Published in 2005, the book examines Belichick's formation and rise through the early period of his success with the New England Patriots. Its date matters. This is a portrait written at a particular point in his career, not a retrospective covering everything that happened afterwards.
The word education in the title supplies the organising idea. Halberstam looks beyond the public figure on the sideline towards the people and working environments through which a method develops. That emphasis makes the book more useful than a simple catalogue of victories or a collection of leadership maxims.
