WK was never undisputed and i would say he's an ATG like Sven Ottke and Arthur Abraham are ATGs. Both have impressive stats on paper throughout the course of a career , but none of them proved their greatness in the ring. King Arthur has 18 world title defenses across two weight classes.. Did you know that? I don't think there's much between Arthur and WK on the ATG list tbh.
That old holyfield was the ibf, WBA unified heavyweight champion at 36 years old in which holyfield wasn't declining. That version of holyfield is better then any fighters wlad has beat. I give you a decline Mike Tyson but between byrd or tyson who the fans want Lewis to fight with? Hmmmmm. Green Vitali? LOL That green vitali is better than any fighters his younger brother wlad beat. Byrd is lucky vitali had a torn left shoulder when they fought each other.
