True to his word, Conor McGregor brought complete performance

What could be the appeal of something and someone so bombastic?
McGregor, in particular, has been viewed sceptically as a triumph of style over substance; after all, would the UFC have fast-tracked anyone else quite as blatantly, if they weren’t so glad to have an English speaker who could mix Irish
with the best (or worst) US west-coast hip-hop brash and trash talk and shift from one mode to the other in an instant, depending on the circumstance and chat show?
