Naruto wasn't lazy and he was only a prankster to try and get noticed. Even after the Iruka thing he wasn't really skilled either. Sasuke was always more skilled and could use his chakra better than Naruto it is just Naruto has more chakra so he's more powerful if he taps into Kyuubi but without it he's weaker than Sasuke. Makes me rethink about Kiba's strength since he lost to Naruto who had hardly any chakra control since Orochimaru did that seal. Though by then he had improved a whole lot in a short time sure but he had even worse chakra control and he still had enough to do shadow clones, transformation, able to keep fighting after being beat on alot, and koed Kiba in just a few hits.
