Could any 80s contender have been the GOAT with perfect management and drug-free dedication?

They shared an era with the best versions of Tyson and Holmes. They would inevitably need to beat at least one of them at their best, preferably both, to be considered the GOAT.

Even with the best management, discipline, and no drug/alcohol issues, I can't see any of the lost generation pulling that off. Gun to my head, maybe Witherspoon could pull off something amazing but I doubt it. He had so many close calls with guys like Thomas, Tubbs, etc so there's no guarantee he beats a prime Holmes. The fact he was KOd in 1 by Smith doesn't give me much confidence in his chances against Tyson. Thomas had the right combination of size, skill, and ability, but I would not be confident that he could win the majority of fights against all the 80's guys.

I'm not saying they would need to be undefeated, but they would need to beat the majority of the 80's guys convincingly (no dubious SDs or MDs) or at least win a rematch while also beating Tyson and Holmes. I don't think this an unfair criteria to set given how weak the era could be at times. If I wanted to be harsh I would demand that they also beat Holyfield and Bowe in the early 90's.
