Document 7: 2015 Buffalo Bills season: The 2015 Buffalo Bills season was the franchise’s 56th overall season as a football team, 46th in the National Football League, third under leadership of general manager Doug Whaley and first under new head coach Rex Ryan, who signed a five-year, $27.5 million contract on January 12, 2015 after having previously spent the past six seasons coaching the division-rival New York Jets, leading them to two straight AFC Championship games in 2009 and 2010, becoming the franchise’s 18th head coach and the fifth in the past seven years in the process. Ryan replaced Doug Marrone, who opted out of his contract on December 31, 2014 to take advantage of a contract loophole, fearing the Pegulas were going to fire him, hence the reason the Bills entered the 2015 season looking for a new head coach. Despite the bold prediction made by Ryan at his introductory press conference, where he stated, “I’m not going to let our fans down. I am not going to do that. I know it’s been 15 years since the Bills made the playoffs. Well, get ready, man, we’re going. We are going,” the Bills were unable to make the playoffs in their first season with Ryan as head coach, finishing with a record of 8-8 (the team’s first since 2002), making it the 16th straight season without a playoff appearance, which became the longest active in major professional sports after Major League Baseball’s Toronto Blue Jays broke their 22-year playoff drought on September 25, 2015. It was also the first full season under the ownership of Terry and Kim Pegula (whom also own the Buffalo Sabres), having purchased the Bills partway through 2014 after the death of longtime owner Ralph Wilson in March at the age of 95. The Bills began their season with an open competition for the starting quarterback position after Kyle Orton, the starter for most of the 2014 campaign, retired during the offseason, so the team acquired free agent Tyrod Taylor, a former backup quarterback of the Baltimore Ravens, who won the competition over incumbent second-string quarterback EJ Manuel and trade acquisition Matt Cassel, the latter of whom the team later traded along with a seventh-round pick in 2017 to the Dallas Cowboys, in exchange for a fifth-round draft pick in 2017.

Document 9: 2006 Buffalo Bills 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.
Document 10: 2016 Buffalo Bills season: The 2016 Buffalo Bills season was the franchise’s 57th overall season as a football team, 47th in the National Football League, fourth under leadership of general manager Doug Whaley and second under head coach Rex Ryan. The Bills hoped to improve on their 8-8 record from 2015, the team’s first since 2002, but a 34-31 overtime loss to the Miami Dolphins in Week 16 eliminated the Bills from playoff contention for a 17th-straight season, extending the longest active drought among all four North American major professional sports leagues. It would be Rex’s final season as head coach of the Bills, as he and his twin brother, Rob, were fired with one game remaining in the regular season.
Document 11: 2010 Buffalo Bills season: The 2010 Buffalo Bills season was the team's 41st season in the National Football League and their 51st overall. It was Buffalo's first season with Buddy Nix in the role of general manager and head coach Chan Gailey. The Bills hoped to improve on their 6–10 record from the 2009 season, and attempt to make the playoffs for the first time since 1999, the longest standing playoff drought in the NFL. The Bills had the 9th pick in the first round of the 2010 NFL Draft selecting C. J. Spiller, a running back from Clemson. This season marks the first 0–8 start since 1984, in which they finished 2-14. They were eliminated from playoff contention in Week 12, extending their playoff drought to 11 seasons. Despite the poor start, Buffalo became largely competitive after the bye in Week 9. Their next four losses were by only three points each, all to teams that made the playoffs in 2011—Baltimore, Kansas City, Chicago and Pittsburgh (three of these losses went to overtime). The Bills eventually won four of their final eight games, which carried over into a strong start to the 2011 season. The 2010 season was marked by the emergence of wide receiver Stevie Johnson, who gained 1,073 receiving yards and nose tackle Kyle Williams, an All-Pro in 2010 who gained status as an elite defensive tackle.

The Bills were unable to improve upon their third consecutive 7–9 regular season record (2006, 2007 and 2008) and failed to make the playoffs for the 10th consecutive year, the longest standing playoff drought in the NFL. Dick Jauron returned as head coach for a fourth season, the first Bills coach since Marv Levy to receive a contract extension beyond three years. He was fired on November 17 after a 3–6 start and replaced on an interim basis by defensive coordinator Perry Fewell, who was fired at the end of the season, but not before starting Ryan Fitzpatrick for the rest of the season.
