Ronda was never out cold though she got her bell rung several times. She was dazed for a few seconds after the kick and hitting the canvas but none of those punches while she was down connected cleanly. Her main injury today is still her pride.
But that doesn't change the fact that serious injury or death is always a possibility, even with the referee standing right there to stop it. Still the public has an insatiable appetite for this and the demand isn't going away. Boxing, wrestling, judo, karate, etc. weren't enough. They wanted MMA. We're more likely to see something even worse than we are to see it banned because it's too dangerous.
I think the best safety measure is making sure both fighters are evenly matched but it's a fine line. Dana White and his promoters want to see a butt kicking but not a big injury. I guess they are drooling at the thought of a rematch.
This is exactly the kind of thinking that is dangerous. "Getting your bell rung" is a concussion. I watched the replay to see what you guys are talking about. She was concussed.
