Return from Soft Tissue Injury
Quantifying performance dips after soft tissue injuries.
Overview
Analyzes the historical performance of NFL players in their first game back from common soft tissue injuries like hamstring or groin strains. It provides a data-driven expectation to counter public overenthusiasm for a returning star player.
What It Does
This pillar aggregates historical game logs for NFL players who missed time with documented soft tissue injuries. It compares their performance in the first game back against their pre-injury baseline and seasonal averages. The analysis accounts for injury severity, player position, and coaching tendencies to generate a realistic performance projection.
Why It Matters
The market often incorrectly prices player props for stars returning from injury, assuming an immediate return to full form. This pillar identifies a consistent pattern of underperformance, providing a significant edge for trading 'under' on receiving, rushing, or fantasy point props.
How It Works
First, the system identifies a player returning from a multi-week soft tissue injury. It then pulls historical data for comparable players, positions, and injury types. The model calculates the average percentage drop in key stats like yards per touch, targets, and snap count, generating a score to adjust standard projections downwards.
Methodology
Calculates a 'Performance Suppression Score' (PSS) based on a 5-year rolling database of NFL player game logs. PSS = (Avg_PreInjury_Baseline - Avg_FirstGameBack_Performance) / Avg_PreInjury_Baseline. The model weighs WR/RB/TE data more heavily and adjusts for Grade 1 vs. Grade 2/3 strains, where Grade 2+ injuries show a stronger suppression effect. The time window is the first game back after missing at least one full game.
Edge & Advantage
This provides a quantifiable edge against narrative-driven markets that overestimate a player's immediate impact, creating clear value on 'under' props.
