Joseph Frank Walton (born December 15, 1935) is a former American football player and coach who most recently retired after 20 years as the head football coach and creator of the football program at Robert Morris University.
 Walton played eight seasons in the National Football League (NFL) as a pass catching tight end for the Redskins and Giants.
 He served as head coach of the New York Jets for seven seasons, guiding them to the playoffs twice.
 He has also served as an assistant coach for the New York Giants, the Washington Redskins, the New York Jets and the Pittsburgh Steelers during a 20-year period.
The Cowboys–Giants rivalry is a National Football League (NFL) rivalry between the Dallas Cowboys and New York Giants.
 The beginning of this rivalry is difficult to trace, but is perhaps best defined by the first game the two teams ever played back in 1960, which resulted in a 31–31 tie.
 In the early 1960s the New York Giants were beginning to wind down as an NFL powerhouse.
 After having been arguably the most dominant team in the Eastern Conference through the 1950s and early 1960s the Giants entered a period of poor play where they did not make the playoffs from 1964–81.
 While the Giants dominated the Cowboys in the first few years of the rivalry, the Cowboys picked up steam and took control from the mid-1960s to the early 1980s, winning 17 of the 20 meetings between the 2 teams in the 1970s.
 In the 1980s however the Giants struck back, and the rivalry has been relatively even handed ever since with intermittent spurts of dominance (the Giants in the late 1980s and the Cowboys in the early 1990s).
 This is a unique rivalry in American sports in that no other Texas area team is in the same division as a New York area team, or has a consistent rivalry with one, most likely due to the relatively far geographical distance between the two regions (though during the 1960s, the New York Jets were division rivals with the Houston Oilers in the American Football League East Division).
The 2016 season was the New York Giants' 92nd season in the National Football League, their seventh playing their home games at MetLife Stadium and the first under head coach Ben McAdoo.
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.
The 2007 New York Giants season was the 83rd season for the New York Giants in the National Football League.
 The Giants finished the regular season 10–6 and in second place in the NFC East, improving upon their 8–8 record in 2006 in which they finished third in their division.
 They qualified for the playoffs as a wild-card team as the #5 seed, and beat the #4 seed Tampa Bay Buccaneers (9–7), the top-seeded Dallas Cowboys (13–3), and the #2 seed Green Bay Packers (13–3) to become the National Football Conference representative in Super Bowl XLII.
 There, they defeated the heavily favored and previously undefeated 18–0 New England Patriots and spoiled their perfect season.
 The 2007 New York Giants became the 9th wild card team in NFL history to reach the Super Bowl and the 5th wild card team to win the Super Bowl, and the very first NFC wild card to accomplish the feat.
 They were the third team in history to win three road playoff games en route to a Super Bowl and set a league record for most consecutive road wins in a single season (11), though the Super Bowl is played on a neutral field rather than an opponent's stadium.
 It was the 7th league championship season for the New York Giants and their first since they won Super Bowl XXV in 1991.
Benjamin Lee "Ben" McAdoo (born July 9, 1977) is an American football coach who is the head coach of the New York Giants of the National Football League (NFL).
The New York Giants (informally known as Brickley's Giants and Brickley's New York Giants) were a professional American football team with the American Professional Football Association (now the National Football League) whose only season played was in 1921.
 The team has also been referred to as the Brooklyn Giants and Brickley's Brooklyn Giants.
 The Brickley's Giants were the first of 17 professional football teams to represent New York City at one time or another.
 The team was founded in 1919 by Charles Brickley, who received All-American honors while at Harvard.
 Brickley's Giants played two games in their only season, losing to the Buffalo All-Americans, 55–0, and the Cleveland Tigers, 17–0.
 It was the second-shortest-lived franchise in NFL history, behind only the Tonawanda Kardex, who played only one game in the same 1921 season.
Duane Charles "Bill" Parcells (born August 22, 1941), also known as The Big Tuna, is a former American football coach, best known as a head coach in the National Football League (NFL) for 19 seasons.

 Parcells later served as the head coach of the New England Patriots, New York Jets, and Dallas Cowboys.
 Throughout his career, he coached teams that were in a period of decline and turned them into postseason contenders.
 He is the only coach in NFL history to lead four different teams to the playoffs and three different teams to a conference championship game.
