This guy is a professional boxer and a world champion ... this guy knocks you out with one punch. You don't come close to landing and chances are ... he lets you punch first, side steps you, and then counters with a KO blow. He may also let you hit him with your hardest punch ... take it flush, show no effects, takes your heart away, and then knocks you out.
but dont do it compared to you. that's ignorance. i fought at am successfully and no matter how it looks on 'TV' don't be naaive enough to start a post like that. it just won't happen.
