One man's logic is not necessarily another's!
The bit I wasn't so sure about was the bit where he's explaining the reason why ducking/bobbing/weaving don't work against WC. For the purpose of this thread (should it develop into a discussion) I'm going to use bobbing, but it does cover a few similar but subtly different movements.
I know WSL worked with boxing for some time, so I was kind of surprised, and then again it may be as David just said, an inadequacy in the translation. Of course, as WSL said, if you're good enough at following up, striking with different parts of the arm/hand that's out there you should be able to keep the pressure up on someone using such evasive moves. But as anyone who's boxed/sparred/fought a boxer knows, that bobbing is not the big movement that it's sometimes made out to be.
It all comes down to how good your partners are I guess, but a good boxer will slip and duck very very quickly, and just the head is enough... so the problem isn't that the good chunner can't follow up with something, but that he'll have trouble following with anything effective enough to make a difference, bearing he has to deal with redirecting his first failed strike, adjust range, hit a very quickly and erratically moving target on probably different surfaces at short range though with arms likely to be already extended etc.
Elbows are a good answer of course, but also bearing in mind that at the end of most bobs is a power punch, very often from the inside and at angles that chunners don't deal with too often, you have to make sure you're using your elbow arsenal all the time at those odd angles in sparring, to be able to drop them so easily at will and at speed.
I'm not saying WSL couldn't do it, or that the logic is necessarily faulty, but in a fight with all kinds of factors sometimes making a mockery of logic, I think this kind of point stated as irrefutable will lead to serious problems of execution for most of us humble practitioners.
I understand I may have the honour of meeting you and training with you later in the year, David... and though my boxing is a bit rusty and probably wasn't up to that much in the first place, I'm sure we can have a play with it then!
