The 1982 Miami Dolphins season was the team's seventeenth in the National Football League.
 The team was coming off an unexpected 11-4-1 1981 season and a devastating loss to the San Diego Chargers in the Divisional Round the previous season in a game dubbed the Epic in Miami.
 The Dolphins had clinched the 2 seed and were picked by many to reach the Super Bowl during the 1981 season.
 Because of the high number of picks to reach the Super Bowl the previous season, many more fans picked them to win it during the 1982 season.
 The Dolphins looked to improve on their 11-4-1 record from 1981.
 However, a players strike cancelled 7 of the team's 16 games.
 Because of this, the NFL schedule was shrunk to 9 games.
 The Dolphins started out fresh, winning their first 2 games prior to the strike.
 When season play resumed 2 months later, the Dolphins defeated the Buffalo Bills 9-7 in Buffalo to clinch a 3-0 start.
 After a loss to Tampa Bay, they defeated the Minnesota Vikings 22-14.
 The next week, they lost a brisk game against the Patriots 3-0 in a game called the Snowplow Game.
 The Dolphins would then win 3 straight games to end the season 7-2, tied for 2nd in the AFC with the Cincinnati Bengals.
 The Dolphins won 2nd place over them by virtue of a series of tiebreakers.
 In the playoffs, they defeated the Patriots in a rematch by the score of 28-13.
 They then defeated the Chargers in a rematch of the 1981 Divisional Playoffs by a score of 34-13.
 In the AFC Championship game, they shutout the Jets, 14-0 to reach the Super Bowl for the first time since 1973.
 In Super Bowl XVII, they lost to the Redskins 27-17 in a rematch of Super Bowl VII which concluded Miami's perfect 1972 season.
The 2006 Buffalo Bills season was the franchise’s 47th season as a football team, 37th in the National Football League and first under both general manager Marv Levy and head coach Dick Jauron.
 Levy, who previously coached the team from 1986-1997, leading them to four straight AFC Championships and four straight Super Bowl appearances from 1990-1993, replaced Tom Donahoe, who was fired shortly after the end of the 2005 season, with hopes that his 11 full seasons as Bills head coach would improve a franchise that failed to make the playoffs during Donahoe’s tenure.
 Jauron, who previously coached the Chicago Bears from 1999-2003, replaced Mike Mularkey, who resigned shortly after Donahoe’s firing, citing family reasons and disagreement over the direction of the organization.
 The Bills hoped to improve on their 5-11 record from 2005, while also hoping to make the playoffs for the first time since 1999, but a 30-29 loss to the Tennessee Titans eliminated the team from playoff contention, extending their playoff drought to seven straight seasons, tying a record set from 1967-1973.
 For the second consecutive season, the Bills’ opening day starting quarterback was J. P. Losman.
Second String is a direct-to-TV film from 2002 about the Buffalo Bills football team who find its first string (led by real-life Bills quarterback Doug Flutie, who had left the team by the time the film was released) out for a month after a food poisoning incident, leading the team's head coach, "Chuck Dichter" (portrayed by Jon Voight), to hire an insurance salesman named Dan Heller (played by Gil Bellows) as the team's backup quarterback.
 Teri Polo also appeared as Heller's wife; Flutie, Mike Ditka, Chris Berman, Van Miller, Bills cornerback Donovan Greer and Ken "Pinto Ron" Johnson appear as themselves.
 The film originally aired on TNT.
James Edward Kelly (born February 14, 1960) is a former American football quarterback who played in the National Football League (NFL) for eleven seasons and spent the entirety of his NFL career with the Buffalo Bills.

Super Bowl XXVI was an American football game between the National Football Conference (NFC) champion Washington Redskins and the American Football Conference (AFC) champion Buffalo Bills to decide the National Football League (NFL) champion for the 1991 season.
 The Redskins defeated the Bills by the score of 37–24, becoming the fourth team after the Pittsburgh Steelers, the Oakland Raiders, and the San Francisco 49ers to win three Super Bowls.
 The Bills became the third team, after the Minnesota Vikings (Super Bowls VIII and IX) and the Denver Broncos (Super Bowls XXI and XXII), to lose back-to-back Super Bowls.
 The game was played on January 26, 1992, at the Hubert H. Humphrey Metrodome in Minneapolis, Minnesota, the first time the city has played host to a Super Bowl (the city will host Super Bowl LII at U.S. Bank Stadium).
The Buffalo Bills were a barbershop quartet formed in Buffalo, New York, on September 20, 1947.
 The original members were tenor Vern Reed, an executive for the Tonawanda Boys' Club; lead Al Shea, who was a City of Buffalo policeman; baritone Herschel Smith, a corporate executive; and bass Bill Spangenberg, a truck driver for a steel company.
 They started out as an unnamed foursome, singing for community groups.
 During an appearance at the Buffalo Quarterback Club, they were introduced as the "Buffalo Bills", which was meant to be just for that day, but the name stuck from that point on.
 Coincidentally, a football team known formerly as the Buffalo Bisons also changed its name to the Bills at about the same time; the name proved popular enough that the current Buffalo Bills also picked up the name when they debuted thirteen years later.
Thomas Lee Agee (born February 22, 1964) is a former professional American football running back for the Seattle Seahawks, the Kansas City Chiefs, and most notably the Dallas Cowboys of the National Football League.

 The Cowboys crushed the Bills by the score of 52–17, winning their third Super Bowl in team history, and their first one in fifteen years.
 This game is tied with Super Bowl XXXVII as the second highest scoring Super Bowl ever with 69 combined points.
 The Bills became the first team to lose three consecutive Super Bowls, and just the second team to play in three straight (the Miami Dolphins played in Super Bowls VI–VIII, winning VII and VIII).
 The game was played on January 31, 1993 at the Rose Bowl in Pasadena, California, the seventh and most recent Super Bowl (until 2022 when Los Angeles hosts again) that the Greater Los Angeles Area has hosted.
Super Bowl XXVIII was an American football game between the National Football Conference (NFC) champion Dallas Cowboys and the American Football Conference (AFC) champion Buffalo Bills to decide the National Football League (NFL) champion for the 1993 season.

 The game was played on January 30, 1994, at the Georgia Dome in Atlanta, Georgia.
 Since the 1993 regular season was conducted over 18 weeks (two byes per team), the traditional bye week between the conference championship games and the Super Bowl was removed.
 This was only the third Super Bowl with only one week after that conference title games; the others were Super Bowl IV and Super Bowl XVII.
