Meso, boxing requires exceling in one skill...boxing.
MMA requires being competent in several martial arts including BJJ, boxing, wrestling, muay Thai, etc. and exceling in at lease one of those...usually BJJ or wrestling.
Today's MMA competitors are highly skilled and extemely well conditioned athletes.
I do for once agree with this clutz, the UFC is a million times more skilled than it was in the mid 90s
