In the forum me an Vankuen came from this discussion was brought up and one of posters who did moy yat wing chun mentioned that he could easily take down everyone in the class from the trapping range and he noted he wasnt even a very good grappler at all. So what does that tell you?
For one your partner has to give you a bridge for you to even do that and how many non wing chun people are going to enage in trapping? He wont have to disengage his hands because he wont give them to you in the first place.
Two the majority of people who do trapping dont work directly with the clinch,throws and takedowns. If one gets passed theur arms then they will be easily take down and controlled
It tells me Moy Yat isn't good for defending takedowns?
If your opponent is shooting from outside trapping range, the wing chun isn't going to do much good. That's why I said they are next to impossible to take down once you've touched hands.
Once you touch hands it's difficult to get any sort of grip or underhook because the wing chun guy is more than likely going to react before you get there, and any holes you create trying to get your hands away are more than likely getting filled with centerline punches to the face, or, at the very least, a frame, or their own underhook.
Yes, the VAST majority of people trainin Wing Chun have little to no interest in practical application in an MMA setting. We train Wing Chun with our MMA in Wu Trin Do, but I've only seen a handful of videos covering practical Wing Chun out there. Traditionally Wing Chun is far too limited, and some of the best tools for trapping aren't even included i.e. elbows, knees, headbuts, vertical backfists, grappling.
The point is, there are some valuable tools in Wing Chun that could be used to great effect in MMA, but it takes a great deal of dedication to develop them. And more than likely any school teaching them isn't too interested in practical MMA application.
I agree Chi sau can prevent your opponent from grabbing you but if it was unstopable then everyone would train it and MMA would be over run with chi sao practicioners rather than wrestlers.....
Shooting through chain punches is like shooting through any other punches as we all see in MMA when a dude is throwing hands even hitting the other dude then he shoots in. I'm not saying the guy couldn't get knocked out and I'm sure we have all seen this shake out both ways in MMA
THe guy doesn't have to disengage, if they are trapped say one hand over the other you will hit them yes but that doesn't mean they can't drop their level and slide their hands around for a single or double.
If not how about off a lap sau from sticky hands if one gets laped (pulling arm) and thrown a little off ballance then once could go to a take down etc.?????
The neat thing about vertical punching from the centerline is that even if your opponent is unaffected, it still acts as a physical frame between him and you. You can't close distance to tie up a bodylock or drop levels if there is a fist and forearm between your head and your opponent's body.
And trying to drop levels and shoot for a single or double sounds intuitively simple right? But the Wing Chun guy can feel your hands try to slip and can sense your bodyweight drop. On a good day I simply get stuffed when I try this type of move, on a bad day I run into punches or knees.
Now like you say, getting your opponent off balance is a great way to create an opening for a takedown. When I spar with guys who aren't as good I usually try to pull them into a clinch to create a takedown opportunity, or bounce them off to create space to change levels, or redirect them to get an outside lane to get to the back.
