The 2005 season was the Kansas City Chiefs' 36th in the National Football League (NFL), their 46th overall, and their fifth and final season under head coach Dick Vermeil.
The 2004 season was the Kansas City Chiefs' 35th in the National Football League (NFL), their 45th overall and their 42nd in Kansas City.
The 2002 season was the Kansas City Chiefs' 33rd in the National Football League (NFL), their 43rd overall and the franchise's 40th in Kansas City, Missouri.

The 1991 Kansas City Chiefs season was the franchise's 22nd season in the National Football League and 32nd overall. They failed to improve on their 11–5 record from 1990 and finished with a 10–6 record. Compared to the Chiefs' 1990 campaign, Steve DeBerg’s consistency had dropped. The running game made up for lost time as Christian Okoye ran for 1,031 yards for the season, Barry Word was productive, and rookie Harvey Williams was outstanding in limited playing time. The Chiefs defeated their division rival, the Los Angeles Raiders in the Wild Card round, resulting in the franchise's first playoff victory since Super Bowl IV in 1970. The next week, the Chiefs lost to the Buffalo Bills in the divisional playoffs.
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 2013 season was the Kansas City Chiefs' 44th in the National Football League (NFL), their 54th overall and their first under the head coach/general manager tandem of Andy Reid and John Dorsey. After their 26–16 win over the Philadelphia Eagles in Week 3, which was also coach Andy Reid's first visit to Philadelphia since the Eagles fired him the season prior, the Chiefs vastly improved on their 2–14 record from 2012 just three weeks into the season. However, despite starting 9–0, the Chiefs would struggle in the second half of the season, losing 5 out of their last 7 games, and losing control of the AFC West. Despite that, they would still make the playoffs. After defeating the New York Giants 31–7 in Week 4, the Chiefs became the first team in NFL history to win two or fewer games in the previous season, and win the first four games the next. On October 13, 2013, against the Oakland Raiders, Chiefs fans broke the Guinness World Record for loudest crowd roar at an outdoor stadium with 137.5 decibels. Seattle Seahawks fans later reclaimed the record on December 2, 2013, with a roar of 137.6 decibels. After the Indianapolis Colts defeated the Denver Broncos in Week 7, the Chiefs were the final undefeated team in the NFL. They were the first team in NFL history to earn the number one draft pick and be the last undefeated team in consecutive years.
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 2015 season was the Kansas City Chiefs' 46th in the National Football League (NFL), their 56th overall and their third under the head coach/general manager tandem of Andy Reid and John Dorsey. The Chiefs went through a poor start in their first six games as they were 1–5, and lost their star running back, Jamaal Charles, to a torn ACL in his right knee during an 18–17 Week 5 loss at home against the Chicago Bears. In week 16, after their ninth consecutive victory and the Baltimore Ravens defeating the Pittsburgh Steelers, the Chiefs clinched a playoff berth, their second in three years. They are the first team since the 1970 Cincinnati Bengals to start the season 1–5 and qualify for the playoffs. They also set the franchise record for the most consecutive victories, winning 10 in a row. In their Wild Card matchup, the Chiefs were set up to play against the Houston Texans. The Chiefs shutout the Texans 30–0 to earn their first playoff win in 22 years, ending what was at the time, until the Bengals broke the record the night the Chiefs won, an NFL record for consecutive playoff losses. The shutout was the Chiefs first ever playoff shutout and remains, as of the 2022–23 playoffs, the most recent playoff shutout in the NFL. The following week, they were defeated by the New England Patriots in the divisional round 27–20.
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 Kansas City Chiefs season was the franchise's 48th season in the National Football League, the 55th as the Kansas City Chiefs, the 58th overall, the fifth under head coach Andy Reid, and first under general manager Brett Veach. They won the AFC West, but lost to Tennessee in the wild-card round after blowing a 21–3 lead at the half. The season was the first to feature future two-time MVP and three-time Super Bowl MVP Patrick Mahomes whose first start came in the last game of the regular season against the Denver Broncos, a game which had no playoff implications as the Chiefs had secured the division in Week 16.
The 2018 Kansas City Chiefs season was the franchise's 49th season in the National Football League, their 59th overall, their sixth under head coach Andy Reid, and their second under general manager Brett Veach. The Chiefs finished 12–4 and won their third consecutive AFC West title, made their fourth consecutive playoff appearance, but lost to the eventual Super Bowl champion New England Patriots in the AFC Championship in overtime. Quarterback Patrick Mahomes won the AP NFL MVP award, becoming the first Chiefs player to ever be named MVP.
The 2018 season was the Jacksonville Jaguars' 24th in the National Football League (NFL) and their second under head coach Doug Marrone. This was their first season in new uniforms, which were revealed in April 2018. The Jaguars had hopes of matching or improving on their 10–6 campaign from the year prior, but despite a 3–1 start, the Jags fell into a 7 game losing streak and failed to improve on their 10–6 record after a Week 10 loss to the Colts. After they lost to the Tennessee Titans in Week 14, the Jaguars fell to 4–9 and were officially eliminated from postseason contention. They finished 5–11, in last place in the AFC South.

That week, the Vikings were eliminated from contention for the NFC North division title, losing 23–10 to the Green Bay Packers. They defeated the New Orleans Saints 26–20 in overtime in the Wild Card round but lost 27–10 to the eventual NFC champion San Francisco 49ers in the Divisional Round.
The 2020 Kansas City Chiefs season was the Kansas City Chiefs' 51st in the National Football League (NFL), their 61st season overall and their eighth under head coach Andy Reid.

They finished with a franchise-record and league-leading 14 wins. The Chiefs appeared in Super Bowl LV, their second consecutive Super Bowl appearance and fourth in franchise history, but lost to the Tampa Bay Buccaneers, 31–9. With the loss, the Chiefs became the sixth defending Super Bowl champion to lose the next year's game, after the 1978 Dallas Cowboys, the 1983 Washington Redskins, the 1997 Green Bay Packers, the 2014 Seattle Seahawks, and the 2017 New England Patriots.
