Context paragraphs:
2009 New York Giants season: The 2009 New York Giants season was the 85th season for the team in the National Football League.  It was the team's final season in Giants Stadium; In 2010, the Giants moved into New Meadowlands Stadium.  The Giants hoped to improve upon their 12–4 record, avenge their divisional round loss to the Philadelphia Eagles and make the playoffs for the fifth straight year.  Despite starting 5–0 to begin the season, they went 3–8 in their next 11 games and finished 3rd in the NFC East.  They were eliminated from playoff contention in Week 16.  They played teams from the NFC South and AFC West as per the schedule rotation, as well as their regular games with their NFC East rivals.  For head coach Tom Coughlin, this was his 6th season as the coach of the Giants.

New Jersey Generals: The New Jersey Generals was a franchise of the United States Football League (USFL) established in 1982 to begin play in the spring and summer of 1983.  The team played three seasons from 1983–85, winning 31 regular-season games and losing 25 while going 0–2 in postseason competition.  Home games were played at Giants Stadium in East Rutherford, New Jersey, which was called The Meadowlands for Generals games.

1985 New York Giants season: The 1985 New York Giants season was the 61st season for the club in the National Football League (NFL).  The Giants entered the season looking to improve on their 9–7 record in 1984, which was enough to qualify the team for the playoffs as the second wild-card team, and to return to the playoffs for the second consecutive year under third-year head coach Bill Parcells.  The Giants managed to do both, finishing with 10 victories for the first time since 1963 when the team won 11 games and finishing as the first wild-card team which earned the Giants a home playoff game at Giants Stadium.  They defeated the San Francisco 49ers 17–3 in that game, avenging their loss to the 49ers in the previous year's divisional playoffs.  However, it was as far as the Giants could get as they were defeated by the eventual Super Bowl champion Chicago Bears in the divisional round at Soldier Field 21–0.  Bill Parcells stated in "America's Game: 1986 Giants" that the game the Giants played against the Bears in the playoffs that "an honest evaluation of it, we could have probably beat that team one out of ten times.  But that day was one of the days that that could have happened", the Giants were ultimately undone by a whiffed punt from legend Sean Landeta, the ball flew out of the air when he went to punt it from a burst of wind coming of Lake Michigan, the Bears recovered the ball for a touchdown from less than 5 yards from the end zone, and ended up winning 21-0.  At the time, the team set a record for most rushing yards in one season by a Giants team.

J. Walter Duncan: J. Walter Duncan Jr. (November 26, 1916 – February 21, 2009) was an American businessman.  He was born in Illinois, but moved to Oklahoma in 1949.

List of Green Bay Packers stadiums: The Green Bay Packers have played home games in eight stadiums since their establishment as a professional football team in 1919.  Their first home was Hagemeister Park, where they played from 1919 to 1922, including their first two seasons in the National Football League (NFL).  Hagemeister Park was a park owned by the Hagemeister brewery; during games ropes were set-up around the field and attendees either walked up or parked their cars nearby and used them for seats.  After the first season, a small grandstand was built and the field was fenced off.  Green Bay East High School was built at the location of Hagemeister Park in 1922, which forced the Packers to move to Bellevue Park, a small minor league baseball stadium that seated 5,000.  They only played for two seasons at Bellevue Park before moving to City Stadium in 1925.  Although City Stadium was the Packers' official home field, in 1933 they began to play part of their home schedule in Milwaukee to attract more fans and revenue.  After hosting one game at Borchert Field in 1933, the Packers played two or three home games each year in Milwaukee, at Wisconsin State Fair Park from 1934 to 1951 and at Marquette Stadium in 1952.  The games were moved to Milwaukee County Stadium after it opened in 1953 and continued through 1994, after which the Packers moved back to Green Bay permanently.

1977 New York Jets season: The 1977 New York Jets season was the 18th season for the team and the 8th in the National Football League.  It began with the team trying to improve upon its 3–11 record from 1976 under new head coach Walt Michaels and beginning the post-Joe Namath era.  However, the Jets struggled with their third consecutive 3-11 season.  They won a major off the field court decision.  As per the memorandum of understanding signed in late 1961 by team original owner (as the New York Titans) Harry Wismer, Shea Stadium's co-tenants, the New York Mets, would have exclusive use of the stadium until they had completed their season.  The Jets were, in most years, required to open the season with several road games, a problem made worse in 1969 and 1973 when the Mets had long playoff runs.  Feeling that this arrangement was a disadvantage, the team announced in 1977 that they would play two home games a year during the month of September at the Giants' new home in New Jersey, Giants Stadium.  Litigation began between New York City and the Jets over the issue, and in the lawsuit's settlement, the city agreed to allow the Jets to play two September home games a season at Shea beginning in 1978 for the remaining six years in the Jets' lease.  In 1977, the Jets were to play one September game at Giants Stadium and an October 2 game at Shea.  From 1967 through this season—a span of 11 seasons—the Jets did not play a home game at Shea Stadium in the month of September.  As of 2017, the Jets are the first (and so far, only) team in NFL history to finish 3 straight seasons with only 3 wins.  Since the NFL schedule expanded to 16 games in 1978, no team has finished 3-13 3 years in a row.

New York Cosmos (1970–85): The New York Cosmos (simply the Cosmos in 1977–1978) was an American professional soccer club based in New York City and its suburbs.  The team played home games in three stadiums around New York before moving in 1977 to Giants Stadium, East Rutherford, New Jersey, where it remained for the rest of its history.  Founded in 1970, the team competed in the North American Soccer League (NASL) until 1984 and was the strongest franchise in that league, both competitively and financially – based largely around its backing by Warner Communications President Steve Ross, which enabled it to sign internationally famous stars such as the Brazilian forward Pelé, Italian striker Giorgio Chinaglia and the West German sweeper Franz Beckenbauer.  The acquisition of these foreign players, particularly Pelé, made the Cosmos into what Gavin Newsham called "the most glamorous team in world football", and contributed to the development of soccer across the United States, a country where it had previously been largely ignored.

1984 New York Jets season: The 1984 New York Jets season was the 25th season for the team and the 15th in the National Football League.  It began with the team trying to improve upon its 7–9 record from 1983 under head coach Joe Walton.  After playing the previous 20 seasons at Shea Stadium in Queens, 1984 marked their first season of playing its home games at Giants Stadium in The Meadowlands, which was also the home of the NFC's New York Giants.  Mark Gastineau made NFL history by recording 22 sacks, to establish a then new official single season record.  The Jets finished the season with a record of 7–9.

Hartford Colonials: The Hartford Colonials, originally the New York Sentinels, were a professional American football team that played in the United Football League in its 2009 and 2010 seasons.  A charter member of the UFL, the Sentinels began play in 2009 nominally representing New York City but playing its home games in three stadiums, none of which were in the city proper: Rentschler Field in East Hartford, Connecticut; Shuart Stadium in Hempstead, New York (on Long Island); and the now-demolished Giants Stadium in East Rutherford, New Jersey.  (The Sentinels had scheduled a game for Citi Field in Queens but relocated that game to Long Island.)  As the Colonials, the team played all of its home games at Rentschler Field in East Hartford, representing the adjacent city of Hartford.  League-wide financial problems and the high rate of rent at "The Rent" led to the league suspending the Colonials' operations in August 2011, a month before it would have begun play in its third season.  The league had stated that the Colonials could be brought back for the 2012 UFL season, if it were to be played, but the announcement of the 2012 season removed Hartford's logo (which had remained on the site in 2011, with indication it had been suspended) from the UFL Web site and did not include the team in the league's 2012 schedule.

1973 New York Giants season: The 1973 New York Giants season was the 49th season for the club in the National Football League.  The season saw the Giants attempting to improve on their 8-6 record from 1972.  However, the Giants suffered one of the worst seasons in franchise history, winning only 2 games, while losing 11, and tying a game.  The 2 wins were against the Houston Oilers and the St. Louis Cardinals while the tie was against archrival Philadelphia, in what turned out to be the last game the Giants would ever play at Yankee Stadium before playing their final 5 home games at the Yale Bowl in Connecticut.  They moved to Shea Stadium in 1975 and to Giants Stadium in 1976.  The 2 wins by the Giants equalled the second fewest the team had ever posted in any season and it was their worst season since a 1-12-1 record in 1966.  After the season, head coach Alex Webster was fired and replaced the following season by Bill Arnsparger.
