Go on you tube and watch Trevor Bebick vs Takada....Ray Mercer also was knocked out in kick boxing .Ive seen pro boxers get dropped from kicks,very useful at times for a maximum results.Just watch high light reels of MMA fighter Mirko Cro cop as he shows his gayness ...decapitating people.
Not saying it is not effective and it is good to watch in mma but in a street fight if people start kicking it is gay.
