My personal view is that Kevin Lee had the highest set of skills. His downfall is chin and gas tank. Tony is diverse but can be held down(castillo). His striking is very good and his gas tank is his biggest asset Conor has a good left hand but gas tank is usually half full. Khabib will beat Fergusen and conor but will lose to Lee Conor beats ferg and lee None hold the belt for more than one title defense!!
