I agree. It's possible Chisora would be 4th. You could mix around these three: Prime Chisora 39 year old Povetkin 283lb Ruiz There isn't a lot separating them, really. Some Joshua fans seem upset by this fact.
What "prime Chisora" even is? He lost every time he stepped up to the "AJ level". He definitely won't be a better win than Klit, Parker, Pov and Ruiz, probably on par with 2015 Whyte and 2020 Pulev.
Ruiz was better. And I think that version of Povetkin had enough to beat, even KO, Chisora. Whyte might have not have entered his prime yet but it's debatable. No. I don't think so.
Can you clarify when you felt he was prime? Just because someone is in their prime doesn't mean they are better. Take for example B Hopkins beating world champion Shumenov
I tend to agree. I don't think that version of Ruiz is much of a threat to any top 10 fighter of the past decade. It's not Joshua's fault; he did what he had to do. You can only beat who is in front of you. Nonetheless, Ruiz gained almost 25 pounds of pure fat in a matter of months and the value of beating him is diminished.
You can make a case for that. After 39 year old Povetkin it's all prime Chisora level or below (Whyte, Parker, 283 lbs Ruiz, 39 year old Pulev etc.) 39 year old Povetkin may have lost to prime Chisora too, though he was certainly more skilled and had more of a one-punch KO threat.
