I'm not inflexible; the shots have me sold on him in the top 5. Not great size but the quality's unmatched. That means putting him ahead of Oliva, Fox & Nubret. Debatable but he looks great.
Oliva is easier.
Nubret is close-similar to Haney-athletic, cut to ribbons, not so big. A toss-up but Haney might have an edge in size.
Fox definitely bigger, not as cut or refined-another toss-up; goes either way on the basis of taste. Someone with more size generally has an edge though IMO.
To put Haney's chest over Nubret & Fox is subjective, more a matter of taste.
