Urtain sure looks like Marciano style and all As far as dimensions Bobby Czyz was similar in stature but not as heavy. Short smaller arms and larger legs, long torso A younger Tua 200/210 before he got heavier was about the stature of Marciano his style reminded me of him, the same goes for Tyson as far as stature.
In name and body shape - Rocky Graziano. Squat, powerful rounded shoulders and thick back, not overly muscly or defined but a workhorse.
There have been quite a lot. And they all fought over 190. Dave Zyglewitcz. Al Ettore Gus Dorazio Tom Heeney Red burman Orlin Norris. Tony Musto Melio Bettina Tom sharkey Steve Dudas George s**** iron johnson David Tua (before he developed 1990s physique). Tami Mauriello was over 190lb by age 20. Brian minto. John L Sulivan Denis lebedev Light heavyweight Frankie Depaula and Tony Oakey were quite close in the same odd proportion department.
This a really great list, I don't remember Tua when he was only around 200 pounds, I will have to look him up and learn more. Urtain developed his physique enterring stone lifting contests in Spain. His whole family was good at that, including his sister. I guess he had incredible genetics.
