Yeah, but if 2x2=4 but you have 2+2 then that should be 44. So 4-22+44= 2
It's an argument for another thread, not here. The discussion that we're trying to say is that you don't need to be a bjj player or really study bjj to be successful in MMA (general breakdown).
There is a world of difference between a boxer's body punch and a kyokushin fighter's body punch. It's still a punch, and it targets the same area but the difference is in the style of the delivery. I believe they are both quite effective also, so it's not going to be the case for the weaker technique to be exposed and vanish from existence leaving only a generic 'body punch'.
Same thing for say a karate round house and a muay thai roundhouse. Totally different kicks, but both have their uses. Their essential discipline might be a 'kick to the body' but still they are distinct techniques with neither one being superior in all settings.
This applies to grappling also. A wrestler's take down may be different from a judo/sambo takedown, but they both work and are, in my opinion distinctly, different moves.
I was responding more to the notion that there are no essential styles.
However, if that wasn't the point either, then I guess I am not as smart as my mother always told me I was.
