4 Conclusions and Recommendations

1. Injury Prevention: Focus on positions with high injury rates (Cornerbacks and Wide Receivers).
2. Team Strategy: Investigate why losing teams have slightly higher injury rates and durations.
3. Seasonal Planning: Implement strategies to reduce injuries in high-risk weeks (Week 1 and Week 12).
4. Player Management: While age doesn’t strongly correlate with injury risk, individual player history should be considered.
5. Geographic Considerations: Teams in states with higher injury rates (e.g., Ohio) might need to review their training and medical protocols.
