To sum this up.
Tyson had great (maybe the greatest) natural ability at a very young age, and lost it at a very young age. Hasn't looked good since Ammoto died.
I don't know why everyone thinks he's so big. I met him and he was about 5'10" 220 pounds and soft.
Roids will improve strength but not ability. Metyltest, if you could tolerate it, would be good the night of the fight but not as a regime. Actually, ephedra would be good after the 3th round.
I say fighters are dumb not to disparage them. I don't mean all of them, but lets face the facts -- University educated people don't become boxers. It's a sport of the poor and the poor tend to be less educated and the less educated tend to be dumb. And by the way, my dad was a top ranked pro welterweight. He went under the name of Rocco Rossano and had a record of 89-4. He was on his way to becoming the champ until a hammer fisted cuban by the name of Kid Gavalin ended his career. Boxing is the one sport where you're either the best, or you're nobody.
