The 1984 Kansas City Chiefs season was the franchise's 15th season in the National Football League, the 22nd as the Kansas City Chiefs, and the 25th overall.
The 2011 season was the Kansas City Chiefs' 42nd in the National Football League (NFL), their 52nd overall and their third under the head coach/general manager tandem of Todd Haley and Scott Pioli. A 10–6 record in their 2010 season lent high expectations to their 2011 season, but the Chiefs suffered reversed fortunes. A season-ending hand injury to their starting quarterback Matt Cassel in their eighth game of the season proved especially significant. After a 4–4 record with Cassel at the helm, the Chiefs staggered to a 7–9 win–loss record by season end and failed to make the playoffs.
The 2012 Jacksonville Jaguars season was the franchise's 18th season in the National Football League (NFL). It was the first under the new ownership of Shahid Khan and the first and only season for head coach Mike Mularkey. The Jaguars entered the season hoping to improve on their 5–11 record from 2011 and return to the playoffs for the first time since 2007, but did not and were eliminated from postseason contention. This season marked the third time in the last five seasons in which the Jaguars finished fourth in the AFC South. The Jaguars finished with a 2–14 record, not only tying the Kansas City Chiefs for the league's worst record of 2012, but it would also be the worst in franchise history until the team went 1–15 in 2020. Their 1–7 record at home was also their worst home record in team history.
The 2014 season was the Kansas City Chiefs' 45th in the National Football League (NFL), their 55th overall and their second under the head coach/general manager tandem of Andy Reid and John Dorsey. The Chiefs broke the crowd noise record on Monday Night Football against the New England Patriots on September 29, 2014 with a crowd roar of 142.2 decibels. The Chiefs failed to match their 11–5 record from 2013, and missed the playoffs. However, they defeated both teams that would eventually meet in that season's Super Bowl: the New England Patriots and the Seattle Seahawks. The 2014 Kansas City Chiefs became the first NFL team since the 1964 New York Giants, and the only team in the 16 game season era, to complete an entire season with no touchdown passes to a wide receiver.
The 2014 season was the Miami Dolphins' 45th in the National Football League (NFL), their 49th overall and their third under head coach Joe Philbin. Following the appointment of Dennis Hickey, the team had a new general manager for the first time since 2007 after Jeff Ireland was fired on January 7, 2014. The Dolphins equaled their 8–8 record from 2013 and missed the playoffs for a sixth consecutive season.
The 2014 Jacksonville Jaguars season was the franchise's 20th season in the National Football League (NFL) and the second under head coach Gus Bradley. They failed to improve upon their 4–12 record from 2013 and finished 3–13, and finished third in the AFC South for the second straight year. The Jaguars were eliminated from postseason contention after their week 12 loss to the Colts.
The 2015 season was the Jacksonville Jaguars' 21st in the National Football League (NFL) and their third under head coach Gus Bradley. The Jaguars improved on their 3–13 record in 2014, finishing with a 5–11 record and winning their most games in a season since 2011. While they improved upon their previous two seasons, the Jaguars were eliminated from playoff contention before their Week 16 loss to the New Orleans Saints when the Houston Texans defeated the Tennessee Titans earlier in the day.
The 2016 season was the Kansas City Chiefs' 47th in the National Football League (NFL), their 57th overall and their fourth under head coach Andy Reid and the fourth and final season under general manager John Dorsey who was fired June 22, 2017. The Chiefs clinched their first AFC West division title since 2010, beginning a streak of eight consecutive that still stands as of 2023. The Chiefs also clinched a first-round bye for the first time since 2003, but lost to the Pittsburgh Steelers in the Divisional round 18–16.
The 2017 season was the Miami Dolphins' 48th season in the National Football League (NFL), their 52nd overall, their second under general manager Chris Grier and their second under head coach Adam Gase. The team came off from a 10-6 record and a playoff appearance for the first time since 2008. They were seen as potential playoff contenders and looked to make consecutive playoff seasons for the first time since the 2000 and 2001 seasons. However, the team was affected by the loss of starting quarterback Ryan Tannehill, who tore his ACL during practice and was ruled out for the season. The team turned to former Bears quarterback Jay Cutler, who came out of retirement to become Tannehill's replacement and team's starter. After Tannehill got injured, coach Adam Gase called former Denver Broncos quarterback Peyton Manning about possibly coming out of retirement and taking Tannehill's place. However Manning later declined the idea of coming out of retirement. Gase was the QB coach and offensive coordinator of Peyton's Broncos between the 2012 and 2014 seasons. Additionally, the Dolphins were also one of the teams Peyton considered signing with following his release by the Colts in 2012. Later during the season, the team traded starting running back Jay Ajayi to the eventual champion Philadelphia Eagles in exchange for a 2018 fourth round draft pick on October 31.
The 2017 season was the Jacksonville Jaguars' 23rd in the National Football League (NFL) and their first under head coach Doug Marrone. Marrone was hired after acting as the team's interim head coach for the final two games of the 2016 season. The team improved on their 3–13 record from 2016 and ended their 10-year playoff drought dating back to 2008 with a Week 15 win over the Houston Texans. They also secured their first winning season since 2007 after a 30–24 win over the Seattle Seahawks. On December 24, 2017, they clinched their third division title, and their first AFC South title following a Tennessee Titans loss. They won the wild card game against the Buffalo Bills 10–3, then headed to Pittsburgh, beating the Pittsburgh Steelers 45–42 to advance to the AFC Championship to face the New England Patriots, the first time that they had made the AFC Championship game since 1999. Despite leading for much of the game, the Jaguars would allow two fourth quarter touchdowns, and ultimately lost to the Patriots 24–20.
The 2018 season was the Miami Dolphins' 49th in the National Football League (NFL), their 53rd overall and their third and last under head coach Adam Gase. During the offseason, the Dolphins tweaked their uniforms' orange color to better align with their classical past and history. For the second straight season, they also brought back their throwback uniforms from the Shula/Marino eras and wore them for three games.
The 2018 season was the New York Jets' 49th in the National Football League (NFL), their 59th overall and their fourth and final under head coach Todd Bowles. Despite starting 3–3, they lost 9 of their last 10 games. In Week 3, the Jets lost to the Browns by a score of 21–17, becoming the first team to lose to the Browns since the Chargers lost 20–17 on Christmas Eve 2016. The win by the Browns ended a 19-game winless streak. Week 6 marked the first season the Jets have scored 40+ points in multiple games since the 2008 season. They were officially mathematically eliminated from playoff contention for the 8th consecutive season after the Titans defeated the Jaguars 30–9 in Week 14. The Jets failed to improve on their 5–11 record from the previous season with a 38–3 blowout loss in Week 17 to the New England Patriots, finishing at last place in the AFC East with a 4–12 record. Following the season finale, the Jets fired Bowles.
The 2020 season was the New York Jets' 51st in the National Football League (NFL), their 61st overall, their second under general manager Joe Douglas and their second and final under head coach Adam Gase. They failed to improve upon their 7–9 record from 2019 or return to the playoffs for the first time since 2010. Their 2–14 record was their worst record since their 1996 campaign in which they went 1–15, and shortly after the Jets closed their season with a loss to the New England Patriots the team fired Gase as head coach.
The 2020 season was the Indianapolis Colts' 68th in the National Football League (NFL) and their 37th in Indianapolis. It was also their third season under head coach Frank Reich and fourth under the leadership of general manager Chris Ballard. Long-time San Diego/Los Angeles Chargers quarterback Philip Rivers signed a one-year contract worth $25 million on March 17, 2020, to take over as the team's starting quarterback, reuniting him with Frank Reich, who served as quarterbacks coach for the Chargers during the 2013 season.
The 2020 season was the Los Angeles Chargers' 51st in the National Football League (NFL), their 61st overall, their fifth in the Greater Los Angeles Area, and their fourth and final season under head coach Anthony Lynn.

This is also the Chargers' first season since 2007 with new uniforms, which were unveiled on April 21, 2020. The uniforms are somewhat similar in design to the ones they donned in their inaugural season in 1960.
The 2021 season was the Cincinnati Bengals' 52nd season in the National Football League (NFL), their 54th overall and their third under head coach Zac Taylor. They also played in new uniforms for the first time since 2004. The Bengals finished with a 10–7 record, exceeding their win total from the previous two seasons combined. The Bengals clinched their first winning season, first playoff appearance, and first AFC North title since 2015. It also marked their first Super Bowl appearance since 1988.
