Funny thread. 
Really though, it could spark some interesting conversation if you let it…
Personally, I would strongly agree with the foundational animal comparison underlying the quote. Although, to begin with, we’ve really got to define some terms which are thrown around all too loosely. It’s impossible to discuss when no one agrees on basic definitions. For instance, what is grappling, and what is striking? People alternately use the word grappling to describe groundfighting, any submission/grasping/breaking technique, any technique at body contact range, or a range of techniques including throwing and sweeps. These are all pretty different.
For instance, I consider grappling to mean submission (or submission brought to it’s extreme - choking, breaking, etc). For that reason, I would call myself a striker. However, the basis of my technique is to invade someone’s space, and control them so their posture and balance are broken. So maybe I’m a grappler? But I don’t use any submissions…
So far as the original animal example goes - I’ve never understood how anyone can consider ‘striking’ (in it’s most limited definition - that being, maintaining distance to strike then retract; repeat) a viable combat strategy against anyone, except perhaps someone who you absolutely dwarfed in skill and attributes. From my point of view, if you want to defeat someone (or even prevent being defeated yourself) you HAVE to get in there and break their posture, that’s how you win. And that’s what these predators are doing. Although I agree with the original author’s premises, I disagree with his argument. What these predators are doing bears (pun intended
) absolutely no resemblance to, for instance, BJJ’s strategy. Again, the confusion arises due to the neglect of properly defining our terms - ‘grappling.’ These predators are NOT going for submissions. These predators are NOT bringing something to the ground (except when it’s allready defeated and it’s time to eat). What they ARE doing is establishing dominant position, breaking their opponents posture, then aggresively attacking with their strongest weapon. So long as we’re going to make this argument, this strategy is resembles much more strongly that advocated by say, baguazhang or silat than BJJ. Yes, it’s true that you often see BJJ proponents advocating the ‘ground and pound’, which is more similar to what the animals are doing. However, I’m under the impression that in many cases this is contrary to the original principles of BJJ or grappling, and more an artifact of vale tudo - for example, I can think of several examples of someone ground and pounding from within their opponent’s closed guard - surely not the approach advocated by BJJ, nor that which it’s training addresses. Although, I will glady stand corrected, since my experience in the matter is quite limited.
