Who was the most unbeatable at a weight class?

Yeah, Duran was so unbeatable at 135, he lost within six months after winning the title!

 

Usyk ---> Cruiserweight
Canelo ---> 168
Duran ---> 135
Mayweather ---> 130
Robinson ---> 147

 

Holyfield at Cruiserweight.

 

Joe Louis from 1937 to 1948

 

Unbeatable against all the other all-time greats in their weight class? Nobody.

 

Canelo at 168lb?

Gaping fanny.

 

Gomez at 122, though Garza, Negron, and Chandler if he moved up in weight would have given him a run there.

 

If we are picking one guy at one weight class during their actual career, it has to be Sugar Ray Robinson at 147. Following that would be the middleweight Carlos Monzon.

 

Michael Nunn at 160 around the time of the Tate/Roldan/Kalambay bouts

 

Armstrong at FW.
Fitzsimmons at MW
Borkorsor at FW
Argeullo at FW
Langford at MW
Charles at MW
Open for debate... keep well.

 

Jung Koo Chang at 108
Wilfredo Gomez at 122
Roberto Duran at 135
Ray Robinson at 147
Marvin Hagler at 160
Roy Jones at 168
Ezzard Charles at 175

None of them are unbeatable but very few boxers in history could beat them at their best in these weight classes.

 

Duran stands proud in the room as MoneyMay1 makes their statement, then looks a bit sheepish as Esteban DeJesus enters...


To my mind Duran is the finest 135lber ever, better at the weight than both Leonard (Benny) and Armstrong, he was that good. But no one is unbeatable, and on a given night even the best can slip up as DeJesus showed, almost twice...

 

Depends on how fine you want to split hairs, but the DeJesus loss was over the weight at junior welter (couple of pounds over lightweight really) in a non-title bout.

For some fighters a change in weight division by only a few pounds over their best weight can make a difference, Wilfredo Gomez being one prime example. We of course saw an older, more mature Duran succeed at higher weights but at this time it might have been the difference between being a perfectly-tuned machine and one that runs really well.

Sandy Saddler was nearly unbeatable at 126 for a long stretch, in my estimation. That one loss to Willie Pep throwing his ‘perfect game’ means he wasn’t completely unbeatable but otherwise his losses once he matured into his prime pretty much came above that weight (and to good fighters). I think that couple of pounds edge was a big difference to him (maybe he just didn’t have to starve and thus wasn’t as mean, haha).

So I’d still wager that Duran at 135, Gomez at 122 and Saddler at 126 were about as close to unbeatable as could be at a weight (had they strained to stay at those weights in their later careers, however, the drain of making the division after they had outgrown it would have shown sooner or later).

I’d put Roy Jr in the same company at 168.
