A rule variation that comes into play during the second period of a game when teams must defend the goal that is furthest away from their bench. This rule change is specific to the NHL and some other high-level leagues and is not typically used in lower-level or recreational hockey. The long change rule adds an interesting element to the game, as it requires teams to adapt their strategies and player rotations during the second period. It can impact the flow of the game and lead to unique tactical decisions by coaches and players.
