IMHO, wrestling (all styles) is great stuff, but the difference I see vs Judo (standing) and BJJ (on the ground) is that while technique is important in wrestling, it is also very dependent on physical strength. Judo and BJJ do more to teach weaker people how to defeat stronger people.
This is a common misconception. Judo, BJJ, and wrestling all depend equally on technique and athletic attributes like strength, speed and endurance. Technique is a multiplier - you can conceptualize it through the equation E = T x A. (Effectiveness = Technique x Athleticism). This is equally true in wrestling, Judo, and BJJ. (I'm simplifying of course. I'm leaving out mental attributes and all the different kinds of technique and athleticism.)
The difference is more a matter of the culture and the typical practitioners of each art.
Most wrestlers start out training as a sport in middle school or high school. This means:
- They are preparing for competition in a short period of time, perhaps only weeks from when they begin training.
- They are athletes, and there is status rather than stigma attached to winning through superior attributes.
- They are young and many of them won't have the attention span to focus on lessons regarding subtle details of technique.
- They are young and have the recovery capacity to handle lots of physically intense training sessions.
Given all this, it makes sense to start young wrestlers out with some technical fundamentals and then turn them into athletic beasts with a lot of intense physical conditioning. That physical conditioning will develop and pay off quicker than focusing on fine technical nuances.
However wrestlers who stick with the sport long term and who reach a high level of competition will end up developing a high degree of technical expertise. A D1 college wrestler may be in fantastic shape, but so are all his opponents. After a certain point, an athlete reaches the limit of their athletic potential, but they can continue developing their technique indefinitely.
In contrast, when you look at BJJ:
- Most BJJ students are adults and may not have the physical recovery capability to train 3 hours a day 5 days a week.
- Most BJJ students don't compete in tournaments and of those who do, only a minority do so on a regular basis.
- BJJ has been marketed since its inception as an art where "a smaller person can defeat a bigger, stronger opponent", thus the motivation for the instructor is to show how that can be done with technique rather than through superior attributes.
However BJJ practitioners who want to compete at a high level are going up against other competitors who know all the same technique they do - so they end up devoting serious time to developing their athleticism. The top BJJ champions are generally super-ripped athletes.
So, culturally wrestling and BJJ approach the mountain from different sides, but once they get to the top they are the same blend of high-level technique and athleticism. (I think Judo can fall closer to BJJ or to wrestling or in the middle depending on when and where you learn it.)
Speaking for myself, I'm a 58 year old with a desk job. My value of A in E = T x A is pretty low. But I continue to improve my technique. And possibly the single biggest area of growth in my BJJ over the last few years has been in my wrestling. There are a lot of subtleties in wrestling that make things work easier for me as an older practitioner.
