Lineup VORP Loss Calculation

Overview

This pillar calculates the total Value Over Replacement Player (VORP) lost from a team's current injury list. It provides a precise, data-driven measure of how much a team is weakened, moving beyond simple player status reports.

What It Does

The analysis aggregates the VORP for every player on a team's official injury report for an upcoming game. This cumulative score represents the total on-court value the team is missing. The pillar then translates this raw VORP loss into a projected point spread adjustment, offering an actionable metric for bettors.

Why It Matters

Standard injury reports are binary; a player is either in or out. This pillar provides a nuanced, quantitative measure of how much an absence truly matters, allowing for more precise adjustments to game predictions and trading lines.

How It Works

First, the system pulls the latest official injury report for a specific team. Next, it retrieves the current VORP rating for each injured player from advanced statistical databases. It then sums these VORP values to generate a total 'VORP Loss' score, which is finally converted into an estimated point spread impact.

Methodology

The pillar calculates Total VORP Loss (TVL) using the formula: TVL = Σ(VORP_player) for all players on the official injury report. VORP data is sourced from per-100 possession statistics, updated daily. The point spread adjustment is estimated using a regression model: Adjusted Spread ≈ 0.85 * TVL, a coefficient derived from backtesting historical NBA game outcomes and injury data.

Edge & Advantage

It provides a single, objective number for injury impact, moving beyond subjective analysis and capturing the cumulative loss of key role players, not just superstars.
