he had an unexpected loss to buster douglas and that sent him off the rails,went to prison for three years and never recovered.

This is what seperates a legend from a non legend.The ability to cope with adversity and loss.Tyson gets knocked out and couldnt get his head together again.Ali came back time after time ,again and again.So did Evander Hollyfield.Tyson is well down on the list of boxing legends.

Marciano was unbeaten and was fighting heavyweights at a far lighter bodyweight.
Ali came back again and again to prove he was the greatest.
Jack Johnson fought and beat whites at a time and in an era and place where blacks were hated.
Max Baer could get back up again and again.
An old guy called Bonecrusher Smith destroyed Bruno and earlier took Tyson the distance.
Paterson,Dempsey,Louis all proved that they can fight anywhere ,anyone,anytime.

What did Tyson come back from?He beat Bruno?Big deal.Bruno was a slow useless slob.Tyson had no heart,he proved this over and over again in that once he was beaten he never recovered.

no heart = no legend,
