Title: Beyond +/-: A Rating System to Compare NHL Players
Author(s): Dennis F. Lock*+
Companies: St. Lawrence University
Address: 2 Haley Drive, Canton, NY, 13617,
Keywords: NHL ; Hockey ; Rating
Abstract:

While there are many statistics, such as plus/minus, to evaluate a hockey player's performance, few of these statistics effectively compare the worth of different kinds of players. We propose a new, more comprehensive rating method, extending the concept of plus/minus, which aims to take most aspects of a player's game into account. Each player will be rated on the same scale, where the value of each play is determined by how that play increases or decreases the likelihood of victory. This creates a method of rating where one can compare the value of a pure goal scorer to a defensive specialist, and everyone in between.
