2. Jon Jones v Daniel Cormier
The fact that we were still talking about a potential heavyweight fight between these two legends of the game shows just how much of an impact the rivalry between Jon Jones and Daniel Cormier has been. The two men genuinely dislike each other. Who can forget the press conference at UFC 178, where they were literally rolling around on the floor?

Jones holds one official win over DC – a unanimous decision victory. Their second fight ended by way of head kick KO, but Jones was stripped and DC reinstated as champion after ‘Bones’ tested positive for banned substances. Even today, they still trash each other.
