Natural fighter vs. learned fighter.

[Samokries]

most of the attributes guys have mentioned improve HUGELY with experience

this subject is way over-blown

Agree.
Most of the 'natural' guys started boxing in highly competitive gyms/areas and went through huge amount of sparring early on (Toney) which got them to feel comfortable in all kinds of situations in the ring and to stay composed under pressure. Big bonus if they started training really young (Duran, Benitez, Whitaker).
On the other hand, if ‘natural’ means that a guy just likes to fight, than all accomplished fighters (amateur and pro) are ‘natural’.

I think a lot of punters assess this topic based on how a fighter looks

some fighters, just make it look easy... composed, relaxed, natural... reacting instinctively, without appearing to think about it

it took a LOT of training/experience to get that good

once you are that good, there are rules/"given's" that you can start to bend/break... I think that is a part of what people see as natural, but none of that is natural

This. Nails it.

Wilder has to be 100% natural in that he still hasn’t learned how to box, even some basic footwork

And the way he throws that bomb of a right hand you wouldn’t see in any text book

Hard to answer and seems relative to a question posed in history.

One could say Marciano. For natty. He is pretty much the clear king of overachievers in boxing. However, is there even a Marciano without Tommy Ryan and Jack Dempsey? Is there a Dempsey without Ryan? Ryan himself isn't even the man to make the crouching or being low in general tactic. It came from BK, well for him, and Ryan was the crossover guy to make it popular. The crouch actually comes from swordplay and was picked up in boxing from the beginning.

So is Marciano natural? Not really, just a mix of **** people don't associate with boxing. Hit me I hit you back harder isn't wrong to to, it's old. Forcing, moving your man, giving an opening because you believe you can hit back harder if you take one of theirs to do it isn't natural, it's just ancient.

His left is his shield, his right is his sword, he comes trained to slay dragons.
