So let’s imagine that we went back to the original 8 weight classes and 1 belt per division. Rate your top five in every division. I know that some people may be hard to figure out if they would go up or down in weight, but just do your best to be realistic.

Flyweight
I’ll be honest, I don’t know enough people at those weight classes to make an informed opinion.

Bantamweight
Inoue
Nery
Estrada
Wangek
Rigo (I think he is probably still good enough)

Featherweight
Santa Cruz
Warrington
Russell
Stevenson
Navarrete

Lightweight
M. Garcia (I think he could still make the weight)
Loma
Davis
Berchelt
Easter

Welterweight
Crawford
Spence
Pacquiao
Prograis
Taylor

Middleweight
Canelo (as much as it pains me to say)
GGG
Jermall Charlo
Jermell Charlo
Andrade

Light heavyweight
Gvozdyk
Bivol
Kovalev
Beterbiev
Benavidez

Heavyweight
Fury
Wilder
Ruiz
AJ
Usyk

The main problem is that I don’t see most of the good fighters to be able to drop down into the lower weight class. Most of the bigger fighters would just have an advantage. Maybe there are some I missed.
