Think of it this way, Fury is in the Ali role, Wilder is in the Frazier role, AJ is in the Foreman role. Fury would have beat an ATG twice to establish himself (Ali beat two lesser ATG's three times), in this scenario would have fewer initial title defenses before facing another "ATG" (someone who goes on to be an atg in this scenario) in Joshua. Then loses to Wilder. At that point, his resume is comparable but somewhat less than Ali's at the time he lost to Frazier, about equal on atg wins, but fewer defenses. Meanwhile, Wilder at that stage would have about as good a resume as Frazier did at the time he beat Ali, at that point, he'd have more title defenses over a longer period of time, with a win over one ATG. Then when AJ beat Wilder, he would be comparable to Foreman, slightly worse resume because he already has the loss. Fury comes back, avenges loss to Wilder (ala Ali Frazier) and beats AJ again, and has another 7-10 successful defenses, retiring without another loss, along with beating another future ATG. So, he'd have somewhat fewer, but still very comparable, number of title defenses as Ali, at least as many ATG wins, a dynamic, redemptive storyline arc like Ali, but retire on a high note instead of a low note. You could easy make an argument he's GOAT at that point. Just keep your mind open. Chances are nothing like this happens, but its at least envisionable now.
Got it, you hate Fury and Wlad despite all evidence of their accomplishments. Problem is, most people don't share your delusions. Wlad has the resume, and Fury beat Wlad. That makes them 1 and 2 until proven otherwise in the ring.
