The difference between jiujitsu and a good majority of stand up fighting arts is the mentality.
When a jiujitsu artist goes for the submission, its the end of the fight. Even when its just playing around, making someone tap out is pretty much the equivalent of killing someone (choke) or seriously maiming them (armbar, ankle lock).
When a stand up fighter fights, its usually, “I’m going to throw these punches and kicks. They are going to either wear you down or knock you out.” The techniques when playing around are just taps and when they’re serious, both fighters are prone to injury. Kicks to elbows or knees, fists shattering.
So in the essence of just basic training, I think jiujitsu artists will always have the upper hand because when they succeed in tapping someone out, its pretty much the end of the fight no matter what. A stand up knock out, I think is alot harder to achieve.
