Then again, Sakura's contribution to the story is pretty much as a trigger, not as a person.

After the chuunin exams and her supposed revelation that she has to work to be a ninja, she's back to her old self - sitting on her butt, worrying about others. So what did she learn, really?

She hasn't grown. If she does, then great. Otherwise, she's a waste of time.

As for the topic: I think a couple of them might. I'd have thought Neji, considering what he saw, realises that Naruto is special; maybe Shika, too, although he probably can't help but see Naruto as an idiot (he was all through the acadamy, after all).
