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."

But if they took 15 mg of Dianabol a day for five weeks -- Mix says it might have been three weeks, Shea says six -- it could have given them an advantage, especially if none of their opponents was using. Victor Conte, the BALCO mastermind, says a cycle of that size and length could have given them benefits for "four months or longer." But Charles Yesalis, professor emeritus of health policy and administration at Penn State University and a leading expert on doping, says such doses of Dianabol might have given the players a boost for only up to two months.
