I would say that too but people will bring up that it was only used in a filler. Besides it wouldn't really work on Temari's futton jutsu if you think about it. That technique is more for blocking physical projectiles or attacks, while wind is could blow through it I guess. It could stop the cutting affects I guess but I'm not sure.Hinata does have a defense. Protective eight trigrams sixty four palms.
I believe that as well.i think people underrate hinata a little, she i strong and skilled, she should be able to figuring something to win... Temari is very impatient and of course she has the advantage, but its possible for hinata to win.
