No, that honor goes to Zab "Super Glass" Judah or Golota. The man in my avatar is also a good choice as he folded like an accordion every time he faced adversity.
I'd say Golota is still above our beloved Ear Muncher in that dept Nonetheless, Tyson is up there with the biggest mental midgets to ever grace the sport, the way he would quit against bums in the final stage of his career just further confirmed it.
I'm not arguing about Mike I really don't know so much details about his life. But I come from an eastern European country and believe me we didn't have to kill anybody to get milk home. It wasn't exactly easy and people are tough in our part of the world but that's it.
Would you tell Hitler to his face in his own house that ethnic cleansing is wrong? No? I guess that makes it fine.
A mental midget would not step into a ring with Larry Holmes, Lennox Lewis, Evander Holyfield, Michael Spinks, Razor Ruddock etc.
