Working the body on a hurt opponent.

good question. I like good body work, but if I had to take a guess at your question, I'd say when dudes see someone about to go, I think naturally they just go for the knock out vs continue to break down the body if someone is dazed with no balance and out of it, I'd think continuing to go for the head would drop them moreso than a continued body attack. Maybe the body attack might give someone that needed time to clear their head as well. plus with going to the body, gives more opportunity to tie up, thus more time to clear one's head(assuming they can take the body shots)
