Most of the submissions you see today in UFC were invented by Dan Severn, who was a world class wrestler, but not a BJJ guy. Because he invented all the chokes and locks with the palm to palm grip, no one was ever doing it like that before, they were all using the hand on the bicep for the chokes. A lot of fighters nowadays use the palm to palm grip when choking and it all comes from Severn, not Royce or any other BJJ person. It was unheard of until Severn came in. He used to train with Gable and he used it all over the world before MMA in his thousands of wrestling matches in Russia and Turkey and Bulgaria etc etc.
I've seen this Jones guy use palm to palm for a choke before, and thats hilarious to me, that is not from BJJ, its from Dan Severn. He wouldn't have a clue about it though
