Indeed, the man whom ESPN would later find a "violent, combative player known for his short temper" inspired the league rule against throwing a helmet after having done so himself to an opponent's helmet.  Peter Alzado, Lyle's brother, later identified the years of their youth—marked by an absent, alcoholic father and an over-worked mother—as the crucible for Alzado's unremittingly fierce style of play. "That violence that you saw on the field was not real stuff," his brother held. "Lyle used football as a way of expressing his anger at the world and at the way he grew up."  Defensive end Greg Townsend , a teammate on the Raiders, contended that the savagery for which Alzado became noted represented only part of a "split personality." "Off the field," remembered Townsend, "he was the gentle giant. So caring, so warm, so giving."
