I think what spooky is trying to say is that the punches work for us, and they work better for us than other punches do. Its the same way around. I dont see why a taijutsu punch would be of any advantage to a boxer. Are they gonna use a boshiken tsuki to unbalance their uke, use ganseki nage, tobiori over the ropes and run away? (for not ninjer speakers: Are they gonna use an extended thumb strike (kinda hard with gloves on, eh?) to unbalance their opponent, grab them in an under arm-type throw, dive roll over the ropes and run away?) Probably not. In fact, not at all. Our purpose isnt to sit there and fight, its to break something and/or leave. So why would a boxer want to do this, when they are so damn good at beating the crap out of each other?
