I think Conor McGregor has found his niche with the trash talk and lots of fighter are now mimicking it and ithe UFC is turning into WWE outside the Octagon.
However I think there are many different characters that can have mass appeal. The UFC needs to tap into other personas. It may take a bit more marketing however it is worth it as there are many Conor McGregor type personalities around.
Agreed, because if we just focus on the loud brash talkers, we miss the quiet talented ones.
I like the WWE analogy though :-)
