full_context: Document 1: 2016 Miami Dolphins season: The 2016 Miami Dolphins season was the franchise's 47th season in the National Football League, the 51st overall and the first under head coach Adam Gase. The season saw the Dolphins trying to improve upon their 6–10 record from 2015. After a sluggish 1–4 start, the Dolphins would claim six straight wins, and finish the season on a 9–2 run. With their Week 15 win over the New York Jets, the Dolphins clinched a winning record for the first time since 2008, and clinched a playoff berth the following week after the Kansas City Chiefs defeated the Denver Broncos. They were also the first AFC East team, other than the New England Patriots, to qualify for the postseason since the New York Jets did so in 2010. However, they were defeated by the Pittsburgh Steelers in the Wild Card round, ending their season.
Document 2: 2011 Miami Dolphins season: The Miami Dolphins season was the team's 42nd season in the National Football League, the 46th overall and the fourth under head coach Tony Sparano. The Dolphins made their first round selection with the 15th pick of the 2011 NFL Draft on Florida offensive lineman Mike Pouncey. The team got off to an 0–7 start and won six of their final nine games, but failed to improve on their record from 2010, resulting in Sparano being fired on December 12, 2011.
Document 3: 2017 Miami Dolphins season: The 2017 Miami Dolphins season is the franchise's 48th season in the National Football League, the 52nd overall and the second under head coach Adam Gase.
Document 4: 2015 New York Jets season: The New York Jets season was the franchise's 46th season in the National Football League and the 56th overall. The team improved on their 4–12 record in 2014 under former head Coach Rex Ryan. Under new head coach Todd Bowles, they succeeded in matching their record in just five games, starting 4–1. Prior to the season, the Jets made a number of moves, including, re-acquiring Darrelle Revis and Antonio Cromartie, two cornerbacks who were instrumental in the Jets previous defensive success, and obtaining Ryan Fitzpatrick and Brandon Marshall in trades. The team retrogressed to 5–5, before going on a five-game winning streak, clinching their first winning season since 2010. However, it wasn't enough to make the playoffs, as they lost to the Buffalo Bills in Week 17 and the Pittsburgh Steelers defeated the Cleveland Browns. The Steelers and Jets both finished 10–6, but the Steelers clinched the final AFC playoff spot over the Jets based on a better record vs. common opponents. The Jets finished the season as the league's only team with a winning record to not make the playoffs.
Document 5: 2008 Miami Dolphins season: The 2008 Miami Dolphins season was the organization's 39th season in the National Football League and 43rd overall. During the regular season the Dolphins completed the greatest single-season turnaround in NFL history, going from a 1–15 regular season record in 2007 to an 11–5 record in 2008. The previous record for most improved team one year after a 1–15 season belonged to the 1992 Indianapolis Colts, who went 9–7. The 1999 Indianapolis Colts were the only other team to accomplish a 10-game turnaround, winning 13 games after winning 3 in 1998. Additionally, Miami won the AFC East, becoming the first team in NFL history to win their division after only having one win the previous season.
Document 6: 2015 Miami Dolphins season: The 2015 Miami Dolphins season was the franchise's 46th season in the National Football League and the 50th overall.

Document 7: 1997 Indianapolis Colts season: The 1997 Indianapolis Colts season was the 45th season for the team in the National Football League and 14th in Indianapolis. The Indianapolis Colts finished the National Football League's 1997 season with a record of 3 wins and 13 losses, and finished fifth in the AFC East division. The Colts would start horribly, losing their first 10 games, their first 0-10 start since 1986, before an upset home win over eventual NFC Champion Green Bay. That would turn out to be the only good highlight all season for the Colts, as the team fell to a league-worst 3-13 record, and earned the first overall pick in the 1998 NFL Draft, in which they selected quarterback Peyton Manning in what would be the start of a dynasty for the Colts in years to come.
Document 8: 2008 Detroit Lions season: The 2008 Detroit Lions season was the 79th season for the franchise in the National Football League. The Lions entered their third season under head coach Rod Marinelli and were looking to improve on the 7–9 record they put together in 2007. Instead, the Lions had one of the worst seasons in pro sports history. The team lost all sixteen of their games in 2008, becoming the first team since the 1976 Tampa Bay Buccaneers to end an NFL season with no wins and no tied games as well as the first and only team to do it since the schedule was expanded to sixteen games. The Lions were mathematically eliminated from the playoffs by Week 11, when they stood 0–10. The team's victory over the Kansas City Chiefs in Week 16 of 2007 stood as their last until Week 3 of the 2009 season. From the time the Lions recorded a win over the Denver Broncos in 2007 to reach 6–2, the team went 5–47 over their following 52 games (including all of 2008 and 2009) before winning four games in a row at the end of the 2010 season. As of 2017, this is the only team in NFL history to finish a season with a 0–16 record. The 2016 Cleveland Browns and the 2009 St. Louis Rams came close to 0–16, both going 1–15.
Document 9: 1978 Miami Dolphins season: The 1978 Miami Dolphins season saw the team return to the NFL playoffs for the first time since 1974, with an 11–5 record. Quarterback Bob Griese missed the first seven games due to a knee injury. The Dolphins got off to a 5-2 start behind back-up Don Strock. Upon Griese's return the Dolphins earned a birth to the playoffs as a Wild Card. Helping to lead the Dolphins back to the postseason was Running Back Delvin Williams who set a team record with 1,258 yards rushing on the season. In the first playoff game involving two Wild Cards the Dolphins were stunned 17-9 by the Houston Oilers at the Orange Bowl. In the process the Dolphins set two notable records: scoring first in all but one of their sixteen regular season games, and never trailing at any point in eleven games. The former record was equalled by the 2004 Patriots, and the latter was beaten by the 2005 Colts.
Document 10: 1984 Miami Dolphins season: The 1984 Miami Dolphins season was the team's 19th season, and 15th in the National Football League.

They defeated the Miami Dolphins in the Wild Card round of the playoffs, and then in the divisional round they defeated the Tennessee Titans, who had compiled the best record in the AFC over the regular season. However, in the AFC championship game, the Ravens' season came to an end as they were defeated by eventual Super Bowl XLIII champion Pittsburgh Steelers.
Document 12: 2009 Indianapolis Colts season: The 2009 Indianapolis Colts season was the franchise's 57th season in the National Football League and the 26th in Indianapolis.

The 2009 Indianapolis Colts improved upon their 12–4 record from 2008 as well as winning their sixth AFC South division championship in seven years. The Colts also clinched the #1 playoff seed in the AFC. The Colts became the sole undefeated team after week 15. The following week, the Colts lost to the New York Jets after benching their starters. During the playoffs, the Colts defeated the Baltimore Ravens in the divisional round and the New York Jets in the AFC Championship game, but lost to the New Orleans Saints in Super Bowl XLIV, 31–17.
Document 13: 1985 New England Patriots season: The 1985 New England Patriots season was the 16th season for the team in the National Football League and 26th season overall.

They then became the first team in NFL history ever to advance to the Super Bowl by winning 3 playoff games on the road, defeating the New York Jets 26–14, the Los Angeles Raiders, 27–20, and then they went on to stun the football world and did the impossible as they pulled out a massive and stunning upset over the Miami Dolphins 31–14, in the AFC Championship game. The Patriots' win in Miami was their first victory in that stadium since 1969. The win over the Dolphins in the game has gone down as one of the greatest upsets in NFL history, as the Dolphins were heavily favored.
Document 14: 1970 Miami Dolphins season: The 1970 Miami Dolphins season was the team's fifth, and first in the National Football League (NFL). The 1970 season marked the team's first winning season, and their first playoff appearance. The 1970 season was also the first season under head coach Don Shula, as he would be the head coach of the franchise until 1995, a span of 25 years as head coach. The team improved on their 3-10-1 record from 1969, and finished the season 10-4, second in the newly aligned AFC East to only eventual champion Baltimore. The Dolphins would get off to a fresh start, starting 4-1 before losing 3 straight to even their record at 4-4. However, Miami would whip off 6 straight to end the season and clinch their first ever winning season and playoff berth. In their first playoff game, they lost 21-14 in the Divisional Round to the Oakland Raiders, ending Miami's season.
Document 15: 2015 Jacksonville Jaguars season: The 2015 Jacksonville Jaguars season was the franchise's 21st season in the National Football League and the third under head coach Gus Bradley.
