I don't get why people still assume Naruto is stupid. He's not. Just because someone acts goofy and is carefree, doesn't mean he isn't talented at least in the heat of battle.
In almost every fight, he's shown resourcefulness and comes up with on-the-spot strategies to fill in the holes of his weakness. Granted his shadow clones is used in every fight, but it's the primary way he can fool and misdirect his opponents.
He's rescued Kakashi from Zabuza's water prison with his indirect knife attack.
He beat Kiba with a brilliant strategy that got Kiba to PUNCH HIS OWN DOG.
In the Forest of death, he used his shadow clones to fool the enemy Rain ninja, and got his team out of the trap where they were walking in circles.
He beat Neji by pretending to lose.
He beat Gaara initially by sticking an exploding tag in the only weak-spot of his sand-armor, his ass.
He beat Kabuto with the Rasengen, even though the Rasengen was too slow. He came up with the idea to get himself stabbed so he can keep Kabuto still.
He beat Kakuzu by attacking him with seemingly the same attack twice, except the second time Naruto predicted accurately that Kakuzu would attack the one in the back with the Rasengen, which turned out to be a shadow clone. Even the first failed attack of that fight was just to setup Kakuzu into his mistake in the second attack.
Really the only other ninja that has used as much strategic deception is Shikamaru himself.
