Things were not always great for the NFL - it was coming together to make it work that brought it to where it is today
The early National Football League (NFL) experienced significant struggles, as it was poorly organized, underfunded, and unstable, characterized by numerous teams quickly joining and leaving, low fan attendance, and intense competition for players. Pro football also struggled for recognition, overshadowed by more popular sports
The creation of the NFL in 1920 was an attempt by owners to establish a strong, stable league that could control player salaries and finances more effectively.
It wasn't until 1936 that an NFL season began with the same lineup of teams as the previous year, marking a significant step toward stability.
