in Detroit. It was also postponed from Sunday, November 23 to Monday, November 24, with local markets showing the game on CBS: the Bills had already played in Detroit in 2014, defeating the Lions, 17–14, on October 5.
Another severe snowstorm in November 2022 forced the Bills' home game vs. the Browns in week 11 to be moved to Detroit, but remained on Sunday, November 20. The Bills won 31-23.
By the start of the 1920 APFA season, the nascent National Football League was composed of 15 franchises. Of those teams, only two are still in operation as of 2023[update] (denoted in bold):
Akron Pros: Changed name to Akron Indians in 1926, but shut down in 1927.
Buffalo All-Americans: Changed name to Buffalo Bisons in 1924, Buffalo Rangers in 1926, and changed back to Buffalo Bisons in 1927 before suspending operations halfway through 1927. They resumed play in 1929, but folded following the season. City is currently represented by the Buffalo Bills, a charter member of the American Football League in 1960.
Canton Bulldogs: Cleveland Bulldogs in 1923, but suspended operations in 1924, resuming play in Canton in 1925 before folding following the 1926 season. The city is currently represented by the preseason Pro Football Hall of Fame Game.
Chicago Cardinals: Merged with Pittsburgh Steelers for one year in 1944, returned as an independent team in 1945. Moved to St. Louis in 1960, and to Phoenix in 1988. Changed name to Arizona Cardinals in 1994.
Chicago Tigers: Folded following 1920 season. (The story that the Tigers lost a winner-take-all game to the Cardinals for the "rights" to Chicago is now considered a myth.)
Columbus Panhandles: Changed name to Columbus Tigers in 1923, folded following 1926 season.
Dayton Triangles: Moved to Brooklyn as Brooklyn Dodgers in 1930, changed name to Brooklyn Tigers in 1944. Merged with Boston Yanks in 1945, but folded after 1945 season. Through multiple successor franchises, the current Indianapolis Colts can trace their indirect lineage to the Triangles.[9]
Decatur Staleys: Moved to Chicago in 1921, changed name to Chicago Bears in 1922.
Detroit Heralds: Changed name to "Tigers" and folded in the middle of the 1921 season, sending its players to Buffalo. City currently represented by the Detroit Lions.
Massillon Tigers: Represented at the September 17, 1920, meeting by Ralph Hay but never played in the league and are only counted as a charter member on a technicality.
