Chiefs' Defense Emerges as Key Factor in Super Bowl Run

Under Coordinator Steve Spagnuolo, Kansas City's Defense Has Transformed Into One of the NFL's Top Units

Kansas City Chiefs' defense, under coordinator Steve Spagnuolo, has emerged as a key factor in the team's success, holding the Baltimore Ravens to a -0.20 EPA per play and a 28% first down rate in the AFC Championship game.
Spagnuolo's defensive strategies have been praised for their adaptability and effectiveness, with the Chiefs' secondary providing particularly strong coverage.
The Chiefs' defense has been instrumental in frustrating opponents, including MVP candidate Lamar Jackson, who was forced to hold onto the ball for an average of 3.3 seconds due to the Chiefs' coverage.
Spagnuolo, who has already won Super Bowls with multiple franchises, could become the first four-time Super Bowl-winning coordinator with a victory in the upcoming game against the 49ers.
The Chiefs' defense has undergone a significant transformation since Spagnuolo's arrival in 2019, ranking No. 2 in scoring and No. 2 in total yards this season.
