The Jaguars, who were in their second year of "rebuilding" under general manager Gene Smith, improved upon their 7–9 record from 2009, but narrowly missed the playoffs with an 8–8 record. Although blackouts were a problem in 2009 for the franchise, they sold out all of their 2010 home games.

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 2013 Buffalo Bills season was the franchise's 44th season in the National Football League (NFL) and the first under head coach Doug Marrone. It was also the final season under the ownership of Ralph Wilson, who died in March 2014 at the age of 95.

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 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 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.

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.

The 2020 season was the Jacksonville Jaguars' 26th season in the National Football League (NFL), their eighth and final season under general manager David Caldwell and their fourth and final season under head coach Doug Marrone.
