To be fair man, there are only a few ways somebody could kill you with their bare hands (one on one). The majority of those techniques require good body positioning and pressure in the correct area. The only way that can be achieved is with is realistic drilling and preferably sparring to. These guys do seem to be pressure testing, however, you can't pressure test how to kill somebody, so how would you know if you could kill them? (:

My assumption was that a better grappler would be able to beat me if we were grappling. Also, why does everybody assume that if I want to grapple, I pull guard?
