Shouldn't you do it on grass? If someone gets KO'ed (OK, small chance) they can crack their head on the pavement. When people are "accidentally" killed in brawls, it's usually because the back of their head slams into the ground when they go down. I think I read this is what caused the major damage to that Giants fan. From what I remember reading, he only took one sucker punch but the back of his head slammed the pavement.

Anyway, put me down for 320 to win 200 on MF.
