Archie Moore vs Jack Dempsey heavyweight

But this comparison of resumes tells me that Gibbons really wasn't proven to be effective against elite heavies while Baker was.

Case in point... Gibbons expert boxing was rather easily deflected by Dempsey's manhandling techniques.

And I am not convinced that Gibbons' granite chin and durability, proven primarily at 175, are as highly rated when facing true heavies. In fact, the onus would be on the performances contained in his resume to prove this. And those performances are neither vast nor impressive.
