The Kansas City Chiefs have signed Steve Spagnuolo to a contract extension.

Spagnuolo guided the Chiefs to the second-best scoring defense in the regular season in 2023 as the Chiefs won their eighth straight AFC West championship and second straight Super Bowl.

The Chiefs had on average the youngest defensive team in the NFL at 25.4 years old.

Spagnuolo, 64, was an assistant for Reid for eight seasons with the Philadelphia Eagles before heading out on his own coaching journey that included three years as the head coach of the Rams.
