Key Takeaway from Literature

The consensus from defensive analytics research:

  1. Measurement is hard: Defense is inherently more difficult to quantify than offense
  2. Process beats outcomes: Shot quality metrics more reliable than opponent shooting
  3. Context matters: Scheme, teammates, and role affect individual metrics
  4. Multi-year needed: Single seasons have too much variance
  5. Video essential: Numbers identify questions; film provides answers
  6. Humility required: Best metrics explain only 30-40% of defensive variance
