Dome vs Outdoors Performance Splits

Overview

This pillar quantifies how NFL quarterback and kicker performance changes when playing in a climate-controlled dome versus an outdoor stadium. It provides a crucial edge by isolating environmental factors that directly impact scoring and player statistics.

What It Does

The analysis gathers historical game logs for active QBs and kickers, splitting their key statistics into 'Dome' and 'Outdoors' categories. It then calculates the performance differential, such as the change in passer rating or field goal percentage, between the two environments. This creates a player-specific profile highlighting their sensitivity to stadium conditions.

Why It Matters

Weather is a significant, yet often generalized, variable in football trading. By precisely measuring a player's past performance in controlled versus uncontrolled environments, this pillar offers a data-driven edge for player props and game totals that the market may overlook.

How It Works

First, we identify the venue type (dome or outdoors) for every game a player has participated in. Next, we aggregate key performance metrics like completion percentage and field goal accuracy for each venue category. Finally, we calculate the statistical split to generate a 'Dome Advantage' score for each player.

Methodology

The pillar uses career and recent season data (3-year rolling average) for active players with a minimum of 10 games in each environment type. The core calculation is the Performance Split: (Dome Metric - Outdoor Metric) / Outdoor Metric. This produces a percentage differential for metrics like Passer Rating, Yards Per Attempt, and Field Goal Percentage.

Edge & Advantage

This pillar provides a specific, quantifiable edge by moving beyond generic weather analysis to focus on individual player susceptibility to environmental factors, which is critical for pricing player props accurately.

Key Indicators

• QB Passer Rating Split

  high

  The percentage difference in a quarterback's passer rating when playing in a dome versus outdoors. This is a primary indicator of overall passing efficiency.

• Kicker FG% Split

  high

  The absolute difference in a kicker's field goal accuracy between indoor and outdoor games, especially from 40+ yards.

• Completion Percentage Differential

  medium

  Measures the change in a QB's accuracy, indicating how much wind or precipitation affects their ability to connect with receivers.

Data Sources

• Pro-Football-Reference

  Provides comprehensive historical player game logs, including venue and statistical data for every NFL game.
