I do not believe the practice of wrestling of itself is that important, still very imperative just slightly overrated. I think why wrestlers translate well, especially Americans because of the discipline of the weight cut. I think wrestler has the advantage of having to weight cut straight from the days of school or even collegiate level. Discipline, a wrestler, can tolerate a lot of pain. Also, a lot of wrestling is built on cardio. In wrestling, you need cardio. Also, repetition, what I see from wrestlers that they have the best concentration in the sport, they can do the same drill and keep composure for 25 mins with ease. Also, a wrestlers body is built for the wear and tear; they have a threshold for pain than most other fighters for the body overall, especially with ligaments. Also why American wrestlers dow ell. Is because from what I researched that they learn. There's three styles, three different art forms of different rule sets. Ect which different from boxing where usually you stay in yo lane. Because of Olympics or different tournaments. Wrestlers do multiple tournaments. Therefore the ability to expand into BJJ or Muay Thai is probably more natural than a kickboxer going into wrestling because they have the expertise and trained to take new info already. Obviously, I think there are pitfalls in wrestling in practical use, and wrestlers coming into MMA. Is no easy transition. Where its probably best for an athlete, to go out of high school than colleges like Dominic Cruz and Jon jones. I will try and explain my holey analysis as to the failures of wresters in a different post. But in the unites states, unlike where you concentrate your talent, it's a conveyer belt of wrestlers. So they high school, nwcaa(Tony Ferguson), Olympics(cejudo), NCAA Div 1(Jon Fitch). Ncaa div two jake shields), NCAA Div 3 (Corey Anderson), njcaa (Cain Velazquez), NAIA (Abdel Trujillo), even pro wrestling (ken shamrock. This must mean America has the largest pool of martial artists, theatrically. Maybe China with their taichi n shiz idk.
