There's no doubt that 'trash talking' draws in people that otherwise wouldn't pay 15 quid to watch a card. For most genuine boxing & UFC fans they couldn't care less or will dislike it.
I dislike it in both sports. Men die in boxing and serious injuries happen in MMA. It takes courage and a hell of a lot of training to get in the ring/octagon and the man you fight should know all about that and respect it.
Long term this type of crap will do both sports harm as people will see them as savage sports and outdated as the world becomes more sanitized and sensitive.
I'm interested in their character, training methods and what they can do when it matters, not hearing one call the other fella a bellend.
The only real advantage the UFC has over boxing is the relative lack of politics and the lack of shady promoters, network execs and managers ruining the sport for personal gain.
If it carries on growing these sharks will find a way to take something out of it for themselves.
I think that's what happened with Elite XC at the end of the day
So long as Dana White and the Fertittas are running the UFC, I think they'll be immune (For now at least)
