My vote goes to either Toney or Judah. They try to hide their one digit IQ behind quick remarks in the mould of Beetlejuice. The Beetle or Toney.... is about the same level of intelligence. [ame]http://www.youtube.com/watch?v=C4m9i-9RksI[/ame]
Mayweather clearly isn't dumb. Dunno why people are saying this. As one already pointed out, he's just really immature. His father and uncle on the other hand, are thick as ****. Especially Roger. A cretin of the highest magnitude.
Yeah, Floyd isn't dumb like some other guys. He also isn't very intelligent... but if he matures a bit he'd be ok.
Galota is certainly on the dais when it comes to this 'honour' and probably the guy occupying the middle step.
How about Sonny Liston? Couldn't read or write, worked for the mob, made a mess of his life. I don't want to put him down, because he didn't exactly have an advantaged background but there it is. Otherwise Ibeabuchi might be an option.
they say insanity is doing the same thing over and over, but expecting a different result each time. i.e Roy Jones getting KTFO over and over
It could be argued Liston did very well for a guy from a disadvantaged upbringing who couldn't read or write. It didn't end well though.
Saw a vid just the other day of Kirkland beating the hell out of one of his sparring partners. Even continued hitting the guy well after the round was finished. Totally braindead ****.
