1920–1931: Before the playoffs
1920
The American Professional Football Association is formed. The fourteen teams were mainly drawn from the Ohio League, Chicago Circuit, New York Pro Football League and other teams from the lower midwest. A $100 membership fee was charged. The Chicago Tigers folded after season.[1]
A new and distinct Cleveland Indians franchise was formed. Two other teams joined the NFL, the Duluth Kelleys and the St. Louis All Stars. The St. Louis team folded after one season.
Before the season, the owner of the Cleveland Indians bought the Canton Bulldogs and "mothballed" it, taking the team's nickname and players to Cleveland for the season. The Canton Bulldogs had won the NFL championship in 1923, and won it again as the Cleveland Bulldogs in 1924.
Prior to the season, the league decided to eliminate the financially weaker teams. As a result, the league dropped from 22 to 12 teams, and a majority of the remaining teams were centered around the East Coast instead of the Midwest, where the NFL had started. The New York Yankees were added from the American Football League and the Cleveland Bulldogs returned.
The NFL drops to ten teams. Two teams had folded, the Buffalo Bisons sat out the season and the Cleveland Bulldogs moved and played as the Detroit Wolverines.
The league increased back to 12 teams with the addition of two franchises, the Staten Island Stapletons, and the Orange Tornadoes. Two mothballed teams activated for the season. Minneapolis re-entered as the Red Jackets and the re-entry of the Buffalo Bisons.
Prior to the season, Brooklyn businessmen William B. Dwyer and John C. Depler bought the Dayton Triangles, moved it, and renamed it the Brooklyn Dodgers. The Orange Tornadoes relocated to Newark. The Portsmouth Spartans entered as a new team.
The league decreased to 10 teams due to financial hardships caused by the Great Depression. While the Cleveland Indians joined as an expansion team, the league lost the Minneapolis Red Jackets and the Newark Tornadoes. Even the Frankford Yellow Jackets had to fold midway through the season.
Houston Oilers announce that they will move to Nashville and are renamed the Tennessee Oilers. They play the 1997 season in Memphis and the 1998 season at Vanderbilt Stadium in Nashville while a new stadium is built in Nashville.
