Reading the defense: How the NFL and AWS quantify coverage responsibility

The NFL and AWS developed an innovative AI framework called Coverage Responsibility to automatically determine defensive player assignments during football plays, addressing a long-standing analytics challenge.

• Used a spatial-temporal transformer architecture inspired by self-driving car technology
• Created three interconnected machine learning models to analyze:
  • Coverage assignments
  • Defender-receiver matchups
  • Target defender identification
• Leveraged AWS services like SageMaker Studio, S3, and Amazon Bedrock for development
• Achieved 88% accuracy in predicting defensive responsibilities
• Enabled new analytics like ranking defenses by coverage disguise techniques

The project represents a significant advancement in football analytics, transforming how defensive strategies can be quantified and understood.
