It would be the first season the franchise would have involving quarterback Philip Rivers. The team improved on their 4–12 record in 2003 and finished the regular season 12–4, made the playoffs for the first time in nine years, and captured their first division title since the 1994 season. In the playoffs they lost in overtime to the New York Jets. At the end of the season Marty Schottenheimer was named NFL Coach of the Year.

Offseason

NFL draft

Entering the draft, the consensus top pick was Ole Miss quarterback Eli Manning. However, Manning had said prior to the draft that he did not want to play for the Chargers and would not sign with them if he was drafted. The Chargers would strike a deal with the Giants before the draft that would shape the future of both franchises. The Chargers would select Manning first overall, as they had intended to. The Giants would then draft quarterback Philip Rivers of North Carolina State, and then swap him and two 2005 draft picks for Manning.
