Sparring is like a cat and mouse game a real fight is full blown all rage, no time to think just react. How many street fights have you been in when you both get in a fighting stance? I bet not many most of the time there is yelling then the fist start flying. When ever i have done sparring they all turn into the same thing a kick fest. Ever move has its time and place where they belong. How are you going to preform rising knee in a sparring match? or the dagger? The moves you can do while sparring arent the same as what would might do while someone is giving you one of those all or nothing punches. I never said it was too deadly to sparr, im not the one getting hit in the neck.
