The 1970 NFL season was the 51st regular season of the National Football League, and the first one after the consummation of the AFL–NFL merger. The merged league realigned into two conferences: all 10 of the former AFL teams joined the Baltimore Colts, Cleveland Browns, and Pittsburgh Steelers to form the American Football Conference; while the other 13 NFL clubs formed the National Football Conference. The season concluded with Super Bowl V when the Baltimore Colts beat the Dallas Cowboys at the Orange Bowl in Miami, Florida. The Pro Bowl took place on January 24, 1971, where the NFC beat the AFC at the Los Angeles Memorial Coliseum. Merger between NFL and AFL The merger forced a realignment between the combined league's clubs. During the previous 1969 season, there were 16 NFL teams and 10 AFL teams: Because there were more NFL teams than AFL teams, three teams needed to be transferred to balance the two new conferences at 13 teams each. In May 1969, the Baltimore Colts, Cleveland Browns, and the Pittsburgh Steelers agreed to join all ten AFL teams to form the American Football Conference (AFC). The remaining NFL teams formed the National Football Conference (NFC). Replacing the old Eastern and Western conferences (although divisions from those conferences still existed but were renamed to suit the realignment), the new conferences, AFC and NFC, function similar to Major League Baseball's American and National leagues, and each of those two were divided into three divisions: East, Central, and West. The two Eastern divisions had five teams; the other four divisions had four teams each. The realignment discussions for the NFC were so contentious that one final plan, out of five of them, was selected from an envelope in a vase by Commissioner Pete Rozelle's secretary, Thelma Elkjer on January 16, 1970. The format agreed on was as follows: This arrangement would keep most of the pre-merger NFL teams in the NFC and the AFL teams in the AFC. Pittsburgh, Cleveland, and Baltimore were placed in the AFC in order to balance the conferences, while the NFC equalized the competitive strength of its East and West divisions rather than sorting out teams purely geographically. Division alignment in 1970 largely kept traditional rivals in the same division. Plans were also made to add two expansion teams, but this would not take place until 1976, seven years after the merger, when the Tampa
