I have to think Monzon in a bad mood wouldn't be someone you'd want to tangle with. It seemed like boundaries weren't much of a concern for him. Maybe I'd give a shot to Dempsey as well. anyone that can go to bars and repeatedly beat the toughest guy there, has to have a few tricks up his sleeve.
Tom Bogs sure caught Monzon on the wrong night....Carlos's son was sick and he was worried about him naturally, and wanted to get the hell back to Argentina quick....and I believe that if that fight wasn't stopped, he would have killed Bogs.
Don King's a good shout. Pistol-whipped a guy to death. Vincente "The Chin" Gigante had only two TKO wins in 25 fights, overall record 21-4. So you'd figure he was feather-fisted. But there's no doubt he was a dangerous man on the street.
Tyson would be a nightmare with his combination of speed and power. He'd be slippery coming in too with the bobbing and weaving.
