There is alot of talk going about about the ineffectiveness of head and upper body movement in fighting styles permitting kicks (and take downs). While there is a certain logic to that statement I find it hard to believe. Are these techniques really ineffective in MMA (or in a street fight)? Mind you, I expect that there must be some modifications to make it applicable. And yes I have seen the Couture vs. Sylvia match, regardless, it is still rarely utilized.
