Lyle Martin Alzado was an American professional footballer, recognized as one of the top defensive linesmen of the National Football League. Born to absentee father and overworked mother, he had a very troubled childhood, which made him highly aggressive, which in turn led to numerous brushes with the law. However, with the help of his school football coach, he was able to drive his aggressiveness towards the game and established himself as an effective defensive linesman. Continuing to play throughout his college years, he soon started taking steroids. At the age of 22, he was picked up by Denver Broncos, remaining with the club for the next seven years, thereafter being traded first to Cleveland Browns and then to Los Angeles Raiders, eventually retiring at the age of thirty-six. Concurrently, he also worked for the betterment of the youth, setting himself as an example. He died of brain cancer at the age of 43.
