Gates consistently provided key catches, especially on third downs, and served as a safety value for Chargers quarterbacks when plays went off script.

The four-person class is the first since 2005 with fewer than six inductees. Adam Vinatieri also missed out in his first chance.

Gates, who caught 116 touchdown passes in a 16-year career spent entirely with the Chargers, is elected alongside defensive end Jared Allen, wide receiver Sterling Sharpe and cornerback Eric Allen.
