BJJ is my primary focus these days,but from my perspective grappling is grappling. Different arts focus on different aspects of the whole based on the context they are training for, but to me they are just different facets of the same enormous beautiful gem. I have trained with practitioners of Wrestling, Judo, Sambo, Tai Chi, Danzan Ryu, Bujinkan Budo Taijutsu, Kali, JKD, Muay Thai, Aikido, Jukado, Toshindo, Systema, MMA, Karate, and more, and learned from all of them. (I've also spent time studying video of other grappling arts that I haven't had the chance to study in person.) If something works, it works. I have no problem giving credit to other styles even when they are focusing on a different aspect of grappling than I am. I am saying that, based on my experience grappling hundreds of people with a huge variety of body types, experience and styles, the stuff Steve is showing in this video is barely one step above "pummel the other guys fist with your nose."
