Right now it has to be Whyte. He looks like he may well be on the slide, but losing to Fury isn't the final nail in anyone's coffin. Since Fury got with Sugar Hill he has had 3 fights. Wilder II, Wilder III and Whyte. All three ended in a stoppage In contrast, as much as I like Zhang, Hrgovic has been his best performance, and in that fight Hrgovic looked terrible. So I don't see how either can be ranked above Whyte.
