Don't really disagree with most of what you said. People have personality quirks that may come with certain advantages and disadvantages. And going a 100% every training is gonna be a quick way to burn out your body long and short term. If you put GSP's mind in Hunt's body, the total sum wouldn't be Hunt, and who knows, he might be making a lot less money now or be less of a fan favorite, or just flat-out be a worse fighter. But somewhere between the space of an all-out work ethic and just being lazy and negligent, there's gotta be some wiggle room, I'd say in his case, a LOT of wiggle room. He's been smoking since he was 10, he was still smoking when he won the k1 grand prix at 26, and I'm pretty sure he was also smoking during his Pride stint. Not sure if he still smokes, but that's at least a period of 20 years of smoking for an athlete who's highly depended on cardio. And I think he ballooned up to over 300 pounds before his fight against Werdum, there is no way that helped him increase his chances of beating Werdum because eating shitty foods made him so happy and relaxed. I also generally don't think winging the training is better for longevity, because you will pay for it in the actual fight. There has got to be some realistic form of improvement there without compromising your base personality and happiness, if he claims otherwise he's just being dishonest imo. So I maintain my opinion he wasted a lot of potential.
