Quote from Brass:
Seriously, you don't know what you're talking about. And pavement is not smooth. Try sliding on it with some bare skin. A struggle would have cause some scraping along with the slams, even though the scraping would not be necessary to cause the scalp to bleed. You've never been in a ground fight, have you?
I have... I've pointed out before that I've trained in MMA for a pretty long time...
Scalps bleed from high velocity strikes and from "jagged edges"... Pushing down on someone probably isn't high velocity enough to make them rupture their scalp... It could however, cause bruising, swelling and a possible concussion. Anyway, without a medical report or a close up examination this is pointless.
