1981 San Diego Chargers season

The 1981 San Diego Chargers season began with the team trying to improve on their 11–5 record in 1980. In the playoffs they beat the Dolphins in a game known as the Epic in Miami and lost to the Bengals in a game known as the Freezer Bowl.

During this season, the Chargers lost two key players by way of trade. Before Week 3, wide receiver John Jefferson was dealt to the Green Bay Packers, while defensive end Fred Dean would be dealt to the eventual Super Bowl champion San Francisco 49ers by Week 5. The season was chronicled on September 18, 2008 for America's Game: The Missing Rings, as one of the five greatest NFL teams to never win the Super Bowl.
