New York (CNN) — After he graduated from college, Frankie Edgar began working for his stepfather’s plumbing business. He woke up early each morning to dutifully trudge to job sites around New Jersey on the hottest and coldest of days. In the afternoon, Edgar coached wrestling. At night, he treated himself to training in his true passion: mixed martial arts. Soon Edgar told his family he wanted to quit plumbing and become a professional fighter.
