To win a fight you only need one weapon, true. but consider this.
Kick a Boxer: Longer range and reach, more powerful strikes
Box a Kicker: Wait for an opening and shoot insided rendering legs useless. Faster techniques and generally more precise.
Kickbox a grappler: wait for the lunge, spring backwards or sideways, striking with feet or fists.
grapple a kickboxer: wait for an opening, or learn to make an opening, get in close bind the legs and arms from moving, for these are his best assets go to ground and mount, or stay on feet, there are different schools of thought for this, as many of you know.
I am not in any way saying that boxers are not proficient fighters, Im sure there are many boxers out there that can clean my clock, but that wasn’t my point. My point is that MA, CMA especially, train in all the above aspects, and more, such as force absorbtion and redirection(which is just physics..energy can’t be destroyed, only redirected. When you punch a guy and he performs a strong block, he is absorbing the blow through his arm, and consequently into his body. Some train to deflect and pluck in addition to blocking. Which is to flow your arm around the opponents and pull it to your center using the waist as a tourniquet. The force of the opponents punch then works against him as you can work him into throws, joint locks, or just issue a strike of your own using the opponents power.) Also, some train to begin a strike in the feet, bring the power to the legs, up through the waist, into the stomache, through the chest , into the arm, and finally into the fist. This, essentially, makes punching an act of the entire body rather than a movement of the shoulders, or even the waist. Now I have seen some boxers do this, but most do not, they have a static stance, especially the heavyweights. So yes, you only need one weapon to win. But chances are, one with a bigger arsenal will have what it takes to neutralize a boxer of the same skill and athleticism.
Oh and Ap. In the future, please do not discount my opinions or experiences without providing some sort of intellectual feedback…
