can't be one-sided in MMA...If you can only operate on the ground you'll get put up against someone who's known fr stuffing takedowns. Look at Chuck Liddell....he has very mediocre ground game so everyone tries to take him down instead of standing up with him.....it doesn't work well. I've only seen Chuck taken down once.
I took 13 years of ishin ryu karate only to find it doesn't help worth a crap in a MMA fight. Recently I've been working lightly with a grecco coach. I'm not looking to compete or anything, just like to brush up on some usefull skills.
