I don't think that word means what you think it means...
Not really, since I personally don't use a Ashi Barai for takedowns, and I've personally never encountered it as a Bjj takedown. I admit it was cool to see it being used as a takedown during a Bjj match.
That said, I am interested in seeing what else you can produce.
As I said before, sacrifice throws can be done without tori grips, grabs or grapples by any other name....
Sumi gaeshi and uki waza are able to make use of a defensive stance or modified jigotai which has no grip on the uke's judo gi.
If your uke has a solid grip on you, you can throw em.
Bear in mind, that according to the IJF Referee Commission.
They say that when a throw is successfully executed, resulting in a nice, clean throw onto Uke's back, it is Ippon even if Tori does not have a grip.
This ruling should tell you something. Its legal to throw without grips.... what is the case on the street.
If a guy really wants to hang onto me... I will take him for a mean ride. If I was a bjj man like you... drop right down into sumi gaeshi... into top mount
Now for the record, I have given you four judo techniques that violate your assertion that you HAVE to grab to throw, or takedown.
I am not your personal researcher. I have been a good sport, and shared multiple or various ways a judoka player can do it.
You can find more no_grip judo techniques. I have... and tested such.
