The 1970 NFL season was the 51st regular season of the National Football League, and the first one after the AFL-NFL Merger. The merger forced a realignment between the combined league's clubs. Because there were 16 NFL teams and 10 AFL teams, three teams needed to transfer 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 the final plan was selected from a vase in January 1970. The format agreed on was as follows: NFC East: Dallas, New York (Giants), Philadelphia, St. Louis, Washington NFC Central: Chicago, Detroit, Green Bay, Minnesota NFC West: Atlanta, Los Angeles, New Orleans, San Francisco AFC East: Baltimore, Buffalo, Miami, Boston, New York (Jets) AFC Central: Cincinnati, Cleveland, Houston, Pittsburgh AFC West: Denver, Kansas City, Oakland, San Diego This arrangement would keep most of the pre-merger NFL teams in the NFC conference and the AFL teams in the AFC. Pittsburgh, Cleveland, and Baltimore were placed in the AFC in order to balance it out, while the NFC equalized the competitive strength of its East and West divisions rather than sorting out teams just geographically. Prior to 1966, the NFL had two seven-team conferences: Eastern Conference: Cleveland, Dallas, New York, Philadelphia, Pittsburgh, St. Louis, and Washington Western Conference: Baltimore, Chicago, Detroit, Green Bay, Los Angeles, Minnesota, and San Francisco. Atlanta was added as an expansion franchise in 1966 and placed in the Eastern Conference. Every team had a bye week during the 1966 season. When New Orleans was awarded an expansion franchise for 1967, the NFL divided its teams into two eight-team conferences, with two four-team divisions in each conference as follows: Eastern Conference/Capitol Division: Dallas, New Orleans, Philadelphia, and Washington Eastern Conference/Century Division: Cleveland, New York, Pittsburgh, and St. Louis Western Conference/Central Division: Chicago, Detroit, Green Bay, and Minnesota Western Conference/Coastal Division: Baltimore, Atlanta, Los Angeles, San Francisco. The Giants and Saints swapped divisions in 1968, and then returned to the 1967 alignment in 1969. Meanwhile, the AFL for its 10-year existence had: Eastern Division: Boston, Buffalo, Houston, and New York (with Miami added in 1966) Western Division: Dallas/Kansas City, Denver, Los Angeles/San Diego, and Oakland (with Cincinnati added in 1968). Division alignment in 1970 was largely intended to preserve the pre-merger setups, keeping 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. The 26-team league began to use an eight-team playoff format, four from each conference, that included the three division winners and a wild card team, the second-place team with the best record. The season concluded with the Colts defeating the Dallas Cowboys 16–13 in Super Bowl V, the first Super Bowl played for the NFL Championship. The game was held at the Orange Bowl in Miami, and was the first Super Bowl played on artificial turf. Seven teams played their home games on artificial turf in 1970. This was up from 2 teams in both the NFL and AFL in 1969. The teams were: Cincinnati, Dallas, Houston, Miami, Philadelphia, Pittsburgh and St. Louis. Cincinnati and Pittsburgh opened new stadiums: Riverfront Stadium and Three Rivers Stadium. To televise their games, the combined league retained the services of CBS and NBC, who were previously the primary broadcasters of the NFL and the AFL, respectively. It was then decided that CBS would televise all NFC teams (including playoff games) while NBC all AFC teams. For interconference games, CBS would broadcast them if the visiting team was from the NFC and NBC would carry them when the visitors were from the AFC. At the time, all NFL games were blacked out in the home team's market, so this arrangement meant that fans in each team's home market would see all of their team's televised Sunday afternoon games on the same network (CBS for NFC teams and NBC for AFC teams). The two networks also divided up the Super Bowl on a yearly rotation. Meanwhile, with the debut of ''Monday Night Football'' on ABC September 21, 1970, the league became the first professional sports league in the United States to have a regular series of nationally-televised games in prime-time, and the only league ever to have its games televised on three major broadcast networks at the same time. Both teams that advanced to the Super Bowl, the Baltimore Colts and the Dallas Cowboys, had suffered humiliating defeats at home on Monday Night Football during the season. The Chicago Bears' first home game of the season against the Philadelphia Eagles was played at Northwestern University's Dyche Stadium because the Chicago Cubs did not want to convert Wrigley Field, which they then shared with the Bears, to a football configuration while the Cubs were still in playoff contention. The Bears also treated this game as a trial run for possibly moving their home games to Evanston. Before the season, the league demanded that the Bears find a new home field because the seating capacity of Wrigley Field was too small (after the merger, all stadiums were required to seat at least 50,000), and Wrigley Field did not have lights, making it unavailable for late afternoon and night games. Ultimately, a deal to make Dyche Stadium the Bears' new home fell through, and negotiations with the Cubs' ownership for continued use of Wrigley Field also collapsed. As a result, the Bears moved to Soldier Field in 1971 where they remain to the present day, save for a temporary relocation in 2002 to the University of Illinois' Memorial Stadium while Soldier Field was completely renovated. On November 8, New Orleans Saints placekicker Tom Dempsey kicked a record 63-yard field goal. The record stood for 43 years (tied in 1998, 2011 and 2012) until it was broken in by Denver Broncos' Matt Prater. The Denver Broncos, Detroit Lions, and Los Angeles Rams all started 3–0 but lost in Week Four. Only the Lions would go on to the playoffs after the 3–0 start. ==Major rule changes== *The NFL rules became the standardized rules for the merged league, which included dropping the AFL's two-point conversion. This would not be reinstated until 1994. *The stadium's scoreboard clock became the official game clock, an AFL innovation. *Rules were added to place last names on the back of players' jerseys. The AFL had had names on jerseys; the pre-merger NFL teams had not. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1970 NFL season」の詳細全文を読む スポンサード リンク
