For decades. It’s amazing to see the evolution of the game. From Chuck to Rua to machida and then Jon Jones took over and big brothered everybody. Silva to weak ass weidman to rockhold and now Adesanya, Romero and Costa Also I don’t like that champs retire with the belt. Khabib and triple C need to come back and fight until they pass the belt to a younger better stronger faster opponent. Why not stay int the game and get kod 5 in a row like chuck did???
