1920–1932: Birth of the NFL
1920
The American Professional Football Association was formed on September 17, 1920, at Canton, Ohio, with Jim Thorpe elected president. 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 the season.The Massillon Tigers were represented at the September 17 meeting by Ralph Hay, but they never played in the league. As such, they are considered a charter member on a technicality.
1921
The American Professional Football Association was reorganized in Akron, Ohio on April 30, 1921, with Joe F. Carr elected as new league president. With the low entry barrier of a $100 membership fee, the number of teams ballooned to 21. Four of these franchises would last only one season, with Tonawanda Kardex only making it through a single game. Three other franchises folded mid-season.

As America became more deeply embroiled in World War II, the Cleveland Rams suspend operations for the 1943 season due to a major loss of players. The Philadelphia Eagles and Pittsburgh Steelers were able to work around the player shortage by merging to form the "Phil-Pitt Steagles."The size of the active roster reduced from 33 to 28 players per team. Intent of this reduction was to appease the Office of Defense Transportation by reducing the impact of travel by road teams. Additionally, teams primarily used day coaches rather than sleeper cars, a more efficient, albeit less comfortable mode of travel. This continued through the 1944 season.
