Who do you think is the most intimidating Boxer of all time? Which boxer struck fear and terror into his opponent's hearts like no other? Some candidates: - Jack Dempsey - Sonny Liston - George Foreman - Mike Tyson Feel free to choose any other boxer if you like. Personally, I think it's Sonny Liston. George Foreman said he was wary of Sonny when they sparred. Floyd Patterson was scarred of him when they met in their fight. Henry Cooper said that he'd cross the street if he saw Liston walking towards him on the sidewalk. Hell, even Ali said that Liston was one of the few opponents who made him nervous before their fight. What do you think?
