In a perfect world you would be 100% right.
I am ashamed to say, but if any of my mates got taken to the ground ive kicked the guy on top in the head every time. And every time its been a brutal KO before my friend got his.
The ground in a street fight is death, if you end up there try to surrender or beg anything to escape with your health or life.
