I said from the beginning how I'd seen boxers over the years who's kayo ratio would drop dramatically once they started figting good fighters, sometimes to the point where they started to become known as average or not really special punchers. I said that in regards to Wilder but I've seen guys who were kayoing everyone they were fighting until they fought good fighters. Ever hear of Milton McCrory? was kayoing everyone until he started fighting good fighters, Tyson was kayoing everyone in the first round until he fought Jesse Ferguson who was never much more than a journeyman, and then he went to a decision, almost losing against Quick. The class of fighter matters, and the class of fighters around hasn't been very good for a long time.
