2004 Kansas City Chiefs season

The 2004 season was the Kansas City Chiefs' 35th in the National Football League, their 45th overall and their 42nd in Kansas City.
The 2004 season proved not to be as successful as the team's previous season. Though the Chiefs finished the regular season with the most yards and the second highest number of points, they also had a losing record of 7–9 and no playoff appearance. In fact, the Chiefs' 483 points-scored was the highest total in NFL history for a team that finished the season with a losing record. The Chiefs joined the 1975 Buffalo Bills as the only teams in NFL history to score an average of at least 30 points per game and miss the playoffs.

Offseason

The Chiefs made NFL history in this game, as they set a record by having 8 rushing touchdowns, the most in a single game in the Super Bowl Era.

The loss ended the Chiefs' seven-game home unbeaten streak against the Patriots, losing to them at home for the first time since the 1964 season.
