Context paragraphs:
2015 Detroit Lions season: The Detroit Lions season was the franchise's 86th season in the National Football League, their 82nd as the Detroit Lions and the second under Head Coach Jim Caldwell.  By Week 7 of the season, the Lions had already lost six games, more than they did in the entire 2014 season.  This led to the firing of Offensive Coordinator Joe Lombardi and two other coaches.  After falling to 1–7 the following week, the team fired President Tom Lewand and General Manager Martin Mayhew.  On November 19, the Lions named Rod Wood as team President.  The Lions were eliminated from playoff contention after their loss to St. Louis in week 14.  The team had a 6–2 record in the second half of the season to finish at 7–9, good for third place in the NFC North.  Also this season involved the Lions first win in Green Bay since 1991.

2016 Detroit Lions season: The 2016 Detroit Lions season was the franchise's 87th season in the National Football League, their 83rd as the Detroit Lions and the third under head coach Jim Caldwell.  On January 8, 2016, the Lions hired Bob Quinn as general manager.  This was also the first season in over 40 years in which the Lions had an official cheerleading squad.  The Lions improved upon their 7–9 record from 2015, and clinched a playoff spot for the first time since 2014—the Lions finished tied with the Tampa Bay Buccaneers for the last NFC playoff spot, but won the tiebreaker based on their record against common opponents.  However, the Lions were defeated by the Seattle Seahawks in the Wild Card Round extending their playoff losing streak to nine games.

2007 Miami Dolphins season: The 2007 Miami Dolphins season was the 38th season for the team in the National Football League and 42nd season overall.  The team nearly went winless for the season, but on December 16, the third to last game of the regular season, they beat the Baltimore Ravens, giving them a final record of 1–15.  The Detroit Lions became the first team to go 0–16 the following season.  Their only win of the season gave them the first pick in the 2008 NFL draft.  They also failed to improve upon a 6–10 season in 2006.  Under former head coach Nick Saban in a year that began with high hopes, Saban resigned from the Dolphins to become the head coach at the University of Alabama, after repeatedly saying he would stay with the Dolphins.  The Dolphins entered 2007 in the process of rebuilding under new head coach Cam Cameron, the former offensive coordinator for the San Diego Chargers.  The coaching staff underwent significant changes, with approximately twelve coaches newly hired or reassigned.  Cameron also made various changes to the team's roster, with more than a dozen players being added or re-signed and just as many being released, traded or allowed to sign elsewhere.  Six of the team's losses in 2007 were by margins of three points or less.

The Lions spent most of the season at the bottom of their division, and ended the season with an eight-game losing streak, their worst skid since the winless 2008 season.  It was also the franchise's 21st consecutive season without a playoff win.

It was the Lions' final season playing at Tiger Stadium; the team moved to the Pontiac Silverdome the following season and played home games there until the end of their 2001 season.  Prior to the start of training camp, tragedy would strike the Lions, as Head Coach Don McCafferty died of a fatal heart attack at age 53.  He would later be replaced by Lions assistant Rick Forzano, who would guide the Lions to a 7–7 record in their final season at Tiger Stadium.  This would also be the last season until 2011 when Monday Night Football would air in the city of Detroit as a result of the Lions playing in Pontiac from 1975 to 2001, following by sub par seasons while playing home games at Ford Field during its first eight years.

2002 Detroit Lions season: The 2002 Detroit Lions season was the 73rd season in franchise history.

Following the season, Marty Mornhinweg was fired and Steve Mariucci was hired as the Lions' head coach.  The Lions entered the 2002 season looking to improve on their 2-14 record from 2001 and make the playoffs for the first time since 1999.  They improved on their record, winning 3 games, but continued to disappoint, as the Lions began the season 0-3.  By week 9, the Lions had a 3-5 record after a win over the Dallas Cowboys.  However, after that win, the Lions lost their remaining 8 games to finish the season 3-13 and failed to reach the playoffs.  The Lions also went 0-8 on the road for the second straight season.  As a result, Marty Mornhinweg was fired after the season.  In his 2 seasons as head coach, the Lions went 5-27 for a winning percentage of .156.

With their win over the San Diego Chargers on December 24, the Lions clinched an NFC Wild Card spot in the postseason.  After their loss to the Green Bay Packers in Week 17, it was determined the Lions would play the New Orleans Saints in one of the NFC Wild Card Games, which the Lions lost 45–28.  It was their first playoff berth since 1999.

2014 Detroit Lions season: The Detroit Lions season was the franchise's 85th season in the National Football League, their 81st as the Detroit Lions and the first under a new coaching staff led by head coach Jim Caldwell.
