Just because Chisora has some losses doesnt make him a worse fighter at heavy than Haye. If we give Chisora the benefit of the doubt then he was totally unfocused for Fury as hed just been let down by Wlad after the fight being rescheduled as well. The Helenius fight was a total robbery and I think with a bit more experience he would have beaten Vitali! He only had 17 fights behind him. If Haye had fought those 3 fighters, there would be at least 2 KO losses Whereas Chisora beats all Hayes heavyweight opponents and I include Wlad in that. Vitali has a better output than Wlad.
