No player lives under a microscope on a football field more than a quarterback. A team's success is significantly tied to their impact and individual performance, and their team's success is often magnified through their own individual scrutiny. The position is the brain trust of the offense, the one with the most touches over the course of an individual game, and, in football's modern era, the most versatile player on the field.
Molding a football team requires deep coordination with the position. A team can play a certain style only if its quarterback can handle the workload, and the player often dictates which plays are called for a particular style.
