Action fighters who maintained their level of competition/peak for the longest?

Most truly front foot, action sorts burn out pretty quick. It's an undeniable and sad fact of boxing and it's a scene we've seen played out a thousand times before in boxing.

But what fighters just somehow kept on accumulating mileage without seemingly becoming shot, like most action fighters tend to become quite young? You look at the later or even mid career bouts of fighters like Ruben Olivares, Bobby Chacon, Matthew Saad Muhammad, you can tell they're well past their best. They might know what they want to do in the ring but they can't perform it, pull the trigger. They look their age even though they're really not that old. Just a lot of mileage, so to speak.

A really good and modern example of a fighter like this is Orlando Salido, who somehow seemed to even improve with age despite being an active fighter who's been in nothing but competitive and grueling matches for over 15 straight years.

Can you believe that Salido has the names of the old names the likes of Regilio Turr and Alejandro Gonzalez on his resume from his early years in the sport, yet is also so recent a fighter as to be the sternest test of multiple modern P4P phenoms like Mikey Garcia and Lomochenko. Incredible longevity for a fighter that more or less goes to war every time.

Your thoughts?

 

Greb was supposedly an almost impossible to find whirlwind of a fighter.

He doesn't strike me as a fighter that didn't have the skill to not be routinely absorbing lots of punishment. And really, how long did Greb even fight for before his disastrous surgery?

 

Basically looking for fighters who rumbled, brawled a lot... but had a long time operating at a high level of competition without really slipping. Basically, actions, FOTY sort of fighters who didn't become shot.
