Yes, I understand what your argument is. And although you are right that chisora looked a lot better in later fights, I dont think that it justifies him being ranked higher than someone he recently lost to, especially as the main reason for that was his weight loss. If he performed the same as he did weighing 260 I dont think you would be saying the same.
Have you managed to see much of Dillian whyte? he looks to have the physical attributes, put with very poor technique, wild swinging inaccurate rights. I've been impressed by cornish though
