When you fight a wrestler with great hands, you are going to be in big trouble. As a jiu jitsu specialist you need to take the fight to the ground. They always say that you don't want to end up on the ground, but you really don't want to end up on the ground but when it goes to the ground you want to know what to do. You can still snap an arm while someone is trying to cave your head in. I've been there, and it does work. I was choking a guy out while two other guys were trying to knock me out. I held he guy until he went out, and then I moved in on to the other two guys. So I would say it's very effective. That's why most of your top mma fighters have a strong background in Jiu jitsu!
