Context: The New York Giants are a professional American football team based in the New York metropolitan area.  The Giants compete in the National Football League (NFL) as a member club of the league's National Football Conference (NFC) East division.

The Dallas Cowboys are a professional American football team based in the Dallas–Fort Worth metroplex.  The Cowboys compete in the National Football League (NFL) as a member club of the league's National Football Conference (NFC) East division.  The team is headquartered in Frisco, Texas, and plays its home games at AT&T Stadium in Arlington, Texas, which opened for the 2009 season.  The stadium took its current name prior to the 2013 season.  The Cowboys joined the NFL as an expansion team in .  The team's national following might best be represented by its NFL record of consecutive sell-outs.  The Cowboys' streak of 190 consecutive sold-out regular and post-season games (home and away) began in 2002.  The franchise has made it to the Super Bowl eight times, tied with the Pittsburgh Steelers, and the Denver Broncos for second most Super Bowl appearances in history, just behind the New England Patriots record nine Super Bowl appearances.  This has also corresponded to eight NFC championships, most in the NFC.  The Cowboys have won five of those Super Bowl appearances, tying them with their NFC rivals, the San Francisco 49ers, and the AFC's Patriots; all three are second to Pittsburgh's record six Super Bowl championships.  The Cowboys are the only NFL team to record 20 straight winning seasons (1966–85), in which they only missed the playoffs twice (1974 and 1984), an NFL record that remains unchallenged.

The Bills conduct summer training camp at St. John Fisher College in Pittsford, New York, an eastern suburb of Rochester, New York. The New York Giants season was the franchise's 88th season in the National Football League, the ninth under head coach Tom Coughlin and the third playing their home games at MetLife Stadium in East Rutherford, New Jersey.  The Giants began the 2012 season as defending Super Bowl Champions for the fourth time in their history, by virtue of their 21–17 victory in Super Bowl XLVI over the New England Patriots.  The Giants finished 9–7 for the second straight year, but failed to make the playoffs.

The Chicago Tigers of the American Professional Football Association (APFA) played only in the first year of the league (1920) and, because of this, have the distinction of being the first NFL team to fold.  They had a record of 2 wins, 5 losses and 1 tie.  The team played its home games at Chicago's Wrigley Field (then called Cubs Park) and was the first NFL team to do so.  The Tigers were never formally members of the APFA.  However, since the team played seven games against APFA teams in 1920, resulting in a 1–5–1 league record, they are generally included in the league standings.
