Coach Bill Belichick’s system is designed to emphasize specific roles linked to specific abilities. This type of system serves two functions. First, it allows the players and coaches to understand each player’s strengths, weaknesses, and responsibilities. It creates a “group mind” where each team member knows what each other is good at. This naturally builds interdependence by identifying the specific skills each player needs to contribute to the team. Second, it makes it easy to adapt to adversity, setting up a dynamic where players can easily be plugged into roles to replace teammates lost to injury.
