Line

In ice hockey, a line is a group of forwards that play in a group, or “shift”, during a game.

A complete forward line consists of a left wing, a center, and a right wing, while a pair of defensemen who play together are called “partners”. Typically, an NHL team dresses twelve forwards along four lines and three pairs of defensemen, though some teams elect to dress a seventh defenseman, or a thirteenth forward.

In ice hockey, players are substituted “on the fly”, meaning a substitution can occur even in the middle of play as long as proper protocol is followed (under typical ice hockey rules, the substituting player cannot enter the ice until the substituted player is within a short distance of the bench and not actively playing the puck); substitutions can still be made during stoppages. Usually, coordinated groups of players (called linemates) are substituted simultaneously in what are called line changes. Linemates may change throughout the game at the coach’s discretion.
