Why are elite fighters rarely stopped by body shots?

BELLY

 

Most body shot stoppages that come to mind seemed like possible quit jobs.
The one exception I can think of is the ko Roy scored over Virgil hill.

 

Because the damage to the body is done by accumulation , rarely one punch kill shots.
You might be able to tough it out with a single brutal body shot landed on you...but a headshot just turns off the lights no matter how tough you are.

the best of them break you down with body work....and officially 'KO' you to the head

But also, lots of fundamentals are disappearing in today's fight game. Few guys know how to parry shots anymore or punch on the move. To a lesser extent (but growing) is the ability to fight on the inside, and the art of elite jabbing is diminishing. But also I fear that good body work is diminishing ....becuase instead of learning it, it's just deemed too risky.
