- Objective: Identify practice-level movement metrics that differentiate Shrine Bowl defenders who reach the NFL
- Data: Shrine Bowl practice tracking data + NFL participation data
- Focus: Linebackers & edge defenders (“box defenders”)
- Key Metric: Directional acceleration scaled by player mass (directional force)
Key Findings:
- Peak speed and peak acceleration do not meaningfully separate NFL vs non-NFL players
- Average directional acceleration and force across reps do
- NFL players show similar peaks, but sustain higher directional force across repetitions
- Directional force also scales with NFL utilization, not just NFL entry
