As Big Sky teams continue their season, the MACD trending indicators will help identify which teams are genuinely improving versus those riding unsustainable momentum. Check back next week for updated analysis.
Metrics Glossary
Four Factors (Dean Oliver’s framework for basketball success):
- eFG% (Effective Field Goal %): Field goal percentage adjusted for 3-pointers being worth more (FGM + 0.5×3PM) / FGA. Higher is better offensively, lower is better defensively.
- TOV% (Turnover Rate): Turnovers per 100 possessions. Lower is better offensively (taking care of the ball), higher is better defensively (forcing turnovers).
- OREB% / DREB% (Offensive/Defensive Rebound Rate): Percentage of available rebounds grabbed. Offensive rebounds create second-chance points; defensive rebounds end opponent possessions.
- FTR (Free Throw Rate): Free throws made per field goal attempt (FTM/FGA). Measures ability to get to the line AND convert. Higher is better offensively, lower is better defensively.
Other Metrics:
- Elo Rating: Chess-style rating system that updates based on game results and opponent strength. Higher Elo indicates stronger team.
- Efficiency Margin: Point differential per 100 possessions (Offensive Efficiency – Defensive Efficiency). Accounts for pace of play.
- MACD (Moving Average Convergence Divergence): Trend indicator comparing 12-game and 26-game exponential moving averages. Positive MACD = improving trend, Negative MACD = declining trend.
