It is actually being reported today that the Lakers are already planning to send Bronny to the G league. That means he may have already seen his last minutes in the NBA. He might get a couple minutes on this next road trip, but it is possible his career NBA stats have already been finalized.
If a team decides to send a player to the G League, it doesn't mean the end of his NBA career because a team can recall a player back to the main roster at any time. In Bronny's case, I think that playing in the G League would probably be good for him because his current skills are not enough to compete with other NBA players, and it was clearly noticeable from his performances both during the summer league and the preseason.
