Add one attribute to a fighter that would make them hard to beat

The illusive George Foreman

 

Gerry Cooney - a fighting heart

 

Duran with Hopkins' dietary discipline.

 

RJJ with Toney's punch resistance

 

Terry Norris with granite chin.

 

Alexis Arguello with blinding speed would surely be unbeatable below 135

 

Liston,the ability to cut off the ring.
Loughran ,a big punch.
Marciano,accuracy.

 

Not sure if this qualifies but Sobriety for Tyson

 

Give Pernell or Floyd the freakish power of Julian Jackson.

 

Sung Kil Moon moar powa

 

Harry Greb with Deontay Wilder’s power

 

It fits. Let's call it Hopkins like dedication. We'd certainly find out what Tyson truly had that's for sure.

 

Hearns and Jones with granite chins were my first thoughts.

I don't subscribe to the theory Jones chin i was always weak, i think it was decent during his prime. Putting some serious iron in there tho makes the thought of him being beaten from 160-175 hard to actually fathom. As it is i would barely favor anyone over him.

 

Miguel Canto with more power in either hand. He has everything he needed to be the perfect out-boxer, but he needed something more to solve his stylistic issues. A genuine knockout punch would allow him to get respect when needed, and even save himself from unwinnable decisions.

A brilliant little technician was Kuniaki Shibata. He was athletic, explosive and well conditioned, with classy footwork and picture perfect punches. His major downfall however, was lacking a chin to match the rest of his parts. A Hagler like chin would take him to be among the very best featherweights in history.

Ruben Olivares was his own worst enemy, and he'd undoubtedly be known as the greatest bantamweight - and Mexican fighter ever - had he possessed the same dedication and consistency of Julio Cesar Chavez.
