Holy crap!

If I had to name some of the most violent punchers in boxing I would have to say Mike Tyson for breaking Jesse Ferguson's nose with a fifth round KO thanks to one of his signature uppercuts. Joe Frazier's gotta be in there for decking Ali in the 15th round of the Fight of the Century with a left hook that broke his jaw and caused a cheek haemorrhage although Ken Norton later caused the same injury against the Greatest. The only other guy I can think of is Jack Dempsey who beat Jess Willard so severely he fractured his cheek and left the guy looking like he'd been in a car wreck.
Who would you say are the fighters that produced moments that made you say Damn!
