The 2017 Los Angeles Chargers season is the franchise's 48th season in the National Football League (NFL), the 58th overall and the first under head coach Anthony Lynn.  It will also be the Chargers' first season in Los Angeles since their inaugural 1960 season, when they were in the AFL, as the team exercised its option to move to the city and join the Los Angeles Rams on January 12, 2017.  The 2017 season will be the first of three seasons played at StubHub Center prior to the new stadium being completed. The San Diego Chargers season was the franchise's 42nd season in the National Football League and the 52nd overall.  The team failed to improve on its 9–7 record from 2010, and finished in a three-way tie with the Denver Broncos and Oakland Raiders for the AFC West division title, with an 8–8 record, but lost the tiebreaker to the Broncos and missed the playoffs for a second consecutive season.  For Norv Turner, this was his fifth season as the head coach of the Chargers.  The Chargers had the 18th pick in the 2011 NFL Draft. The Los Angeles Chargers are a professional American football team in the National Football League (NFL) based in the Greater Los Angeles Area.  The club began play in 1960 as a charter member of the American Football League (AFL), and spent its first season in Los Angeles before moving to San Diego in 1961.  They returned to Los Angeles in 2017.  NFL teams assign each of their players a jersey number ranging from 1 through 99.  The Chargers no longer issue four retired numbers.  As of 2010, the team's policy was to have the Chargers Hall of Fame committee evaluate candidates for a player's number to retire after the player has retired from the league after five years.  The committee consisted of Chargers Executive Vice President A. G. Spanos, Chargers public relations director Bill Johnston, San Diego Hall of Champions founder Bob Breitbard, and the presidents of the San Diego Sports Commission and the Chargers Backers Fan Club.  There are few recognized guidelines in sports regarding retiring numbers, and the NFL has no specific league policy.  "You have to have enough numbers for players to wear," said NFL spokesman Greg Aiello.  The Chargers have rarely retired numbers.  The "San Diego Union-Tribune" wrote, "The [Chargers] tend to honor their heritage haphazardly." The San Diego Chargers season was the franchise's 44th season in the National Football League (NFL), the 54th overall, and the 1st under head coach Mike McCoy.  The Chargers finished the regular season with a record of 9–7, improving on their 7–9 record from 2012.  Also, they qualified for the playoffs for the first time since 2009.  The Chargers defeated the Cincinnati Bengals in the Wild Card round by a score of 27–10, but lost to the Denver Broncos in the Divisional round by a score of 24–17.  As of 2016, this is the most recent time the Chargers have qualified for the playoffs.  This would turn out to be the Chargers final playoff appearance in San Diego.
