Which active fighters, will we remember fondly, in twenty or thirty years?

Chocolatito, GGG (if he still counts as active since he hasn't officially retired), Inoue, Ioka, Beterbiev (I think he'll be used in LHW fantasy fights more than anybody since Michael Spinks going forward), Lomachenko, Pacquiao (he still wants to fight Barrios so still kinda active), Tanaka and Teraji are both all-action types so will inevitably be well-remembered, Estrada probably. And a few gambles now on Tim Tszyu, Janibek Alimkhanuly, and Junto Nakatani who I think will all go down with very great careers.

 

Canelo. For the future generations studying the game ? Canelo will be the big one.

It goes different ways for different generations. Our generation don´t like Canelo, but I see the future generations looking at his record, his performances, and being impressed.
Look at what happened with Ezzard Charles, he wasn´t ranked as high as people that never watched him live do, today.
The future generations will look at Canelo´s record and be impressed. I think Tank Davis will be the same story too.

Lomachenko will be viewed as a great amateur but his pro record will not standout, nobody will know who Kambosos or Luke Campbell was. And it will be easy to diminish the Rigondeaux win.

Usyk, as a HW, tough to say, his resume depends on what happens next with Joshua and Fury. His win over Fury particularly will lose value with time... but he is very well liked so it will be a debate between guys that watched him live and the new generation that will most likely not be impressed by the Fury, Dubois and even maybe the Joshua wins.

Inoue will not be talked much outside of the hardcore little weight fans, ...
Crawford, I don´t know.... the lack of charisma he has will hurt him, he won´t be remembered IMO, he will be a Andre Ward type.
Beterbiev wil be forgotten... too inactive, fighting guys that are out of the limelight, I actually don´t know any of his opponents outside of Smith just because he was the guy that knocked Hopkins out of the ring.
