I agree with this. Excepting the highly trained grapplers (who are an unlikely assailant), most grapplers wouldn't be able to get me to the ground (at least not all the way) to test my ground fighting ability. My primary work makes me harder to take down that I used to be, so that is my first (and best) defense. The ground work I practice isn't so much in case I get attacked by a grappler, but in case I get blind-sided and am on the ground before I know it, or I step on something and fall down. I rarely practice and never teach things like that BJJ arm-bar escape, because that kind of complex move is highly unlikely within the context of an attack. It's similar to my decision not to practice defenses against those KO diving kicks the Kyukoshin (did I even spell that right?) folks do.First of all, I HAVE grappled. Second, I have enough knowledge to know what does and does not work on the ground even if I don't grapple on a regular basis. My suggestions were more about what to do to prevent things before it even gets to the ground. The best way to handle being on the ground is to not get there. Some people ask, "How would WC defend against an arm bar?" And I say, "Don't let the guy get you in one!" Because once it is locked in, then it's a very tough spot.
