Karate use to be the thing when they didn't know they could be tackled and ground and pound. Back in 1979 college wrestler told me about a fight he had with a black belt in karate. He said the karate guy kicked him in the face. Then he took him down with a single leg take down and beat the shit out of him. I knew back then if you are just a striker you are in for a world of hurt without ground fighting skills.
