"Hey, this video cuts off that sweet technique just when it's getting interesting, this sucks! Fuck this -- oh wait, I love this song." Eddie Bravo: the Sesame Street of jiu jitsu.
sadly this is widely true and i train bjj myself. even top level jiu jitsu guys that fight mma dont have much success. but ofcourse i believe bjj is the best and most universal self defense martial art.
