Dave - Brazilian Ju Jitsu is not the same as Japanese Ju Jitsu.

It is 100% based on 'wrestling' techniques.

I trained in Japanese Ju Jitsu and in Brazilian Ju Jitsu so i know about both.

Brazilian Ju Jitsu competitions do not compare with push hands competitions.

Its like comparing tennis with swimming.

Your posting of that example merely confirms that you are not informed about Brazilian Ju Jitsu.
