Defensive Point Shares Calculator

The formula is complex and involves several steps: 1) Calculate team defense value, 2) Determine player's share of team minutes, 3) Apply a scaling factor. The final DPS is a fraction of the team's defensive value attributed to the player based on their ice time.

Defensive Point Shares attempts to quantify a player's defensive contribution to their team's success. It's based on the premise that good defensive play prevents goals, which in turn contributes to winning. The stat considers how many goals a team prevents compared to league average, and then attributes a portion of that value to each player based on their ice time. It's particularly useful for comparing defensive contributions across different teams and seasons.

This stat is valuable for assessing a player's defensive impact, especially for defensemen and defensive forwards. It provides a way to quantify defensive contributions, which are often harder to measure than offensive ones.

Defensive Point Shares is part of the Point Shares system developed by Justin Kubatko, gaining prominence in advanced hockey analytics in the 21st century.

DPS is part of the broader Point Shares system, which aims to divide credit for a team's success among its players. It represents an attempt to create a single number that captures a player's overall defensive value.

DPS is an estimate based on team performance and ice time, not individual defensive actions. It doesn't account for quality of competition, specific defensive skills, or situational usage.

If a player has 1500 minutes on a team that allowed 200 goals over 4920 total team minutes, in a league averaging 3.0 goals per game, their DPS might be around 1.5 (exact value depends on the specific calculation method).

Defensemen like Nicklas Lidstrom and Zdeno Chara have historically accumulated high Defensive Point Shares due to their excellent defensive play and high ice time.
