I'm not 100% with you on this one (and I tend to be more in agreement than in disagreement with your words).

I agree that uke shouldn't be trying to fall over. But I do appreciate the training methodology of level appropriate progressive resistance. (Shutting someone with nothing completely down isn't super helpful.)

I'm sure we also agree that it is best to to always be uke (that is to receive the partner). However, where we differ is that when I'm attacking and I get overwhelmed by a superiorly structured/intentioned nage such that I cannot receive enough of them without my structure blowing apart I just try to fall in the safest way I can - be it straight spine or curved.

Lastly, if I'm thrown to the ground, I might not look to stand back up - I might look to defend getting mounted from that position/angle - even if nage has no idea how to do it.
