Interesting video here, where No Hold Barred Legend, Eric Paulson fights Sean McCulley. In this fight no gloves are worn, hair grabbing, spiked elbows, grabbing the shorts, and cage are allowed. The only thing not allowed is submissions. So, the have to beat the crap out of each other. The good thing about studying this clip is that you see all of the striking weapons (fists, feet, elbows, knee, and head butts) applied. You will see bone on bone at it's best. Please review for your study.
