π Definition of Substitution Strategies
In sports, a substitution strategy involves replacing one player on the field with another during a game. This isn't just about resting players; it's a tactical decision designed to impact the game's outcome by changing the team's dynamics, addressing weaknesses, or exploiting opponent vulnerabilities.
π History and Background
The concept of substitution has evolved significantly across different sports. Initially, substitutions were limited and primarily used for injuries. Over time, rule changes allowed for more strategic substitutions, leading to the development of complex tactical approaches. For example, in soccer, the limited number of substitutions forces coaches to carefully consider when and who to bring on, making it a critical aspect of game management.
