I don't think he comes out undefeated. Think he goes 3-1 and Rahman takes one. Could see him going 0-2 against Rahman and beating McCall twice.
Potentially, yes. Anthony Joshua could beat each of them without getting a loss. But I also think Lewis could beat Andy Ruiz and Oleksandr Usyk without a loss too
He could beat both. but McCall and Rahman could punch a bit, especially Rahman with that long reach, so if he gets hurt maybe not.
I think he beats both. Neither Rahman nor McCall were extraordinary punchers. They just caught Lewis by surprise. Joshua has been stopped twice. The first was from a left hook to the equilibrium vs Ruiz. He never recovered after that one left hook and that one punch basically ended the fight. The second stoppage was vs Dubois who is a bigger puncher than either McCall or Rahman. I can see a scenario where McCall or Rahman land a punch to a vulnerable spot, like behind the ear which is what Ruiz landed, they could stop Joshua. But i doubt it. Neither McCall nor Rahman were particularly known for the left hook. Of course its possible for them to ko Joshua if they land the perfect punch but i doubt it. I think someone like Tua or Ruddock would have a better shot vs Joshua than they did vs Lewis. Joshua is less likely to be stopped vs above average punchers like McCall or Rahman but probably more likely to be stopped vs enormous punchers like Tua or Ruddock.
Yes and he most likely would, but no more likely than Lewis, which means that if he also switches off or doesn’t take them seriously, he could lose.
