Tua by a brutal 2nd round knockout. Maybe even first. Harry Greb is arguably the greatest fighter ever. But he does not have the power, height or anything else to keep Tua off him.
Very interesting matchup, me personally i think that harry should outbox him based on their records and ranked fighters that they fought.
You’re right, I wouldn’t pick Tua to KO Mike Tyson in seconds, I’d pick Tua to KO Mike Tyson in nanoseconds.
There's a reason they called Mr. Harry Greb "The Lennox Lewis Of The Plains" back then. I don't know what the reason is. It may not make sense. It might be a temporal paradox situation. But they did used to say that in my timeline, before the Borg got involved. I don't know about now.
A Corbett vs. Tua thread you say, huh? Wow. I wonder how many guys Greb fought who could hit like Tua. The mass x acceleration that Tua brings would probably be unlike anything Greb ever had to deal with. Just feels inevitable that Greb winds up in a horizontal position, probably involuntarily blowing spit bubbles or something.
