Patience is key. PGs take time to develop. His age, size and lack of experience dictate as much. Also...the rigors of the position in general:
The RingerA team that drafts a point guard high has to believe they will turn into an elite player. If their ceiling is only a good starter, there’s no reason to bother with all the development necessary to get them there. The key is to not spend picks/time on players who will hinder their teammates’ development...There are only a handful of point guards in the NBA who are true difference-makers, and it’s one of the hardest positions to predict since so much of the development necessary is mental.
A lottery team drafts Collin Sexton or Trae Young and they could be waiting for years for them to pay off, if they ever do.
Few point guards enter the NBA ready for the responsibility of running an offense. The position is incredibly demanding, both mentally and physically. Not only are they facing some of the best athletes in the world on a nightly basis, but they also have to make hundreds of split-second decisions over the course of a game. Even the best players need years of trial and error, especially in an era when most leave school early.
It takes All-NBA point guards an average of five seasons in the league to make the team.
Getting to that point is a long process that can impede the development of the rest of their team.
Winning in the NBA with a young point guard is almost impossible unless your point guard has the size of a center. Only one (Markelle Fultz) of the five taken in the lottery of last year’s draft was on a winning team, and he barely played this season...The more likely outcome is what happened with Sacramento and Dallas, both of whom turned their offense over to a 19-year-old point guard (De’Aaron Fox and Dennis Smith Jr., respectively) to predictably disastrous results. The Kings’ net rating was 5.9 points higher without Fox, while the Mavs’ was 10.1 points higher without Smith. It was a trial by fire for both, as they could no longer rely on the overwhelming edge in speed they had at lower levels of the game.
Point guards take a long time to blossom. It’s hard to project them when they are in their mid-20s, much less when they are teenagers.
