Man-to-man defense is a type of defensive tactic used in
team sports such as
American football,
association football,
basketball, and
netball, in which each player is assigned to defend and follow the movements of a single player on offense. Often, a player guards his counterpart (e.g.
center guarding center), but a player may be assigned to guard a different position. However, the strategy is not rigid, and a player might switch assignment if needed, or leave his own assignment for a moment to
double team an offensive player. The term is commonly used even in women's basketball, though the gender-neutral 'player-to-player' also has some usage.
