I think you are being too simplistic with the topic.
Guys like Manhoef or Hendricks can knock guys out even when off balance or not that accurate. They just have horrific power they generate.
A guy like Mac Danzig above, needs the perfect storm of his best shot, landing in the best place while his opponent is most vulnerable, to get that KO. BJ Penn beat on Joe Daddy far worse and far longer and seemed to land harder shots and yet could not get that KO.
As you say truly skilled fighters and martial artists understand this. They understand that accuracy and timing can be even more valuable then raw power and that even a guy like Mac Danzig can become a KO machine if only he had the skill to get that timing and placement down every time.
Anderson is one of the rare few who can put it together so well in MMA. No insult in acknowledging that.
