Great chin but I wouldn't put it over McCall or Chuvalo or Ali. Holyfield floored him and Wlad Floored and stopped him. Still he has cast iron in there to take the bombs Morrison threw and Lewis
The fighter with the best chin ever may have been journeyman Marion Wilson. He fought everyone ... Hasim Rahman, Oleg Maskaev, Andrew Golota (twice), Ray Mercer, Shannon Briggs, Ike Ibeabuchi, Kirk Johnson, David Izon (twice), Jeremy Williams, Frans Botha, Oliver McCall (twice), Jimmy Thunder, Derrick Jefferson, Tyrell Biggs, Greg Page, Carl "The Truth" Williams, Larry Donald, Tony Thompson, Paea Wolfgramm ... Fought 57 times, only won 12 bouts ... and was never stopped.
It's right up there. Tex Cobb, Marciano, Chuvalo, Hagler, McCall all equally as good. Don't forget... Ross Purity had a granite chin also. Very underrated in that category.
If we're expanding this discussion beyond heavyweight, I'll throw in Hector Camacho. One of the best chins ever and tested by some major punchers.
No, though he was way up there. Taking bombs from Morrison like that was sickening. Also took an absolute shellacking from Lewis, Cooper and Wlad. Grade A chin for sure. Personally I'd put McCall up there for greatest ever chins. Wilson deserves a mention as well.
Mercer's chin is one of the best of all time but I think it's just below ones such as McCall's, or Chuvalo's
Mercer's chin is definitely A grade. P4P it may be better than that of bigger guys like McCall and Ross.
