Marvin Hagler had a very visible mean streak. He looks mean when he's happy. Not the kind of guy I'd want to make angry at me in the streets either.
Roberto Duran was mean,Dempsey was mean,Tyson was mean,SRL had a smile but was mean (Dave"Boy" Green..Andy"the Hawk" Price) Foreman was mean (early George) Sonny Liston had a mean look and beat Patterson Mean...Marciano was quiet but did you see the quick left after the suzie -q on Walcott....Kelly Pavlik seems like a nice guy but he has Killer..
