I dont get it?

the gracie jujitsu is basically more about the ground than the japanese game is. the japanese jujitsu sensei will teach throat and groin strikes aswell as parrying away punches and doing wristlocks and stuff. i take a hybrid japanese version. it mixesjudo/aikido/jujitsu and some strikes but very little. the japanese jujitsu versions do teach the ground game but the are way less focused than the gracie version which is a disadvantage in mma
