Football is one of the biggest sports on the planet and since the early days of the NFL many decades ago now, there has been demand from areas that don’t have a team to get one. These are called expansion teams and while there hasn’t been one in more than 20 years, there are currently talks from league owners to expand again, perhaps even to "international" cities such as London or Toronto.
With talk going on about which cities would be best suited for an expansion team, we decided to take a look back at the history of expansion teams in the league since 1960, which is when "America's Team" joined the party. The Dallas Cowboys were joining a league that featured the following teams: The St. Louis Cardinals (who had just moved from Chicago), Cleveland Browns, New York Giants, Philadelphia Eagles, Pittsburgh Steelers, Washington Redskins (now the Commanders), Baltimore Colts, Chicago Bears, Detroit Lions, Green Bay Packers, Los Angeles Rams and San Francisco 49ers.
