    • Only event logs such as passes and shots
    • GPS or local-positioning data, inertial sensors and heart-rate data
    • Only the final score of a match
  4. What does the NBA’s Defensive Pressure Score use optical tracking data to estimate?
    • The probability a soccer shot becomes a goal
    • The athlete’s blood oxygen level during training
