Advanced statistics in hockey are becoming widely popular and have become more refined over the past few years. Instead of tracking goals (as plus-minus does), possession metrics take note of shot attempts for and against, and in doing so, can show patterns and trends when certain players are on the ice.

By tracking what teams do when they have the puck, we can determine things like puck possession, scoring chances, how teams spend their zone time, and more.

For team-based analysis, the common terms in the lexicon are Corsi and Fenwick (we'll talk more about these in a moment). For players, you'll primarily refer to Corsi, deployment metrics and PDO (also something we'll cover down below).

Regularly-used and kept statistics, such as time on ice (TOI), save percentage and shooting percentage, are also applied in advanced stats but used in different ways. PDO, for example, combines shooting percentage and save percentage to show scoring trends for teams and players - i.e. are hot goal-scoring stretches just streaks, or is this indicative of a long-term pattern?
