Cain cannot stay healthy enough to fight in the USADA era. He's a non factor at this point. DC may be fighting at LHW, but he's actually very skilled and performs great at HW. Do you forget that he was the Strikeforce HW champ that he won via a tournament against some very tough HW? He also has HW wins in the UFC over Frank Mir and Roy Nelson. I think people will be shocked at what level DC will compete with Miocic. He will do much better than Ngannou, and he CAN win that fight. The only reason DC dropped to LHW was to avoid fighting Cain.
