Miranda (is he considered a villain? He sure talks a lot of shit)
Mayorga
PBF
Liston (I'm reading a biography about him, The Devil and Sonny Liston, good book)
Ali
Young Foreman, Old Foreman is one of my favorite "good guys"
Is Malignaggi a villain? I know he's not on the level of a Foreman or a Mayorga, but he's another trash-talking conceited son of a bitch who a lot of people would like to see KO'd
