MVP Dependency Factor

Overview

This pillar analyzes how much a team's win probability drops when its most valuable player has a poor shooting night. It quantifies a team's resilience, revealing hidden vulnerabilities for specific matchups.

What It Does

The MVP Dependency Factor calculates a score by comparing a team's overall win percentage to its win percentage in games where its star player shoots below a specific threshold. It isolates the star's impact on winning, controlling for other variables. A high score indicates a fragile team structure heavily dependent on one player's performance.

Why It Matters

This provides a data-driven measure of a team's structural integrity, which is often overlooked by surface-level analysis. It gives a predictive edge in games where a star faces a tough defensive matchup or is known for inconsistent performances, helping to identify potential upsets.

How It Works

First, the system identifies a team's primary star based on usage rate and PER. It then scans historical game logs to find all instances where that player had a 'poor shooting night'. The team's win percentage in those specific games is calculated and then compared against their overall season win percentage to derive the final dependency score.

Methodology

The Dependency Factor (DF) is calculated as: DF = (Overall Win % - Poor Night Win %). A 'Poor Night' is defined for a star player as any game with a Field Goal Percentage (FG%) below 40% on a minimum of 15 Field Goal Attempts (FGA). The analysis uses a rolling 82-game window to stay current.

Edge & Advantage

This pillar identifies overvalued teams that lean too heavily on one player. It provides a contrarian signal against markets that may not fully price in the risk of a star having an off night.

Key Indicators

• Dependency Score

  high

  The absolute percentage point drop in a team's win rate when their star has a poor shooting night.

• Star Usage Rate

  medium

  The percentage of a team's offensive plays that are used by the star player while on the court.

• Supporting Cast EFG%

  low

  The effective field goal percentage of all other players on the team, indicating their ability to pick up the slack.
