Optimizing NFL Draft Selections with Machine Learning Classification
This research explores using machine learning, specifically Random Forest models, to optimize NFL draft selections. It compares Best-Player-Available (BPA) and need-based drafting strategies, finding that a need-based approach, when combined with AI, yields more accurate and realistic draft predictions. The model integrates quantitative player metrics and qualitative scouting reports, demonstrating AI's potential to reduce human error and improve decision-making in sports management.
Executive Impact & Key Findings
The integration of AI in NFL draft optimization offers tangible benefits, improving prediction accuracy and strategic decision-making for franchises.

Random Forest Regressor Performance
0.942 Pearson's Correlation Coefficient (PCC)The Random Forest regressor achieved a high Pearson's Correlation Coefficient (PCC) of 0.942, indicating a strong linear relationship between predicted and actual draft pick values. This demonstrates the model's robustness in capturing complex player attribute relationships. (Table 3, p. 9)
Optimal Train:Test Split Ratio
4:1 Train:Test Split RatioAn 80:20 (4:1) train:test split ratio consistently yielded the most efficient results, balancing predictive accuracy and avoiding overfitting. Higher ratios showed diminishing returns and increased runtime. (Table 3, Figure 2, p. 9-10)
| Model | RMSPE | PCC |
|---|---|---|
| Random Forest (n=200) | 0.41031 | 0.94196 |
| Decision Tree Regressor | 0.53062 | 0.89107 |
| SVM (linear) | 0.49095 | 0.89657 |
Random Forest consistently outperformed Decision Tree Regressor (DTR) and Support Vector Machine (SVM) in predicting draft pick values across different training data spans, yielding superior RMSPE and PCC values. (Tables 5 & 6, p. 11)
Physical Attributes & NLP Analysis
Initial feature engineering attempts to include physical attributes like height and weight did not significantly improve model performance. This is attributed to the role-specific nature of physical requirements in the NFL. Similarly, converting expert text comments into numerical grades using tf-idf proved less effective, potentially due to the bimodal distribution of sentiment scores. (Tables 7-10, p. 11-12)
Key Takeaway: Player attributes must be context-aware and position-specific for effective predictive modeling in the NFL.
AI-Driven NFL Draft Simulation Pipeline
The AI-driven NFL draft simulation model follows a multi-step approach, from data preparation and predictive modeling with Random Forest to the application of specific draft strategies (BPA or need-based) and final evaluation of simulated outcomes. (Figure 1, p. 8)
| Strategy | MAE | Top-3 Accuracy |
|---|---|---|
| Best-Player-Available (BPA) | 8.8 | 71.9% |
| Need-Based Drafting | 6.7 | 77.5% |
Comparing the 2017 NFL draft simulation, the need-based drafting strategy significantly outperformed the Best-Player-Available (BPA) strategy, demonstrating a lower Mean Absolute Error (MAE) and higher Top-3 accuracy. This suggests that incorporating team needs makes AI-driven draft predictions more realistic. (Section 3.5, p. 15)
MAE of Need-Based Drafting
6.7 Mean Absolute Error (MAE)The need-based drafting simulator achieved a Mean Absolute Error (MAE) of 6.7, meaning on average, each selection differed from the actual by 6.7 picks. This was the lowest MAE observed, indicating improved prediction realism. (Section 3.4, Figure 4, p. 14)
Top-K Accuracy for Need-Based Drafting
77.4% Top-K Accuracy (within 3 picks)The need-based drafting strategy achieved a Top-K accuracy score of 77.4%, meaning 77.4% of predictions were within 3 picks of the true selection. This highlights the model's ability to identify prospects with high likelihood of success. (Section 3.4, p. 14)
