Strong Link vs Weak Link Sports
Team building is a game of resource allocation in many modern sports. Managers are allocated a certain amount of money to spend on players, or a certain number of player contracts to trade against the team's salary cap. As a result, team formation eventually becomes a tradeoff exercise.
