He doesn't accept those flaws, or any flaws. He's convinced himself that he's the best when he' not. If you're the best and you lose, it MUST be someone else's fault because you're the best. Unfortunately from the very early days he was surrounded by people telling him he was the best. When he was fighting Willy Limond and Michael Gomez he had a touch of humility about him and after every fight said "I'm young, I've still got a lot to learn but it's going well". Now he seems to think he has nothing to learn and he's the greatest. The lack of humility and introspection is going to be his undoing I think. He keeps talking about stepping up and fighting Mayweather but the reality is he's nowhere near the same league as Mayweather yet. And unless he starts accepting his faults and working on them he never will be.
