Talking the talk but not walking the walk would be a fitting name for the graveyard where the careers of MMA fighters go to die once they’ve run their mouths off and then got beaten. Indeed, the industry is full of pretenders who think they have what it takes to succeed in the octagon, only to be brutally found out.
To be quite fair, this isn’t a feature exclusive to just MMA. All combat sports, to some degree or another, are awash with loud characters who do more outside the ring than they are able to do in it.
