The 1966 NFL season was the 47th regular season of the National Football League, and the season after which was played Super Bowl I, though it was called the AFL-NFL World Championship Game. The league expanded to 15 teams with the addition of the Atlanta Falcons. This was the last season that the NFL had just two divisions, and that the conference champions went directly to the NFL Championship Game without playing in playoff games.league awarded an expansion franchise to the city of Atlanta on June 30, 1965. NFL Commissioner Pete Rozelle granted ownership of the Atlanta Falconsto Rankin Smith Sr.. The Falcons were awarded the first pick in the 1966 NFL Draft, as well as the final pick in each of the first five rounds. The league also provided the Falcons with an expansion draft six weeks later.
Thus, after the Green Bay Packers defeated the Dallas Cowboys in the NFL Championship Game, they then went on to beat the American Football League's Kansas City Chiefs in the first annual AFL-NFL World Championship Game (later known as Super Bowl I).
In the Eastern Conference, the St. Louis Cardinals and Dallas Cowboys were unbeaten through Week Six, when they played to a 10-10 tie. Both teams won their next two games, with St. Louis's 6-1-1 better than Dallas at 5-1-1. In Week Nine (November 6), St. Louis beat the Giants, 20-17, while Dallas came up short in a 24-23 loss to the Eagles. The next week, Dallas won at Washington 31-30 on a field goal with 0:15 left, while the Cards fell at Pittsburgh, 30-9, cutting their safety margin to a game ahead. St. Louis had a bye in Week Eleven, and a 20-7 Dallas victory over Pittsburgh gave the Cards and Cowboys records of 7-2-1. Both teams won the next week, setting up the stage for their December 4 meeting in Dallas during Week Thirteen. The Cards took a 10-7 lead in the first quarter, but Dallas won 31-17 to take over the conference lead. In Week Fourteen, Dallas hosted Washington, and lost 34-31 on a field goal at 0:08. The Cardinals were in a must-win game against what should have been an easy opponent, the new (2-10-0) Atlanta Falcons. Instead, the Falcons notched their third win and virtually ended St. Louis's hopes to go to the title game. The St. Louis Cardinals, who lost again the next week, never got that close to the Super Bowl again; they would move to Phoenix twenty years later.
