I've noticed that the Jonin who led the original generation aren't shown to have another team after their original team grows up. Is it typical for a Jonin to only ever have one team in their career. Is it something that all Jonin have to do at some point, lead a Genin team until they all become Jonin or split up for some other reason?

For instance, Minato was a team leader, but only known to be so for Kakashi, Rin and Obito. Jiraiya had Minato and his teammates. But officially only them (technically he taught Nagato, Konan and Yahiko also), the future Third Hokage taught Jiraiya, Tsunade and Orochimaru.

It seems like all the teachers were only teachers for a single team and then moved on to do something else, whether they became Hokage, became an independent ninja as in the case of Jiraiya or whatever. It seems odd that a village would have an unsustainable system like that in place.

It just doesn't seem like there are enough Jonin and people becoming Jonin to continue a system like that. Even in the Chunin Exam, Shikamaru was the only one who advanced. If the Jonin Exams are similar in that regard, then how many Chunin go on to become Jonin in order to have a replaceable pool of Jonin to lead the Genin teams?
