The "Sport" may have evolved but the fighters have not. Think about this, Usman was saved from Covington after taking a kick to the stomach and pretending it was a low blow...in the original UFC, Usman would have been fucked because low blows were allowed but the "evolution" of the sport saved his ass. Look at every weight class below HW... All of those guys would have to be facing Miocic, Ngannou and Lewis but the "evolution of the sport" allows them to cut weight and duck bigger competition while giving them the opportunity to boast about being "champions" in irrelevant divisions. Makes for great ratings but we TRUE FIGHT FANS know that these belts are just a "pat on the head for the little guys".
A TRUE evolution of MMA would mean that fighters could face competion of any size and rank and still survive.
