Strongest HW chin ever?

I personally think a lot of Wlads shots weren't flush on the button or partially blocked, good chin no doubt but not amongst the top ATG chins. Good call on Mercer and vitalit

 

Chuvalo and Mercer

 

McCall sparring over 200 rounds with Tyson and not hitting the deck once is a good shout for best chin?

 

Mercer was old , but wlad floored him and then stopped him

 

Dave Allen
Joseph Parker

 

If the White Rhino takes clean bombs off Price without too much trouble, then he's in the top positions. If he does get the AJ fight for some reason and lasts 12 or gets a mercy stoppage on his feet again, he becomes ATG undisputed PED-proof chin.

 

And yet, he was KTFOed by a single left hook from Darroll Wilson

 

Vitaly Klitschko never been down ever and never buckled

 

I can on;y speak for the eras I lived through, I can’t honestly rate Chuvalo, Tex Cobb or others of eras prior.

That said, McCall has to be number one, he didn’t even keep his hands up while letting Lewis tee off on him in the 2nd fight, and never wobbled.

2. Vitali was the terminator

3. Ray Mercer

 

I like McCall too. Chuvalo fought more, but not as late, & Bonovena should have gotten a kd.
Also three hundred rounds sparring with Tyson.
Nothing ever put The Atomic Bull down, & he did not have the most elusive style, to put it mildly.

Nobody has stayed on his feet against as many modern sized HWs.

 

David Tua, Ray Mercer comes to mind
