George Chuvalo. Made through over 90 pro fights without ever sustaining a single knockdown. Was stopped on his feat only by Foreman and Frazier.
Aren't Uzcudchin and Chinvalo considered the top two chins in HW history? Shavers has got a Lennox Lewis sorta chin where whether its a weakness or not its sure as hell not a strength.
Chuvalo had the best chin but Green a great one too. Tyson hit him with some sick punches but Green never went down.
Why is Shavers on there? And Green for that matter? He faced one of the best punchers ever in Tyson, but doesn’t have much else on his resume. Chuvalo faced a long long list of world class heavyweights who could punch, including the guy with maybe the heaviest hands ever in George.
