The first person I can remember getting cut for holding onto a sub was Babalu when he fought David Heath. I just don't get why people don't see the danger in what Rousimar did. Heck when you train this specific sub they tell you not to apply pressure to it. When I use to train (I wasn't that good for the record) if we got this sub when rolling the other guy would tap and then we would work on the escape in a safe manner. If anyone wants to see how dangerous this sub is (and how quickly you can go from no pain to being on a strechter) watch Mike Brown vs. Imanari it isn't pretty. People also saying that it took about one second for the hold to get broken after the ref touched him two things: first he cranked it before he let go, and two the second the ref moves to stop the fight it is over. Heck Anthony Pettis didn't need to wait for the ref when Benson verbally tapped and that was a championship fight he let go right after the tap. I hope though that Rousimar gets some help the guy has talent. P.S sorry for another thread on this.
