2004 Buffalo Bills season

The 2004 Buffalo Bills season was their 45th in the league. The team improved upon their previous season's output of 6–10, finishing 9–7. However, this was the fifth straight season in which the team missed the playoffs.

Buffalo needed a win in the final game of the season against the Pittsburgh Steelers to qualify for the playoffs. However, despite the Steelers playing their third-string, Buffalo lost and subsequently missed the playoffs. It was the only winning season that Buffalo had in the first decade of the 2000s (2000–2009).

According to Football Outsiders, who has tracked every play in the NFL since the early 1990s, the 2004 Bills are statistically the best NFL team (in their record-keeping history) to have failed to qualify for the playoffs.

NFL Draft
The Bills drafted future starters Lee Evans from Wisconsin and J.P. Losman from Tulane in the first round of the 2004 Draft. Buffalo also signed undrafted tight end Jason Peters from Arkansas and converted him into a Pro Bowl offensive tackle. Buffalo traded their 2004 second round pick and 2005 first round pick to move into position to draft Losman.
