I don't think MMA is safer than boxing (as I explained in a sibling comment), but this aspect is interesting. Yes, MMA fighters often get subsequent hits. Which is bad. But, in boxing, when you get knocked down but not out, you get a standing count. Then you take more punishment. But if that was an MMA fight, there's a good chance the downed fighter would be pounced on, and the fight quickly ended. Both are bad, but it's hard to say which is worse.
