No catch wrestler has ever won ADCC, the number of non-BJJ guys who have ever won ADCC is an extremely tiny handful of like less than a dozen guys. Curran Jacobs, the guy who won the "catch wrestling world title" after beating a bunch of Josh Barnett boys in a tournament got absolutely humiliated beaten 2:0 in less than a minute by a random BJJ blackbelt and left with broken bones. All of Gotchs boys got rekt in real fighting, beginning way back with Ken Shamrock getting submitted by Royce Gracie at the first UFC, meanwhile BJJ dominates the grappling world. That includes Sakuraba who has gotten BTFOd so many times in MMA fights that he basically has brain damage now. Catch wrestling is basically a number of techniques which are illegal in free style wrestling that old timey wrestlers used to either defend themselves or fuck up other wrestlers who weren't suspecting it. It borrows most of its submissions and techniques from Judo and Jiu Jitsu. It's not a real martial art which is why you can't learn it anywhere except from a couple instruction videos peddled by salesmen like Josh Barnett or Jake Shannon and the occasional McDojo, and all it takes to be a great "catch wrestler" is "be a great freestyle wrestler and then learn a couple basic submissions", so if you don't have a freestyle background already catch wrestling is basically useless (and Karl Gotch wouldn't train you anyways). If you believe anything this grandpa who hasn't fought a real fight since his wrestling olympics days says you're just hopeless.
