Return to Play (RTP) Performance Dip
Quantifying the performance dip after major injuries.
Overview
This pillar analyzes the historical performance of rugby players in their first two games returning from a long-term injury. It identifies predictable drops in key metrics, providing an edge in player proposition markets.
What It Does
The model identifies players returning from significant time off, typically six weeks or more. It then compares their pre-injury performance baseline across key statistics with the average performance of similarly injured players in their initial return games. This process generates a projected 'performance dip' score for specific metrics like tackle efficiency and error rates.
Why It Matters
Narrative and fan excitement often inflate a star player's expected performance upon their return. This pillar provides a quantitative, data-driven counterpoint, highlighting the statistical reality that most players need time to regain match fitness and sharpness. This gap between public perception and likely outcome creates valuable prediction opportunities.
How It Works
First, the system flags a player returning from an injury classified as long-term. Second, it pulls their 10-game rolling average for key stats before the injury occurred. Third, it cross-references a historical database of player returns to calculate an expected percentage decrease in performance for the first two games back. Finally, it applies this dip factor to the player's baseline to generate a concrete statistical forecast.
Methodology
A 'long-term injury' is defined as any absence exceeding 6 weeks. The pre-injury baseline is a player's 10-game rolling average. The core calculation is the 'Dip Ratio', calculated as (Avg Performance in first 2 games post-injury) / (Avg Performance in 10 games pre-injury) for a cohort of players with similar positions and injury types. This ratio is then applied to the specific player's baseline stats.
Edge & Advantage
This pillar offers an edge by systematically trading against the emotional hype surrounding a player's return, using historical data to pinpoint likely underperformance.
