Football.
The penultimate team sport. Each and every position on the football field is operationally dependent on another. Much like the human body, each part is one piece of a holistic entity that, when properly attuned, can ebbs and flows seamlessly as if meant to be one.
The Football team, just like the human body, is also more dependent upon certain pieces than others. Without the feet, mobility and the power of the legs are drastically limited. Without the core, all appendages must take on more responsibility than they can handle. More than any other, without the mind, the body is but a driverless vessel.
