The Air Force Academy gave Parcells his first head coaching job, but Parcells dispised recruiting and also realized that his mindset was better suited for the professional level. Two disappointing seasons into his Air force tenure, Parcells jumped at the chance to move into the professional coaching ranks as the linebackers coach for the New York Giants
His first stint barely lasted past the first mini camp, as his family convinced Parcells to move back to Colorado. It was at this time in his life that Parcells questioned his desire to coach football. He sold real estate for awhile before realizing his heart was in coaching professional football players. He became the New England Patriot's linebacker coach in 1980.
Parcell's first professional mentor was New York Giants Head coach, Ray Perkins. He reunited with Perkins as defensive coordinator in 1981 and slowly began his ascent towards legendary status.
