Maybe. Or maybe nage is the bad guy, and I'm grabbing his wrist because he was about to draw his sword on me. Or hit me. Sometimes good guys need to attack, too.
O.K. Agreed it seems like a banal statement, but on further inspection it brings questions.
As you say above that could also be a scenario. Have you trained like this? Have you ever had nage holding something, willing to use it, so that grabbing the wrist has more reality to it?
Thus yours is a good observation no?
