Yeah, that's something I talk to a lot with Bryon - just how overspecialized the teams of Konoha tend to be rather than well-balanced, or at least having those specialized teams become more balanced by having them learn other skills outside of their specialties. Otherwise, if any one of them ends up in a situation without someone being able to cover for their obvious weakness, they are taken out rather quickly because their specialty was all they had/relied on with nothing to fall back on (besides basics) and the team literally loses a third of their strength.
Like, for example, Tenten was lucky that Temari wasn't aiming to kill her in the Chunin Exams or else, had they been enemies seeking to kill each other on the battlefield, she would have been toast and Team Gai would have lost their only ranged specialist, leaving them wide open to be taken out from a distance by their enemies with no way of effectively fighting back and most likely leading to their deaths. This is what lead to Neji developing the Air Palm to give himself at least one slightly ranged attack and not solely relying on melee with the Jyuken, and Tenten learning how to actually wield some of her weapons for melee combat rather than simply throwing them all from a distance.
Or, supposedly most importantly, look at Naruto. As I keep saying, Naruto never truly won most of his battles due to battle skill or anything like that, but merely moments of stupidity at Kishi's convenience, Talk no Jutsu, or simply overwhelming opponents with brute strength via Kurama chakra and attrition with the opponent running low/out of chakra long before him, but as we see against Sasuke the first time in Part Two, once Kurama's chakra was taken out of the equation by Sasuke's Sharingan, Naruto has absolutely nothing else to fall back on besides things Sasuke and others had already seen (a bunch of times) before (only a bit bigger in the case of the Odama Rasengan) because he was never taught nor bothered trying to learn anything else besides what he already had, which was very, very little (even Sasuke at least learned to wield a sword, how to more effectively use his Sharingan, and created variants of the Chidori rather than relying solely on the Chidori itself). Even Sage Mode itself, alone, ends up quickly being made obsolete and requiring Naruto to mix in Kurama's chakra to boost his power, and even against Nagato, even with Sage Mode, Naruto still ended up technically losing until Hinata's stupidity made him unleash Kurama's chakra, causing Nagato to waste most of his own chakra on several failed jutsu while Naruto is able to conveniently be made full strength again because of Minato seal hax and Kage Bunshin Sage power, and Nagato's moment of stupidity at the very end to allow Naruto to hit him with the Rasengan.
And the fault largely falls on the senseis. In fact, almost all of Konoha's senseis of that generation, when it came to their own teams anyway, seemed pretty lackluster in one way or another.
Already talked about Kakashi.
Asuma was way too laid back, seeming content to only observe his team while simply letting them learn from their respective clans for enhancing their own kekkei genkai-based abilities rather than actually teach them much himself besides the basics (if even that).
Kurenai seemed similar with Team Eight outside of Hinata, of whom she took a much more personal interest in due to pity, and perhaps maternal instinct.
Gai was the best of the team senseis in terms of attitude at least, but let's face it, he's largely a much more physical and melee-oriented guy himself, so I doubt he could have done anything with Neji when it comes to the Jyuken and he is certainly no weapons specialist like Tenten, so all he could really do was train them more physically like he is used to doing for himself and Lee.
Jiraiya clearly never bothered trying to teach Naruto anything new, opting instead to focus entirely on having Naruto learning to unleash and control more of Kurama's chakra, but when that obviously failed, he still never bothered to try to teach Naruto anything else to make up for his deficiencies without it, which is extra stupid when you consider he was supposed to be preparing Naruto to take on S-Rank, Kage-class criminals who were, aside from being as powerful, if not more powerful than Jiraiya himself, were also hand-picked for their power, skills, and more effective anti-Biju/Jinchuriki abilities, while all were able to be controlled by a, at the time, single, mysterious individual who could only be assumed to be much stronger than even ones like Itachi and Kisame.
Even Iruka, who was usually the attempted voice of reason at times, like when he argued against Team Seven being given a C-Rank mission so soon or against having the Konoha rookies enter the Chunin Exams due to their inexperience, thus much higher risk of being hurt or even killed, and such, and you'd think would be the one to keep at least Naruto conscious of the reality of things, was willing to simply stand aside and let Naruto ditch Kurama chakra training early to go play hero in the war rather than try to get him to see that the war wasn't solely all about Naruto himself.
The only ones who seemed to take sensei duties completely seriously and got far more advanced results compared to everyone else, including Naruto, were Tsunade with Sakura (as we saw, Tsunade had no qualms about Sakura getting injured during dodge training and also helped her mature mentally and emotionally, as we saw with early Part Two before Kishi screwed it all up) and, ironically, Orochimaru with Sasuke (becoming more patient, far better control with the Curse Seal, actually using pretty effective Genjutsu rather than brute ninjutsu power, and so on) when you look at the early Part Two results.
