Initializing Team Rosters.
Impact Rating (IR) is a proprietary composite metric developed by NHL Analytica to measure a player's overall contribution beyond raw counting stats. It combines scoring efficiency, shot quality, puck possession impact, and durability into a single score from 0–99.9.
IR is calculated using full-season regular season or playoff data from the NHL Stats API. Minimum games played thresholds apply to filter out small sample sizes.
