I dont know what you are talking about to be honest. We get college wrestlers all the time, and yes they are way, way way better grapplers than the standard white belt that walks in, but they are just as clueless as anyone when their arm gets trapped or when they are on their backs.
Generally speaking, I avoid pulling guard with them, and focus on submissions and taking the back. They do have explosiveness that others lack though, thats for sure. We have this high level college wrestler who is a blue belt and the guy can explode out of the worst positions, the thing is though, we all know his tell tale signs when he is gearing up for it, and brace accordingly.
I dont understand this fetishizing of wrestling to be honest. Its a wonderful skill to have, but hardly better than BJJ by any means.
