McGregor has been used to being considered the best talker in the UFC for the last couple years. That a;; changes at UFC 203 when CM Punk debuts as a UFC fighter. Punk has cut more promos than Mcgregor ever will, and better quality promos at that. The fact of the matter is, Punk is much more elegant and creative. Mcgregor does a decent job but if he couldn;t use curse words he would be utterly lost with a microphone in his hand. Punk can do just as well with or without using profanity. He's capable of using it but he has never used it as a crutch.
