Ortiz. He's a lot better. Williams could punch, but against a fighter of Ortiz's calibre, he would fold.
It's clear you haven't studied either the record or the tape. Ortiz was in a different class than Williams.
I wouldn´t call Street Lethal indirectly stupid, only because he says that Ortiz was in another class. Ortiz was very consistent and beat the better fighters, and he had no real weaknesses...
And Williams had lots of weakness and had the **** beat out of him several times on account of them. He couldn't take to the head or the body. Ortiz would have administered a severe beating to Williams. People are way overestimating Williams' chances here, to the point of absurity, to be honest about things.
