Basketball Rotation Index Formula:
From: | To: |
The Basketball Rotation Index is a metric that estimates a player's versatility and overall contribution by combining their points, rebounds, and assists per game into a single value. It serves as a proxy for rotation value in basketball.
The calculator uses the Rotation Index formula:
Where:
Explanation: The geometric mean (cube root of the product) provides a balanced measure that accounts for all three statistical categories equally.
Details: This index helps evaluate players who contribute across multiple statistical categories, identifying versatile players who might be valuable rotation pieces even if they don't excel in any single category.
Tips: Enter the player's average points, rebounds, and assists per game. All values must be zero or positive numbers.
Q1: What is a good Rotation Index value?
A: Values vary by league and position, but generally: 5+ is solid rotation player, 10+ is starter level, 15+ is All-Star caliber.
Q2: Why use geometric mean instead of average?
A: Geometric mean better accounts for balanced contributions across categories and penalizes players who are extremely weak in one area.
Q3: Should other stats be included?
A: For a more comprehensive evaluation, consider adding steals and blocks, but PPG/RPG/APG captures most offensive contributions.
Q4: How does this compare to PER?
A: Rotation Index is simpler but less comprehensive than Player Efficiency Rating (PER), focusing only on three key stats.
Q5: Can this predict playing time?
A: While not perfect, higher Rotation Index values generally correlate with more minutes as coaches value versatile contributors.
