when you think realistialy about the 2 of these men fighting then it doesnt take to much time to figure out that Lee would have beaten Ali, not easily, but never the less in a short amount of time. Why?

simple, because Lee had a mixed martial arts bag, and most of his attacks came from using his body, and most of the time is legs! i seen a porgrame once were lee was saying why his style was better than boxing, simply showing that his legs, have more hitting power, can be faster, but most importantly, have a longer reach than a boxers Jab

also lee can knock u off ur feet with 1 inch punching distance!

Ali would have lost, unless he was able to hit that one puch, but i dnt think he owuld have got that close!
