We all know Andy Ruiz was trillions of pounds overweight. Check here too: https://www.boxingforum24.com/threads/154lb-andy-ruiz-jr-vs-roberto-duran.642029/ As both of them are pretty much the same height and carry about the same lean body physique @154lb, do you think a modern fat (MF) Thomas Hearns could´ve been HW champ of the world today? Does he beat AJ like the 154lb lean + 110lb fat Ruiz did?
On the other hand that means 154lb Andy Ruiz would be granit chinned here, or even @160. He´d go toe to toe with the likes of Hagler or LaMotta with less problem.
Is hearns getting shot with a reverse shrink ray that's making him a giant or is he just morbidly obese? A hearns as big as wilder would murder everyone he fought. Fat boi hearns wouldn't be able to move or set up shots and would have a heart attack if he somehow made it to round 5. Plus his chin wasn't good for a middleweight, a heavyweight would only need to tap him.
I don't know. How would a dedicated professional fighter with pride and self respect like Tommy let himself go enough to come into a fight in a disgustingly obese shape like lard arse Ruiz (after a "training" camp mind you) did? I doubt it's even possible to suspend disbelief to ponder this. It's like imagining Ruiz coming into a ring with a 6 pack (abs that is, not bottles of chocolate sauce for between rounds hydration). It could never happen.
Modern "Big daddy" Tom Hearns would nearly be twice the weight but as stated this would be modern mass added to his once gnarled frame not ordinary fat mass this would come from MoDeRn SuPpleMenTs and MoDeRn NuTrIeNtS he would be gaining nearly six feet in height to accommodate for TWICE the modern mass because we all know modern nutrition and supplements are why modern athletes are so big. It's why boxers before the Klit era where so small on average Hearns was a six foot one tall nutrient depreived skeleton from the 80s give him what all these pampered babies have in 2019 from birth with a 80s mother with modern nutrion and this man would grow at a spotanious rate it's just science. I believe the 12ft2 268lbs Big Daddy Tom is quite possibly the heavyweight GOAT just my 2€...
All joking aside, anyone who really thinks that Ruiz would be 154 if he was lean like Hearns is delusional. He would be between 175-180 lbs. with NO bf. At 154 he would lost a lot of muscle. Which still means he was very fat for his fights with Joshua. But he obviously has much more muscle than anyone at this weight-even accounting for rehydration & a 10% heavier real fight weight.
A 147 lb Hearns could definitely hurt Joshua. When Ali came back to fight Larry Holmes in 1980, he sparred with Hearns and Hearns was able to rock him. Still, facing a 240-250lb Joshua, Hearns chin wouldn't be able to hold up and he'd get ko'd early.
I don't see the comparison with Andy Ruiz and Thomas Hearns. Height is about it. Andy holds the higher weight much better than Hearns ever could.
