I totally agree. They underestimate naruto all the time.
Naruto's development is now on track, he is now training in art's that only people with enormous chakra levels (that natural, the 9-tails did not give him this) i think naruto's next teacher will be from the fox's or even the 9-tails himself
naruto is very young he is just beginning to understand himself and how to control his power and his powers-(9-tails)
naruto had a delayed start in his development so he looked like a punk in most early fights and was saved by the 9-tails-(naruto's spirit is making the 9-tails respect him and his enormous chakra contains the fox)
i naruto will be a well-balanced ninja- in early fights he always charged in with no strategy an get hit, but that was because of training gaps. Naruto will soon have long- mid- and short range attacks
i have been thinking as well, the power that itachi gave naruto was the ability to be immune to genjutsu, which is key to defeating the sharingan
naruto is also on the same track in learning and teaching as the fourth and j-man
