Buffalo Bills

A couch player: The Bills won consecutive AFL Championships in 1964 and 1965, the only major professional sports championships from a team representing Buffalo. After joining the NFL, they became perennial postseason contenders during the late 1980s and 1990s. Their greatest success occurred between 1990 and 1993 when they appeared in a record four consecutive Super Bowls; an accomplishment often overshadowed by them losing each game. From 2000 to 2016, the Bills endured the longest active playoff drought of the four major North American professional sports, making them the last NFL franchise and the last in the four leagues to qualify for the postseason in the 21st century.

Baltimore Ravens

A couch player: he Ravens have been one of the more successful franchises since their inception; the team has qualified for the NFL playoffs 13 times since 2000 with two Super Bowl championship titles (Super Bowl XXXV and Super Bowl XLVII), two AFC Championship titles (2000 and 2012), four AFC Championship game appearances (2000, 2008, 2011 and 2012), six AFC North division titles (2003, 2006, 2011, 2012, 2018, and 2019) and 16 playoff victories.

New York Jets

A couch player: The Jets advanced to the playoffs for the first time in 1968 and went on to compete in Super Bowl III where they defeated the Baltimore Colts, becoming the first AFL team to defeat an NFL club in an AFL–NFL World Championship Game. Since 1968, the Jets have appeared in the playoffs 13 times, and in the AFC Championship Game four times, most recently losing to the Pittsburgh Steelers in 2010. However, the Jets have never returned to the Super Bowl, making them one of two NFL teams to win their lone Super Bowl appearance, along with the New Orleans Saints. Apart from the Cleveland Browns and the Detroit Lions, who have never reached the Super Bowl (although both won NFL championships prior to 1966), the Jets' drought is the longest among current NFL franchises.

Miami Dolphins

A couch player: n 2008, the Dolphins became the first team in NFL history to win their division and make a playoff appearance following a league-worst 1–15 season. That same season, the Dolphins upset the New England Patriots on the road during Week 3 thanks to the use of the gimmick Wildcat offense, which handed the Patriots their first regular-season loss since December 10, 2006, in which coincidentally, they were also beaten by the Dolphins. To date, 2008 is also the last season the Dolphins won the AFC East.

Kansas City Chiefs

A couch player: The Chiefs won three AFL championships, in 1962, 1966, and 1969, and were the second AFL team (after the New York Jets) to defeat an NFL team in an AFL–NFL World Championship Game, when they routed the Minnesota Vikings in Super Bowl IV. That victory on January 11, 1970, was the final such competition before the leagues' merger went into full effect. The Chiefs were also the second team, after the Green Bay Packers, to appear in more than one Super Bowl (and the first AFL team to do so) and the first to appear in the championship game in two different decades.

New England Patriots

A couch player: The Patriots hold the records for most Super Bowl wins (6, tied with the Pittsburgh Steelers), appearances (11), and losses (5, tied with the Denver Broncos). Generally unsuccessful prior to the 21st century, the team enjoyed a period of dominance under head coach Bill Belichick and quarterback Tom Brady from 2001 to 2019. The Brady–Belichick era, regarded as one of sports' greatest dynasties, would see the Patriots claim nearly every major Super Bowl record.

Cincinnati Bengals

A couch player: The Cincinnati Bengals are a professional American football franchise based in Cincinnati. The Bengals compete in the National Football League as a member club of the league's American Football Conference North division. The club's home stadium is Paul Brown Stadium, located in downtown Cincinnati

Jacksonville Jaguars

A couch player: The Jaguars made an early impact in the NFL by clinching four consecutive playoff berths, two division titles, and two AFC Championship Game appearances from their second and fifth seasons of play. They are the youngest NFL expansion team to appear in a conference championship (by their second season in 1996, along with the Panthers) and clinch their conference's top seed (by their fifth season in 1999). The Jaguars have been less successful after their early seasons, with only three playoff appearances and one division title since 2000. Jacksonville is one of four NFL franchises to have never played in the Super Bowl.

Denver Broncos

A couch player: The Broncos were barely competitive during their 10-year run in the AFL and their first seven years in the NFL. They did not have a winning season until 1973. In 1977, four years later, they qualified for the playoffs for the first time in franchise history and advanced to Super Bowl XII. Since 1975, the Broncos have become one of the NFL's most successful teams, having suffered only eleven losing seasons. They have won eight AFC Championships (1977, 1986, 1987, 1989, 1997, 1998, 2013, 2015), and three Super Bowl championships (1997 (XXXII), 1998 (XXXIII), 2015 (50)), and share the NFL record for most Super Bowl losses (5 — tied with the New England Patriots).

Pittsburgh Steelers

A couch player: The Steelers enjoy a large, widespread fanbase nicknamed Steeler Nation. They currently play their home games at Heinz Field on Pittsburgh's North Side in the North Shore neighborhood, which also hosts the University of Pittsburgh Panthers. Built in 2001, the stadium replaced Three Rivers Stadium, which had hosted the Steelers for 31 seasons. Prior to Three Rivers, the Steelers had played their games in Pitt Stadium and at Forbes Field.

Los Angeles Chargers

A couch player: The Los Angeles Chargers are a professional American football team based in the Los Angeles metropolitan area. The Chargers compete in the National Football League (NFL) as a member club of the league's American Football Conference (AFC) West division. The Chargers play their home games at SoFi Stadium in Inglewood, California, which the club shares with the Los Angeles Rams.

Houston Texans

A couch player: While the team mainly struggled in their first decade of play, they found success in the 2011 season, winning their first division championship and clinching their first playoff berth. The Texans have gone on to win five more AFC South championships in 2012, 2015, 2016, 2018 and 2019. As of the 2020 season, they are the only franchise to have never appeared in a conference championship game.

Indianapolis Colts

A couch player: The Colts played in two Super Bowl games while they were based in Baltimore, losing to the New York Jets in Super Bowl III and defeating the Dallas Cowboys in Super Bowl V. The Colts relocated to Indianapolis in 1984 and have since appeared in the playoffs 16 times, won two conference championships, and won one Super Bowl, in which they defeated the Chicago Bears in Super Bowl XLI.
