🎮 Demo Mode

The app works out-of-the-box with mock data:

• No API key required
• 200+ players with realistic projections
• All features fully functional
• Perfect for testing and learning

🔑 Using Real Data (Optional)

For real NFL data, get a free SportsDataIO API key:

1. Sign up at sportsdata.io (free tier: 1000 requests/month)
2. Get your API key
3. Open app.py and replace:

   API_KEY = "YOUR_SPORTSDATAIO_KEY_HERE"

   with your actual key
4. Restart the app

With real data you get:

• Actual NFL projections
• 3-year historical statistics
• Real player ages and injury status
• Team performance metrics
• Strength of schedule analysis

📊 How It Works

Enhanced Valuation Formula

Each player receives an adjusted value based on:

Adjusted Value = (
  Base Projection × 60% +
  Historical Average × 20% +
  Team Performance × 10% +
  Matchup SOS × 5%
) × Age Factor × Injury Factor

Age Adjustments

• Under 25: 1.0x (baseline)
• 25-27: 1.05x (prime years boost)
• 28-29: 1.0x (still productive)
• 30-31: 0.9x (slight decline risk)
• 32+: 0.8x (significant age risk)

VORP Baselines

• QB: Top 12 (1-QB leagues)
• RB: Top 24
• WR: Top 30
• TE: Top 12
• DL/LB/DB: Top 24-30 (IDP)

💻 Technology Stack

• Streamlit - Interactive web framework
• Pandas - Data analysis
• Altair - Declarative visualizations
• FuzzyWuzzy - Fuzzy string matching
• Requests - HTTP library

🔧 Customization

Custom Scoring Settings

Edit app.py to match your league:

# Adjust valuation weights
SCORING_WEIGHTS = {
    'projections': 0.50,       # Reduce projection weight
    'historical': 0.30,        # Increase historical weight
    'team_performance': 0.10,
    'matchup_sos': 0.05,
    'age_injury': 0.05
}

# Adjust position baselines for league size
POSITION_BASELINES = {
    'QB': 10,  # 10-team league
    'RB': 20,  # Fewer starting RBs
    # ...
}

Add Machine Learning

Enhance predictions with scikit-learn:

from sklearn.ensemble import RandomForestRegressor

# Train on historical data
model = RandomForestRegressor()
model.fit(historical_features, actual_points)

# Make predictions
enhanced_projection = model.predict(current_features)

See config_example.py for more customization options.
