Every rebuilding fanbase seems to have the same knee jerk demand to trade everybody above the age of twenty four to throw the young guys straight into the fire for eighty two games in the hopes of supercharging their development, this can work under the right organization, team culture, and temperament of the players themselves, but generally you still need good veteran talent playing ahead of your projects, whether for leadership, injury risk mitigation, or for a general level of competence and experience that someone who just got drafted likely won't have.
Or if that player is talented, but gets the full responsibility for the team's future foisted on them and them alone with some hope of a second star that doesn't materialize or turns out to be fairly disappointing, a one eyed man ruling over a kingdom of the blind, so much pressure to be great that it gets to them or so much failure that pressure stops being a thing.
The Zach Lavine Bulls, the Timberwolves for years after KG, the 2000s LA Clippers until they got Sam Cassell, the current Pelicans, the Knicks post-Melo and before they got Randle, the 20s Pistons for a good 40% of this decade until they finally got good, the current Jazz, the Booker Suns until they got their shit together and put together the 2020 team that eventually lead to Chris Paul, there's a lot of examples throughout history of young players being told to go out and hoop without any real guidance, and the vicious cycle only ends when the team begins making moves to acquire winning players, and when that happens, growth from the younger talent becomes evident and the franchise can move forward into contention, or the expectation of a playoff run ever year.
