Smallest fighter you favour to beat 78 Ali-

He would knock him out very early, and why should we ignore the 60lbs weight difference? You said it like it has no impact on the fight. Mariusz Wach even now would defeat Greb inside of a round, Kevin Johnson now would defeat Greb inside a round, that's just how it is, you can't escape a 60lbs weight difference, I know people have beat people over 60lbs heavier, but that was when the smaller man was over 200lbs, but as the weight goes down, but the weight difference stays the same like if someone who is 140lbs fought someone 200lbs, it's no match, an ant fighting something 20lbs heavier than itself, it's no match

 

It seems that you don't know much about Greb's career then...

 

Do you seriously think he'd beat Mariusz Wach or Kevin Johnson, Just watch this footage sparring starts at 4:27

It was a spectacle for camera, not real sparring. He faced old, retired champion here - why would he try to hurt him?

Greb hurt Tunney badly and gave him the biggest beating of his career. I'd make Wach look clueless.

 

He's not throwing full power, but why would he intentionally look bad technically when he knows that is the only footage of him? That is him boxing as well as he can, I'm not slating him because there wasn't many people to copy or learn from, but not a chance he'd beat Wach who hurt Wladimir Klitschko

 

Marciano or early Patterson around the time of the Moore fight.

The picks so far are the ones that make the most sense. You would want to have guys who actually proved they could fight heavyweights in the real world. Walker, Conn, RJJ (although at 191 pounds he's actually heavier than Moore), Greb (but how comfortable can you be without film?) etc. might do it. But I dont think most of them would be favored. Certainly not enough to carry the cards of biased, pro Ali judges. Of that group, Conn is the best pick.

 

Marciano

Michael Spinks would come in bigger than what Marciano weighed

Dwight Qawi would weigh more than Marciano and was horrible against anyone with mobility once he moved to Cruiser- see the Ocasio embarassment.

Ali would probably beat him

Leon was a non stop punching machine that night. Underrated win.
