There is no way that anybody is landing on Greb on a consistent basis. Guys like Tunney and Walker could hardly even hit him flush. You have to look at what Greb actualy did and what it means. Greb was never KOd in 300+ fights despite fighting dozens of times a year up to heavyweight. He beat bigger fighters than Monzon, better boxers, harder hitters and arguably a couple of fighters who were all three.
So, there's always a first time. And I didn't say KO, I said stoppage. If Monzon landed in the right spots he definetely could hurt Greb and then follow it up.
Monzon was not your run of the mill great, nevermind a run of the mill fighter. He would have handed the shorter, smaller, onrushing Greb a methodical beating, starting in about the 6th or 7th round, and would have treated Greb with respect and would have taken no chances up to then. The referee either stops it due to Greb's good eye being damaged, with a knockdown or two just prededing the stoppage.
There is probably only one MW in history who could have beaten Monzon. Greb happens to be that guy. Greb UD Monzon
That is just the point ironically. He would be on Grebs resume!!!!!!!!!! If Greb were fortunate enough to beat Monzon then it would be by no means his best win or toughest asignment. Perhaps barley one of his top ten wins. The best fighter Monzon beat would sink into Grebs resume never to be seen again. I dont want anybody to underestimate the magnitude of what Monzon is up against here.
That doesn't fly. First of all, Foreman and Frazier are heavyweights. Heavyweights punch harder than they can take, compared to smaller weights. Second, Foreman had a solid 15 pounds on Frazier. Well, since Frazier was overweight, the difference was somewhat less, but it's awefully clear that Foreman is the bigger fighter. Third, Monzon is not in the class of Foreman in terms of power, pound for pound. He was a good hitter (especially earlier in his career), but not a devastating knockout artist. Fourth, although i don't really see how Monzon is bigger than Greb, even if he was, Greb beat up nearly all significant lightheavyweights of his era, sometimes even heavyweights! Monzon never did anything above his own weight.
While i wouldn't argue a Greb can't win this i have the feeling you are very much going wayyyyyy over the top with your descriptions. A Monzon not even competitive (wouldn't be fit to be his sparring partner the way you are going on about it) vs a fellow middleweight? Gimmee a break.
The same way he did with any other boxer who tried to run a jab game and box him at a distance? If he could do it to Tunney, he could certainly do it to Monzon. Greb is a bad matchup for Monzon.
Both great fighters....I have looking a Monzon's films lately...not real fast...but never really stops throwing punches. Attached is a copy of BoxRec's fight history on Greb. http://www.boxrec.com/list_bouts.php?human_id=9019&cat=boxer Greb fought and beat good / great fighters as big or bigger than Monzon. (Tunney, Delaney, Loughan, Slatterly, etc.) It might take several rounds to do it, but Greb would get inside. Greb to some degree might be what we call a supermiddleweight today (was fighting MW's and LtHvy's). Even fighting with one good eye, I think Greb could decision Monzon because he is physically much stronger than the contenders Monzon met, especially Napoles and Griffith.
I need to backtrack a bit here. I do consider Monzon to be a top 5 all time middleweight and I dont doubt that he would likley still be considered such if he had fought in Grebs era. I also consider him to be perhaps the best middleweight of the postwar period. Greb however is just off the scale in terms of resume at middleweight. I honestly dont think that any middleweight in history could present him with something he had not tangled with before.
