One of the factors that makes MMA unlike any other sport is its cruelty. We’ve seen it several times in recent months. Chris Weidman’s leg break. Jacare Souza’s arm break. Jamahal Hill’s arm dislocation. Now, we witnessed Conor McGregor’s lower tibia/upper ankle fracture, putting the biggest star in the history of the sport – and perhaps the current biggest star in the sports world in general – on the skids for a while. McGregor’s comments after the end of the fight only added to the story, dragging the wife of Dustin Poirier through the mud with insults directed at her.
