Which fighters would have benefitted the most from not being nuts?

Simple question. For example, both Golota and Ortiz were/are both talented boxers who have underachieved because, well, they're both of unsound mind. Who do y'all think would have been a better fighter/achieved more if they didn't have such obvious mental limitations? Feel free to throw out other shouts as well.

 

Good one. His chin was superhuman, for sure, but I think his problems were more drug-related than inherently being nuts. He was erratic for sure, but I don't know how much better he would have been if he were a little more normal. I mean, McCall had fits with an ancient Larry Holmes and was outboxed by Frank Bruno, so I don't think he had a super high ceiling that he failed to realize. I think he came close to realizing his potential (though a sober McCall absolutely doesn't break down in the ring and start crying against Lewis.) atsch

 

Well, their personal lives, sure (one wouldn't be in jail, the other would still be alive). But I was thinking about the question more in terms of how a fighter's mental state affected their in-ring performances. Ike and Valero were certainly nuts, but they didn't show ill effects in the ring like Golota or Ortiz did/do. Perhaps I should have clarified this question better at the start. My bad folks atsch
