Erik Paulson is a BJJ black belt and was a student of famous shoot wrestler, Yori Nakamura (and he a student of the legendary pro wrestler, 佐山 聡, Sayama Satoru a/k/a Tiger Mask). He was also fighting in Shooto (Japan) when Shinya Aoki was like 9 years old (don't do the math, just trust me). I guess what I'm saying is Paulson is grappling royalty and this is all super cool, old school meets new school badassery that we, as grapplers, benefit from learning (I'm sure the Dictator could have said that more artfully, but he's a real writer and I'm really just a grappler with a computer).
If you get bored for some reason during the video, be aware that there is a surprise guest grappler appearing toward the end and you don't want to miss that. I won't spoil the fun surprise, but it's Javi Vasquez.
