You are underestimating Naruto's ability to control chakra. Early on in the series, this would be true. It had been emphasized many times early on throughout the series that Naruto was terrible at controlling his chakra. However, his time spent with Jiraiya has served him well. Naruto is no longer the control gimp that he used to be, he may even be one of the more adept at controlling his chakra now. The ability to use Rasengan is proof of that. The entire technique is dependant on mastering the control of ones chakra. Its why Jiraiya spent so much time trying to teach Naruto to control his chakra better.Originally posted by: Hotsuma
I don't thinK Naruto's chakra molding is as good as Sasuke's. The large amount of chakra and stamina complements Naruto's sloppy style. If he had the same amount of chakra as another gennin, he'd probably be a piss-poor fighter.
Also, as far as Kakashi using the kage bunshin... If you remember correctly, he used it as a bluff. He was able to create them, but he didn't have the chakra for them to be effective. He was hoping that just the sight of them would scare off Gato's men. And Sasuke is not at Kakashi's level.
Besides, I would hope that Naruto would not be dumb enough to use kage bunshin against Sasuke anyway. One thing Naruto has always excelled at is creating effective combat strategies. Even if he came up with a very creative way to use kage bunshin, he would still know that it would not work because Sasuke would see through it with the Sharingan.
IMO, there is only two reasons that Kishimoto would have Naruto use kage bunshin. 1) Just for the sole purpose of Sasuke copying it with Sharingan. or 2) To display the power of fully developed sharingan by seeing through the kage bunshin. Personally, I would not like to see either because both ways make Naruto looks stupid in battle, which he is not.
