A lot of people seem to agree with the stoppage, including and not surprisingly Dana white. I wonder what would have happened if this happened to Rousey instead.
On a technical level i can understand the argument and why its justifiable, I still feel that it was quick. I mean you fall down to the mat from a body shot, nothing strange here, and you turn your face away too to protect it until you get up again, intelligent defense if you ask me, just like putting your hand or knee on the floor to avoid knees and kicks to the head, here you put the back of your head in the way. Also do not feel that she has taken dangerous amount of damage either, it must have hurt but feeling sharp pain doesn't necessarily mean the end to a fight.
