How does Louis stop him? I would argue that Chuvalo who took the hardest flush punches Foreman could muster without going down he could handle Louis's power. Yes I know he may have gone down when knocked into the ropes but he was lucid and clear headed when it was stopped. Frazier landed a beautiful hook on the perfect spot forcing Chuvalo to turn away and wave Frazier off other than that Chuvalo looked like he could have manhandled frazier with a little more speed.
Just because of Chuvalo's insane chin, likely "just" a UD. The only hope Chuvalo had against Foreman was the latter exhausting himself. Which would have taken several more rounds. By that time if somehow Chuvalo was standing upright, he would have absorbed an unimaginable beating & damage.
Louis adds another "First Time Ever KOed" victim to his resume. There were lots of durable guys who were never stopped until they tried to stand up to the Brown Bomber's combinations.
Title of the thread should be 'How many rounds does Chuvalo last against Louis' - to which I would say about six or seven, after absorbing a severe beating and with the referee or Chuvalo's corner putting an end to the fight.
But Chuvalo would go out that night, dancing with his wife while Louis remains in his hotel room, raw steaks over his battered and badly swollen hands, having been forbidden from going out and risk being seen socialising and having a good time with his own kind.
This would be an interesting fight I'd certainly expect Louis to win it but its just a matter of how he wins it. I think Chuvalo could potentially go the distance and give Louis a tough fight but I also could see Louis being able to stop the iron chinned Chuvalo with one of his picture perfect combinations likely would take an accumulation of many of these combos landing to either put Chuvalo down or force the ref to stop the fight.
I think if you take enough clean punches off Joe Louis,which Chuvalo would. Then I don't care how formidable your chin is you're going down. It's as simple as.
Again different eras, but Chuvalo can't win this, the only question is how its going to end. George could press and maul early on but simply didn't have the savvy to even come close to stopping the Bomber. Outside of the Quarry anomoly what contender did George ever stop? No Doug Jones comments please. To George's credit, he never really bled in fights, so a UD is entirely possible. But a more logical ending would be Louis's protracted attack which would, by the middle rounds, have George without a clue with the ref stepping in and stopping the proceedings mid to late rounds.

George has always protested that like LaMotta, he was a far better defensive fighter than given credit for. The fact that both have lived so long since retirement with their marbles intact bears witness to that. Neither flinched, so they could always see the punches coming in time to move that fraction of an inch necessary to sufficiently reduce the impact. Yes, I think Chuvalo does go the distance with Louis. Joe liked to get the other guy to lose patience and make a fatal mistake. There were other guys who tried surviving by running on him. George does nothing like that. He's not going to retreat like Schmeling did in his rematch with Louis, giving Joe the chance to tear after him, he's certainly not going to run like Pastor and Walcott, nor is he going hell for leather on the offensive like Galento and Max Baer. Chuvalo will be what he is, a Croat-Canadian Gibraltar, inexorably moving slowly forward while Louis boxes on the retreat. Joe was certainly at his best shuffling forward, stalking his man as an aggressive counter-puncher, but he did have the skills to win by boxing and giving ground behind his jab. Once he realizes that he could risk injury to his hands by attempting full force on George's cranium, I think he and Blackburn likely accept the option of an easy decision win. Chuvalo's not low enough to allow for the Godoy II template, and he's too controlled for offering a Max Baer/Tony Galento type victimization. This one stays in the middle of the ring. Louis didn't have the one shot power necessary to ring George's bell as needed for creating a finish opportunity, and I see Joe moving back if either gives ground, diminishing the Bomber's power. Blackburn and Louis take the minimal injury risk in opting for a wide decision win. Chuvalo acquits himself honorably in a solid showing with little drama, and I think the fans go home satisfied rather than disappointed. I suspect this is what Louis-Uzcudun might have looked like when Paulino was in his prime [which we saw with Harry Wills].
