Helio could fight to a draw in this way. If he used this tactics, it would be difficult for Yamaguchi to make Helio surrender.
A lot of the really old school Judoka (60 plus yrs of age guys) have low opinions of BJJ because they feel the BJJers gave up on Tachi-waza. The typical response in class to "what should we do if we have fight a BJJer?" was "slam them on their head".
