Let me preface by saying that I’ve studied Jujitsu a few times (less than a year total) and I’m a big believer in its power in certain circumstances. I think these days we should all at least have some takedown defense and some skills in the guard (like how to get up).
But the reason I study Wing Chun is because I think the most likely streetfight scenario will involve standup striking. This is where I decided to specialize. Once I decided this, I did some searching until I landed on Wing Chun, then I did some lengthy searching until I found a school that could teach me how to use Wing Chun in a streetfight with the sort of attacks I’m likely to see out there in the real world.
One of the other reasons I chose WIng Chun, instead of, say, boxing or Muay Thai, is that I want to study a technology that isn’t also going to damage my health. I understand I’m sacrificing a level of reality here. I believe that the closer you get to actually fighting in your training, the more prepared you’ll be. It only makes sense. This is why Bruce Lee called some forms of martial arts training “swimming on dry land.” But, I think its best to weight the pros and cons of these things in a mature and sensible way. What are the odds I’m going to be in a fight? What is the level of skill I’m likely to encounter?
The developers of Wing Chun devised a very clever methodology to get you as close to real fighting as possible while developing your reflexes (which they also realized was of the utmost importance), called Chi Sau or Gwoh Sau. We have some newer technologies which might help us train other corners of this skill (reactive striking with full power to help develop the correct stimulus-response loop).
As we’ve seen in the UFC and other mixed martial arts sports, as the fighters evolve, the most dominant have the best mix of physical capabilities (endurance, strength, reflexes, ability to withstand strikes) and skills (striking, takedown defense, grappling). Those of us who are amateurs have to do the equation (how much time and money do I have) and come up with their individual answer (what should I study in that time to get me closest to my goal, minus the time I need to spend to be strong and to have cardio capacity).
Some BJJ people (and I often think many if not most of the commentators are armchair BJJ people who don’t train) are so into their art that they have this mindset that its the ultimate and can beat anything. I think its true that in the UFC, if you don’t have a well-developed ground game (BJJ or outstanding Greco-Roman or something similar), you don’t stand a chance. Just look at Connor Macgregor’s last fight.
But out on the street, you may find you want to make sure your striking game is developed. Here we are have two knowledgeable guys making this point with a lot more experience behind their conclusions than I bring. I think Rogan is a Brown Belt in BJJ (and of course, is the main “color” guy for announcing UFC fights) and Eddie Bravo is a Black Belt in BJJ who has beaten Royler Gracie in competetion.
