First, Tyson has loads of inherent talent, but to suggest his people didn't have him using certain compounds at various stages of his career is plain lunacy.
I'd suggest most of Mike's aggression initially came from his being, as has been said, an emotionally troubled young man with serious issues. Add in the drugs we all KNOW run rampant in boxing, and there ya go.
Check out the man's demeanor now, as well. He is either on boatloads of meds to keep him "stable" and "controlled" (certainly he is on depression meds, etc.) or his years of using androgen-type drugs has left him somewhat docile due to their suppression of his natural physiology (plus age, of course).
Again, make no mistake, Tyson was a bonafide beast, but to deny realities of that world is folly.
Big money is king and whatever is required to maintain the big money is a given.
