Lots of matchups the last month or two featuring Tua, this is one that interests me. Given how highly Tua is rated in here for Power, Durability and Stamina i would not be surprised if he comes out on top in the debate.
Which Foreman? Late 60's to early 70's I like Foreman, but he could gas. Mid 70's I like Tua. Early to mid 90's, I like Foreman via decision. Tua was short, easy to hit, and I think lacked fire at times. He had limited range and was a below average boxer. Foreman's chin was decent enough to take a haymaker or two.
Tua try to come closer & fighting inside, try to land left hook.. suicide area.. vulnerable to foreman uppercut.. & foreman straight right.. tua survived ibeabuchi.. but i don't think he survived foreman..
Tua has zero chance vs prime Foreman. Sledgehammer jabs are followed by sledgehammer lefts and rights with Tua's back against the ropes. After five rounds the fight is stopped. Foreman vs Chuvalo all over again.
