what if a white belt beats a black belt in Ne-waza??? does that mean that the white belt that has no/little "formal" training on the ground game better than a black belt that has tons of experience on that aspect? I mean its not the rank you have but the fighter himself that makes the difference. This applies to all martial arts and self defense. Many times people go more on rank and experience but sometimes talent and perseverance makes people win bouts that nobody thought possible for that person.
