Thats the point, people have actually won over Tyson. Therefore there are a number of boxers that hit as hard as him. And you cant go thinking that Tyson Could kill a cow because his tyson, it's because of his training as a boxer that he was able to kill a cow. Now i'm not insinuating that all boxers punch that hard, but close (depending on their weight ofcourse). Because that is what is taught and trained in boxing, hitting with precision, power and speed. And to get back to the main point, street fighting, thats all that is needed in winning a streetfight. Now, the one that hits (with precision, power and speed), can evade punches and keep a distance AND can charge in a controlled fashion with speed, he will most probably have the best prerequisite to win. Now that is exactly what is taught in boxing, thats about the only thing that is taught in boxing. And it's taught good, real good.
