History and League Success
The Falcons entered the league as an expansion team in 1966. Both the NFL and the AFL were heavily interested in placing a team in Atlanta (both leagues had sponsored preseason games in the city), ultimately the NFL forced Atlanta (the city) to decide on a league; it chose the NFL.
The Falcons have generally been mediocre in their history; they have only made two Super Bowl appearances (1999 and 2017; the 2017 appearance was notable for the team's total collapse after holding a 28-3 lead late in the third quarter against the New England Patriots, ultimately losing 28-34 in the only overtime game in Super Bowl history).
