Not sure what the "slow???" is about.
That BJJ and Judo share the same core subs is quite obvious BUT to suggest that the typical judoka is at the same submission level as a typical BJJ player is incorrect.
When was the last time a Judoka won a submission grappling tournament?
The elite submission grapplers compete in the Abu Dhabi and they all have BJJ back ground.
It is not a slight on Judo, heck I am a Judo Shodan remember?
It just is what it is and the simple fact is in BJJ it is submission FIRST and throw second and in Judo it is the reverse.
Typically.
It should be noted that this IS changing so...
