Well Kakashi is a genius but it still surprising Naruto didn't learned anything with Jiraiya.

And other thing that suprises me is that Nine-tailes is actualy weakens Naruto's chakra. So that what Nine-tailes meant when he told to open seal to become even stronger. But how much does Naruto realy has chakra if Yamato suppress Kuuby and Naruto will have 100 times more then Kakashi but Yamato isn't First so he isn't able to suppress (i would say half of it and i betting even First wouldn't be able to suppress entire Kuuby's chakra.
Here just a theory but isn't container should be equal or greater to content that is inside of it?
So how much Naruto has his own chakra to that would still be 2 time more then Kakashi?
