The 2006 Jacksonville Jaguars season was the franchise's 12th season in the National Football League (NFL) and the 4th under head coach Jack Del Rio. The Jaguars failed to improve on their 12–4 record from 2005. The Jaguars finished in third place in the AFC South and finished the season at 8–8. Although the Jaguars were 8–5 after thirteen games, they lost their next three games in a row and missed the postseason for the second time in three seasons.
The 2001 season was the Kansas City Chiefs' 32nd in the National Football League (NFL) and their 42nd overall. It was their first year under head coach Dick Vermeil and 13th under general manager Carl Peterson. They finished the regular season with a 6–10 record.
The 2008 Jacksonville Jaguars season was the franchise's 14th season in the National Football League (NFL) and the 6th under head coach Jack Del Rio. The Jaguars failed to improve upon their 11–5 record from 2007 and did not make the playoffs. The Jaguars struggled to a 5–11 finish, the franchise's worst record since 2003. The team's struggles were in part the result of a rash of injuries to the team's offensive line. The Jaguars lost starting guards Vince Manuwai and Maurice Williams for the season within the first quarter of the opening game. Tackle Richard Collier's career ended in early September when he was brutally attacked and shot 14 times. Center Brad Meester missed the first two months of the season and guard Chris Naeole, signed to the roster mid-season in response to these injuries, was injured in pregame warmups before playing a single snap. Against teams with smaller defensive linemen, the 2008 Jaguars offense resembled the 2007 offense because the line was able to dominate. An example is the 23–21 victory in Indianapolis against the Colts that saw David Garrard drive the Jaguars into field goal range in the final minute, culminating with Josh Scobee booting the game-winning 51-yard field goal. However, the Jaguars overall struggled, especially in the second half of the season, as evidenced by a 21–19 loss to the Bengals, who entered the game with an 0–8 record.
The 1995 Jacksonville Jaguars season was the franchise's 1st season in the National Football League and the 1st under head coach Tom Coughlin.

The 1999 season was the Jacksonville Jaguars' 5th in the National Football League and their fifth under head coach Tom Coughlin. Wide receiver Jimmy Smith set a franchise record for most receptions and receiving yards in one season. Smith would finish second in the NFL in receiving yards with 1,636 yards. The Jaguars’ regular season record of 14–2 still stands as their best record in franchise history. This would be the last time Jacksonville made the playoffs until 2005, the last season the team won a playoff game until 2007 and the last time the Jaguars won any division title until they won the AFC South title in 2017.
The 1997 Jacksonville Jaguars season was the franchise's 3rd season in the National Football League and the 3rd under head coach Tom Coughlin. The team looked to reach the AFC Championship for the second straight year following a surprising run in 1996. The Jaguars improved upon their previous 9-7 record and won 11 games.

The 1998 Jacksonville Jaguars season was the franchise’s fourth year in the National Football League (NFL).

An 0–8 record in road games eliminated any chance of postseason play.
The 2004 Jacksonville Jaguars season was the tenth season in franchise history, Jack Del Rio’s second year as the head coach of the Jacksonville Jaguars and Byron Leftwich’s first full year as starting quarterback. In a time of transition for the franchise, Del Rio’s coaching and Leftwich’s play helped to pull the Jaguars out of a four season slump to a finish of 9–7, placing second in the AFC South. However, they missed the playoffs for the fifth successive season.
The 2005 Jacksonville Jaguars season was the eleventh season in franchise history.

Del Rio finished his tenure in Jacksonville with a 69-73 record in the regular season and 1-2 in the playoffs. He was also just 4 wins shy of surpassing his predecessor, Tom Coughlin as the winningest head coach in Jaguars history. The Jaguars had hoped to improve on their 8–8 record from 2010, but exceeded their loss total in Week 13, and were officially eliminated from postseason contention.
