Tua needs no steroids to be that big. Walk around New Zealand and you'll see dozens of Samoan guys huge like that!!
Holyfield by a UD, he's more accomplished than Tua and he'd fight the same way he did against George. Could be some rocky moments though.
Holyfield wide but competitive UD. Holyfield was the better mid/shirt range fighter and would outbox and outwork Tua, although Tua would have his moments being the more powerful fighter, hurting Holyfield at times.
They sparred plenty. Tua was no joke... very strong, very durable, and big punching power in both hands. He also had decent hand speed, stamina, and punch output when he was at his best. It would take more than that to beat Holyfield. Holyfield by clear decision but Tua has some good moments.
Tua was down vs. Rahman (as the bell was ringing and it did not count) and Barrett. Tua wasn't seriously hurt vs. anyone though. Holyfield was down vs. Cooper (needed the ropes), Bowe (needed the ropes), Bowe x2 more, Ruiz, and Toney.
This is easy. Holyfield and its problably not even close. Ike fought an absolute prime Tua and beat him with out half the skills EH could bring to the table. Sure Ike was bigger but chin and output is what led him to beat Tua. EH had chin, output and skills in spades.
Sorry man, this is mostly misguided & wrong. 1) Some of those men used. Others like Tyson & Tua were big young (Tyson by 13, before lifting, por boxing, & with no access to PEDs nor reason to take them). 2) Hearns was tall & long, was underweight at WW, & there is no evidence he must have or needed to use them to finally reach 190. 3) It is unfair & irrational to assume most everyone used. Though many dabbled, & some used regularly or many courses over some years. 4) The health consequences for using steroids & related drugs are extremely well documented. SO many of the just body building stars from the 60's & beyond died young or very young. Often from heart, kidfney &/or lover problems. There can be no ethical double blind studies to determine what levels & endless combinations of PEDs, HgH & potentiators are how dangerous to who. If you insist that science reserves judgement upon whether they are dangerous...That radical posotion severely compromises your credibility on the whole subject. 5) Making you short for your division? That is mistaken on two levels... A) If you are strong enough to get a big power, energy & punch resistence advantage, it is so often worth the cheating. And usually is worth being shorter-though there are steroids that maximize strength WITHOUT adding much muscle mass so will not even make you effectively shorter, like Alex Rodrigues took-did you know any of hat that man? Though I am deeply against it & how it steals money, glory & success from honest men. B) The height & length question does not apply at ALL if you already were fighting at HW like Holyfield & Tua were! I hope you can be the fairly rare person who can admit when they are wrong on some demonstrable facts.
