Re: So I took a Judo class today...
Yea but Judo's "take it to the ground strategy" involves puttting the attacker on the ground forcefully while remaining standing. Newaza can be used to follow up if applicable but that would be stupid if there were multiple attackers.
What happens to someone who does not train any newaza at all when they find themselves on the ground, multiple attakers or not? They are then in serious trouble. Somoene skilled in newaza is better able to get to their feet quick, whether it be escaping a pin, dislocating arms, moving to a better psotion to stand etc.
