For me, if I’m building the prototype fighter before I even get to skills, ability, or boxing IQ— the most most fundamental thing I want in spades is toughness. Meaning mental toughness and physically toughness. Combat sports is one of the few avenues in life that will sometimes allow you to witness someone’s “spirit.” In boxing, they call it “fighting spirit. You aren’t going to be a great fighter if underneath all your ability and know-how you aren’t a genuinely tough person.
Additionally, I will say great fighters just have another level they can tap into. Sometimes, that occurs against other great fighters and sometimes it doesn’t. I’ll give two example and they both are Roy Jones fights. When Roy Jones fought Clinton Woods, he was actually having some success against Roy early on. Mind you, this is relative to what success looked like for Jones’ opponents back then. However, Roy then started fighting at a level that Woods just couldn’t match, and eventually he landed some big punches and the ref stopped the fight. It was a big windup overhand right if I recall correctly, and the ref stopped it. He started the fight mediocre by his standards, and then turned it on mid-fight. To me, that’s an indicator of greatness. It’s like a NBA player going 0-10 the first half and then dropping 40 in the second half. To be able to flip that switch on your ability on command is some next level shyt.
Second example, when Jones and Tarver fought for the first time. I won’t get into the coming down from HW stuff and all that. Ultimately, it was a RJJ fight or performance we weren’t accustomed to. The last few rounds Roy needed to dig deep in order to win, and he did just that. He tapped into that 5th dimension to pull that fight out the fire.
Greatness for me isn’t just accolades: it’s a combination of things. How you fight, who you fight, how you look against who you fight, how you respond to adversity, mentality (you on some take on all comers shyt, or you’re trying to cherry pick), etc.
